| 1 | 科尔沁沙地东南部地区主要植物叶片性状及其相互关系显示文摘选取科尔沁沙地东南部地区23种主要植物,将其划分成草本、灌木和乔木3种生长型,并分别测定其叶片鲜重(FW)、干重(DW)、叶干物质含量(DMC)、面积(AR)、比叶面积(SLA)和厚度(TH)等6项叶片性状因子。结果表明,草本植物的叶片性状比灌木和乔木变异大;平均SLA和DMC草本<灌木<乔木,DW反之,而TH则没有明显的变化。方差分析发现,除DW和TH外,SLA和DMC在不同生长型中的变化显著,并且SLA与DMC呈显著负相关,说明SLA和DMC是在植物资源利用分类轴上划分植物种类的最佳变量。对于厚度,还需进一步进行研究。 | 刘金环 曾德慧 Don Koo Lee | 2006 | 生态学杂志2006，25，8： | 137 |
| 2 | 青藏高原拉萨地块碰撞-后碰撞岩浆作用的三种类型及其对大陆俯冲和成矿作用的启示:Sr-Nd同位素证据显示文摘青藏高原拉萨地块是揭示印度与亚洲大陆碰撞的最重要的地区之一,其中广泛发育的碰撞—后碰撞岩浆作用记录了这一地区从特提斯洋俯冲消减到印度大陆陆内俯冲的全过程。本文基于对最新的Sr-Nd同位素资料的分析,从高原岩石圈的三种主要地球化学端元入手,分析了拉萨地块碰撞—后碰撞岩浆作用的类型及其在大陆俯冲与成矿作用方面的意义。青藏高原岩石圈可以分为三种主要的地球化学端元,一是青藏高原北部地球化学省(包括羌塘、可可西里和西昆仑)代表的青藏原始岩石圈地幔地球化学端元,42Ma以来在高原北部广泛分布的钾质岩浆岩的Nd-Sr同位素成分比较均一和稳定,同位素比值的范围较窄,^(87)Sr/^(86)Sr=0.707101~0.710536,ε_(Nd)=-2~-9,t_(DM)=0.7~1.3Ga;二是雅鲁藏布江蛇绿岩代表的新特提斯洋地幔端元,^(87)Sr/^(86)Sr=0.703000~0.706205,ε_(Nd)=+7.8~+10,呈印度洋型MORB特征,属于印度洋型地幔域;三是喜马拉雅带地壳基底和花岗岩类显示的喜马拉雅地壳地球化学端元,ε_(Nd)=-12~-25,^(87)Sr/^(86)Sr=0.733110~0.760000,具相对古老的Nd模式年龄,t_(DM)=1.9~2.9Ga。拉萨地块碰撞—后碰撞岩浆作用可以划分出三种地球化学类型,即拉萨地块原地型、亲特提斯洋型和亲喜马拉雅型。这三种岩浆作用类型受控于上述三种地球化学端元在其源区的比例及相互作用。其中,拉萨地块原地型与青藏高原北部地球化学省特征一致,亲特提斯洋型代表了与新特提斯洋俯冲消减及其后的再循环有关的岩浆作用,亲喜马拉雅型岩浆岩的Sr-Nd同位素特征则可能指示了喜马拉雅大陆地壳端元的参与。超钾质火山岩是揭示印度大陆岩石圈向北俯冲的重要证据,印度大陆岩石圈俯冲作用可能同时控制了超钾质岩石和盐类矿床的产出。古老地壳物质作为源区参与了超钾质岩石和盐类矿床的成岩与成矿作用。拉萨地块中部地区的含矿斑岩属于亲特提斯洋型岩浆作用,因此具亲特提斯洋型特征的火山岩、浅成斑岩和深成侵入岩,是进一步寻找铜、钼、金矿床的重要目标。 | 莫宣学 赵志丹 Don J DEPAOLO 周肃 董国臣 | 2006 | 岩石学报2006，22，4： | 79 |
| 3 | 恒山中元古代早期基性岩墙群的单颗粒锆石U-Pb年龄及其克拉通构造演化意义显示文摘华北克拉通中北部变质基底发育大规模的前寒武纪基性岩墙群,由于基性岩墙同位素定年技术存在问题,因此一直未获得岩墙群的确切年龄数据。本文利用单颗粒锆石U-Pb化学法,首次获得恒山地区北西向基性岩墙群的U-Pb年龄为1769.1±2.5Ma,并证明它代表基性岩墙群的侵位年龄,这一年龄数据也是华北克拉通大规模分布的未变质基性岩墙群已知的最古老年龄。综合分析同期岩浆活动的同位素年龄记录,本文提出中元古代早期华北的岩浆侵位发生于伸展构造背景下。 | 李江海 侯贵廷 钱祥麟 H.C.HALLS Don DAVIS | 2001 | 地质论评2001，47，3： | 57 |

| 5 | 男男性行为人群HIV暴露前预防需求与使用障碍研究显示文摘目的:了解MSM对HIV暴露前预防(PrEP)的实际需求及阻碍其使用的相关因素。方法:通过同性社交Blued 6.5.0软件、MSM同伴推荐等方法招募MSM为调查对象,估算样本量600人。利用'问卷星'平台,在调查员的指导下进行匿名电子问卷调查,调查内容包括一般情况、PrEP相关知识和使用意愿与顾虑、PrEP实际需求及PrEP使用自我效能等。结果:共调查622名MSM,知晓和曾使用过PrEP的比例分别为56.4%(351/622)和4.3%(27/622);67.2%(418/622)有PrEP实际需求,PrEP使用自我效能良好的为21.2%(132/622)。结构方程模型分析结果显示,PrEP相关知识和使用顾虑对PrEP使用自我效能发挥直接正向作用,效应系数分别为0.08和0.13,自我歧视是由于PrEP使用顾虑而间接影响PrEP使用自我效能,效应系数为0.035;广义线性混合模型分析结果表明,曾使用过PrEP可增加使用自我效能(OR=5.55);PrEP相关知识和使用顾虑每增加1分,PrEP使用自我效能分别增加0.14倍和0.07倍。担心药物副作用、预防效果和费用者分别占61.1%(380/622)、60.1%(374/622)和53.2%(331/622);期望获取PrEP服务途径主要为CDC(75.6%,470/622)、MSM社会组织(65.4%,407/622)和互联网(63.8%,397/622)。结论:MSM对PrEP呈现高需求与低使用的较大差距,PrEP相关知识缺乏、自我歧视、对药物预防效果、副作用及费用的顾虑是阻碍MSM使用PrEP的因素,故需要建立适合MSM特点的PrEP服务模式,以满足MSM对PrEP干预的需求。 | 石安霞 Don Operario 张志华 赵越 朱晓芳 杨璀 Nickolas Zaller 高攀 王君 孙业桓 张洪波 | 2020 | 中华流行病学杂志2020，41，3： | 28 |
| 6 | Survival outcome of patients with spontaneously ruptured hepatocellular carcinoma treated surgically or by transarterial embolization显示文摘AIM: To evaluate clinical outcomes of patients that underwent surgery, transarterial embolization (TAE), or supportive care for spontaneously ruptured hepatocellular carcinoma (HCC). METHODS: A consecutive 54 patients who diagnosed as spontaneously ruptured HCC at our institution between 2003 and 2012 were retrospectively enrolled. HCC was diagnosed based on the diagnostic guidelines issued by the 2005 American Association for the Study of Liver Diseases. HCC rupture was defined as disruption of the peritumoral liver capsule with enhanced fluid collection in the perihepatic area adjacent to the HCC by dynamic liver computed tomography, and when abdominal paracentesis showed an ascitic red blood cell count of > 50000 mm 3 /mL in bloody fluid. RESULTS: Of the 54 patients, 6 (11.1%) underwent surgery, 25 (46.3%) TAE, and 23 (42.6%) supportive care. The 2-, 4and 6-mo cumulative survival rates at 2, 4 and 6 mo were significantly higher in the surgery (60%, 60% and 60%) or TAE (36%, 20% and 20%) groups than in the supportive care group (8.7%, 0% and 0%), respectively (each, P < 0.01), and tended to be higher in the surgical group than in the TAE group. Multivariate analysis showed that serum bilirubin (HR = 1.09, P < 0.01), creatinine (HR = 1.46, P = 0.04), and vasopressor requirement (HR = 2.37, P = 0.02) were significantly associated with post-treatment mortality, whereas surgery (HR = 0.41, P < 0.01), and TAE (HR = 0.13, P = 0.01) were inversely associated with posttreatment mortality. CONCLUSION: Post-treatment survival after surgery or TAE was found to be better than after supportive care, and surgery tended to provide better survival benefit than TAE. | Young-Joo Jin Jin-Woo Lee Seoung-Wook Park Jung Il Lee Don Haeng Lee Young Soo Kim Soon Gu Cho Yong Sun Jeon Kun Young Lee Seung-Ik Ahn | 2013 | World Journal of Gastroenterology2013，19，28： | 23 |
| 7 | 西藏雅鲁藏布蛇绿岩形成构造环境的地球化学鉴别显示文摘本文对西藏雅鲁藏布蛇绿岩带中部日喀则地区夏鲁蛇绿岩中的基性岩石进行了元素地球化学研究。岩石为低钾亚碱性玄武质岩石,具有低TiO2(0.64%~1.5%)、低K2O(<0.69%)、富Na2O(2.5%~6.0%)、烧失量普遍较高(2.0%~7.5%)的特征,表明样品普遍遭受蚀变。岩石具有与N-MORB类似的稀土元素和总体一致的微量元素特征,但是岩石明显富集大离子亲石元素和亏损高场强元素,显示了洋脊玄武岩向着岛弧岩浆作用的过渡趋势。日喀则蛇绿岩不是典型的洋中脊成因,应为SSZ型蛇绿岩,可能形成于与洋内俯冲有关的SSZ型的弧后或者弧前盆地中。对东西延伸超过1500km的雅鲁藏布蛇绿岩246套基性岩石形成的构造环境进行的地球化学判别,表明至少存在大陆岛弧型、地幔柱-洋内热点型、洋中脊-大洋岛弧型和典型大洋岛弧型等四种类型洋壳,揭示了特提斯洋存在多种构造环境的特征,有利于恢复和还原一个长期演化的、丰富的特提斯洋。 | 李文霞 赵志丹 朱弟成 董国臣 周肃 莫宣学 Don DePAOLO Yildirim DILEK | 2012 | 岩石学报2012，28，5： | 23 |
| 8 | Primary endoscopic approximation suture under cap-assisted endoscopy of an ERCP-induced duodenal perforation显示文摘Duodenal perforation during endoscopic retrograde cholangiopancreatography(ERCP) is a rare complication,but it has a relatively high mortality risk.Early diagnosis and prompt management are key factors for the successful treatment of ERCP-related perforation.The management of perforation can initially be conservative in cases resulting from sphincterotomy or guide wire trauma.However,the current standard treatment for duodenal free wall perforation is surgical repair.Recently,several case reports of endoscopic closure techniques using endoclips,endoloops,or fully covered metal stents have been described.We describe four cases of iatrogenic duodenal bulb or lateral wall perforation caused by the scope tip that occurred during ERCP in tertiary referral centers.All the cases were simply managed by endoclips under transparent capassisted endoscopy.Based on the available evidence and our experience,endoscopic closure was a safe and feasible method even for duodenoscope-induced perforations.Our results suggest that endoscopists may be more willing to use this treatment. | Tae Hoon Lee Byoung Wook Bang Jee In Jeong Hyung Gil Kim Seok Jeong Seon Mee Park Don Haeng Lee Sang-Heum Park Sun-Joo Kim | 2010 | World Journal of Gastroenterology2010，16，18： | 19 |

| 10 | Contributions of biofilm and suspended sludge to nitrogen transformation and nitrous oxide emission in hybrid sequencing batch system显示文摘Hybrid system combines the nature of suspended growth and attached growth has been widely applied to wastewater treatment.In this research, the contributions to N transformation and N2O emission by biofilm and suspended sludge in the hybrid sequencing-batch reactor for a simultaneous nitrification, denitrification and phosphorus removal process were investigated. For the hybrid system,nitrification occurred mostly in the suspended sludge, while the biofilm played the major role in denitrification. The interaction ofthe biofilm and the suspended sludge in the same reactor resulted in a better overall nitrogen removal performance with simultaneousnitrification and denitrification. However, N2O emission was the main end product of nitrogen removal for the hybrid system; whileit was N2 for the biofilm. The relative low N2O emissions from the pure biofilm and the pure suspended sludge corresponded to therelatively high nitrate at the end of the aeration period compared with the hybrid system. | Ingwei Wayne Lo Kwang Victor Lo Don S Mavinic Dean Shiskowski William Ramey | 2010 | Journal of Environmental Sciences2010，22，7： | 17 |
| 11 | 华北基性岩墙群的古地磁极及其哥伦比亚超大陆重建意义显示文摘从华北克拉通的中西部和东部发育的基性岩墙群获得三个精确定年的实际古地磁极位置(VGPs)。华北克拉通中西部恒山GU岩墙的斜锆石U-Pb年龄为1769±3Ma,该岩墙的古地磁给出古地磁极位置在北纬36°,东经247°(dp=2,dm=4);华北克拉通东部DY岩墙的斜锆石U-Pb年龄为1620.8±6.9Ma,获得的古地磁极位置为北纬6.9°东经81.9°(dp=4.31,dm=6.09);东部另一条岩墙LW4的SHRIMP U-Pb年龄为1157±18Ma,获得的古地磁极位置为北纬27.1°东经162°(dp=15.8,dm=18.7)。通过将这三个从基性岩墙获得的华北克拉通古地磁极位置与加拿大地盾的中元古代视极移曲线对比,在中元古代早期(1800~1600Ma),华北克拉通与加拿大地盾一起同属哥伦比亚超大陆,而在中元古代晚期(1600~1200Ma),华北克拉通与加拿大地盾分离,响应哥伦比亚超大陆的最终裂解事件。 | 侯贵廷 Henry HALLS Don DAVIS 黄宝玲 杨默函 王传成 | 2009 | 岩石学报2009，25，3： | 16 |

| 13 | 西藏北部拉萨地块那曲地区约113Ma安山岩岩石成因与意义显示文摘西藏北部拉萨地块广泛分布着早白垩世岩浆岩,由于缺少高质量的年代学和地球化学数据,其岩浆源区和岩石成因迄今未能很好约束。本文报道了北部拉萨地块那曲地区安山岩的锆石U-Pb定年、地球化学和Sr-Nd-Hf同位素数据。那曲安山岩锆石U-Pb年龄为112.7±0.7Ma。岩石为高钾钙碱性系列,富集大离子亲石元素、Th、U和轻稀土元素[(La/Yb)N=6.62~11.68],亏损Nb、Ta、P和Ti等高场强元素。样品具有较高的(87Sr/86Sr)i值(0.7100~0.7126)、负的全岩εNd(t)值(-10.5~-7.8)和负的锆石εHf(t)值(-9.9~-4.7),对应于古老的Nd同位素二阶段模式年龄(1.5~1.8Ga)和锆石Hf同位素地幔模式年龄(1.0~1.6Ga)。综合岩石学、地球化学和区域构造背景研究认为,那曲地区安山岩形成于南向俯冲的班公湖-怒江洋壳岩石圈板片断离的背景,很可能是受早期流体/沉积物熔体交代富集的安多微陆块古老岩石圈地幔物质部分熔融的产物,并经历了不同程度的分离结晶。 | 黄玉 朱弟成 赵志丹 张亮亮 Don DEPAOLO 胡兆初 袁洪林 莫宣学 | 2012 | 岩石学报2012，28，5： | 16 |
| 14 | Does the bile duct angulation affect recurrence of choledocholithiasis?显示文摘AIM:To investigate whether bile duct angulation and T-tube choledochostomy influence the recurrence of choledocholithiasis.METHODS:We conducted a retrospective study including 259 patients who underwent endoscopic sphincterotomy and cholecystectomy for choledocholithiasis between 2000 and 2007.The imaginary line was drawn along the center of the bile duct and each internal angle was measured at the two angulation sites ofthe bile duct respectively.The values of both angles were added together.We then tested our hypothesis by examining whether T-tube choledochostomy was performed and stone recurrence occurred by reviewing each subject's medical records.RESULTS:The overall recurrence rate was 9.3% (24 of 259 patients).The mean value of sums of angles in the recurrence group was 268.3°± 29.6°,while that in the non-recurrence group was 314.8°± 19.9° (P < 0.05).Recurrence rate of the T-tube group was 15.9% (17 of 107),while that of the non T-tube group was 4.6% (7 of 152) (P < 0.05).Mean value of sums of angles after T-tube drainage was 262.5°± 24.6° and that before T-tube drainage was 298.0°± 23.9° in 22 patients (P < 0.05).CONCLUSION:The bile duct angulation and T-tube choledochostomy may be risk factors of recurrence of bile duct stones. | Dong Beom Seo Byoung Wook Bang Seok Jeong Don Haeng Lee Shin Goo Park Yong Sun Jeon Jung Il Lee Jin-Woo Lee | 2011 | World Journal of Gastroenterology2011，17，36： | 15 |
| 15 | 北美西部陆相白垩系-古近系界线孢粉学特征简介--兼评中国东部白垩系-古近系界线研究显示文摘已经报道的北美西部陆相白垩系-古近系界线剖面已达近百处,这些剖面分布在阿拉斯加南部向南经加拿大直到美国南部的新墨西哥州北部的广大北美西部内陆地区,其中很多属迄今所知全球很好的陆相白垩系-古近系界线剖面。这些剖面常有标志性的界线黏土,并伴有其他地球化学、生物地层学特征。因为这些剖面所在地当时都在湿润或半干旱地区内,有利于生物化石,特别是孢粉化石的保存,易于开展孢粉学研究。经过近四十年不懈努力,孢粉学已经成为北美精确确定陆相白垩系-古近系界线最重要的、也是迄今为止所知最为有效的古生物学工具。孢粉植物群在界线上下特征差别显著,容易区分。界线之下含有大量主要繁盛于白垩纪的被子植物花粉,而在临近界线时则突然消失或仅零星出现,界线附近则以一层孢子异常丰富层为古近系底部特征。进入古近纪之后,虽然被子植物花粉有所恢复,但是繁盛于白垩纪的成分却很少出现。北美和新西兰、日本白垩系-古近系界线附近在沉积岩和孢粉学方面的相似性表明这一事件可能是全球性事件。简要回顾和讨论了我国与孢粉学相关的几个热点地区陆相白垩系-古近系界线的研究概况,我国东北及江苏北部和北美西部大部分地区白垩系-古近系界线附近的孢粉植物群及其沉积环境比较类似,在苏北到东北地区范围内首次发现陆相白垩系-古近系界线地层的可能性比其他地区大。 | 刘耕武 Dennis R.Braman 李伟同 Don Brinkman | 2009 | 地层学杂志2009，33，1： | 15 |
| 16 | Continental crust formation at arcs, the arclogite ‘‘delamination''cycle, and one origin for fertile melting anomalies in the mantle显示文摘The total magmatic output in modern arcs,where continental crust is now being formed, is believed to derive from melting of the mantle wedge and is largely basaltic. Globally averaged continental crust, however, has an andesitic bulk composition and is hence too silicic to have been derived directly from the mantle. It is well known that one way this imbalance can be reconciled is if the parental basalt differentiates into a mafic garnet pyroxenitic residue/cumulate(‘‘arclogite'') and a complementary silicic melt, the former foundering or delaminating into the mantle due to its high densities and the latter remaining as the crust.Using the Sierra Nevada batholith in California as a case study, the composition of mature continental arc crust is shown in part to be the product of a cyclic process beginning with the growth of an arclogite layer followed by delamination of this layer and post-delamination basaltic underplating/recharge into what remains of the continental crust.A model is presented, wherein continuous arc magmatism and production of arclogites in continental arcs are periodically punctuated by a delamination event and an associated magmatic pulse every *10–30 My. The recycling flux of arclogites is estimated to be *5 %–20 % that of oceanic crust recycling by subduction. Delaminated arclogites have the necessary trace-element compositions to yield time-integrated isotopic compositions similar to those inferred toexist as reservoirs in the mantle. Because of their low melting temperatures, such pyroxenites may be preferentially melted, possibly forming a component of some hotspot magmas. | Cin-Ty A.Lee Don L.Anderson | 2015 | Science Bulletin2015，60，13： | 15 |
| 17 | Assessment of Pb uptake,translocation and immobilization in kenaf (Hibiscus cannabinus L.) for phytoremediation of sand tailings显示文摘The potential of kenaf (Hibiscus cannabinus L.) for phytoremediation of lead (Pb) on sand tailings was investigated.A pot experiment employing factorial design with two main effects of fertilizer and lead was conducted in a nursery using sand tailings from an ex-tin mine as the growing medium.Results showed that Pb was found in the root,stem,and seed capsule of kenaf but not in the leaf.Application of organic fertilizer promoted greater biomass yield as well as higher accumulation capacity of Pb.In Pb-spiked treatments,roots accumulated more than 85% of total plant Pb which implies that kenaf root can be an important sink for bioavailable Pb.Scanning transmission electron microscope (STEM) X-ray microanalysis confirmed that electron-dense deposits located along cell walls of kenaf roots were Pb precipitates.The ability of kenaf to tolerate Pb and avoid phytotoxicity could be attributed to the immobilization of Pb in the roots and hence the restriction of upward movement (translocation factor < 1).With the application of fertilizer,kenaf was also found to have higher biomass and subsequently higher bioaccumulation capacity,indicating its suitability for phytoremediation of Pb-contaminated site. | HO Wai Mun ANG Lai Hoe LEE Don Koo | 2008 | Journal of Environmental Sciences2008，20，11： | 14 |
| 18 | Long-term follow up of endoscopic resection for type 3 gastric NET显示文摘AIM:To clarify the short and long-term results and to prove the usefulness of endoscopic resection in type 3gastric neuroendocrine tumors(NETs).METHODS:Of the 119 type 3 gastric NETs diagnosed from January 1996 to September 2011,50 patients treated with endoscopic resection were enrolled in this study.For endoscopic resection,endoscopic mucosal resection(EMR)or endoscopic submucosal dissection(ESD)was used.Therapeutic efficacy,complications,and follow-up results were evaluated retrospectively.RESULTS:EMR was performed in 41 cases and ESD in 9 cases.Pathologically complete resection was performed in 40 cases(80.0%)and incomplete resection specimens were observed in 10 cases(7 vs 3 patients in the EMR vs ESD group,P=0.249).Upon analysis of the incomplete resection group,lateral or vertical margin invasion was found in six cases(14.6%)in the EMR group and in one case in the ESD group(11.1%).Lymphovascular invasions were observed in two cases(22.2%)in the ESD group and in one case(2.4%)in the EMR group(P=0.080).During the follow-up period(43.73;13-60 mo),there was no evidence of tumor recurrence in either the pathologically complete resection group or the incomplete resection group.No recurrence was reported during follow-up.In addition,no mortality was reported in either the complete resection group or the incomplete resection group for the duration of the follow-up period.CONCLUSION:Less than 2 cm sized confined submucosal layer type 3 gastric NET with no evidence of lymphovascular invasion,endoscopic treatment could be considered at initial treatment. | Yong Hwan Kwon Seong Woo Jeon Gwang Ha Kim Jin Il Kim Il-Kwun Chung Sam Ryong Jee Heung Up Kim Geom Seog Seo Gwang Ho Baik Kee Don Choi Jeong Seop Moon | 2013 | World Journal of Gastroenterology2013，19，46： | 14 |
| 19 | 西藏当雄南部约54Ma辉长岩-花岗岩杂岩的岩石成因及意义显示文摘近年来在拉萨地块南部识别的多处基性岩浆活动对揭示地幔源区成分和相关动力学问题提供了重要线索。本文对拉萨-当雄一带原认为是早白垩世茶苍卡辉长岩-浦迁花岗岩杂岩中获得了始新世幔源岩浆活动记录。研究区出露的3种岩石类型及其U-Pb锆石年龄分别是正长闪长岩、碱性角闪二长花岗岩(54.0±0.3Ma)和钾玄质碱性辉长岩(53.8±0.4Ma)。其中辉长岩锆石εHf(t)值为-6.6~-4.2、Hf模式年龄tDM为0.88~0.97Ga;二长花岗岩εHf(t)为-10.2~-6.5,Hf地壳模式年龄tDMC为1.5~1.7Ga。三类岩石都具有富碱、富钾特征,它们具相似的稀土和微量元素含量,均显示大离子亲石元素和Pb富集、高场强元素Nb、Ta、Ti和P亏损等特征。闪长岩和花岗岩的Sr和Nd同位素特征相似,87Sr/86Sr比值为0.711~0.712,εNd(t)为-9.1~-7.1;而辉长岩分别是0.708和-4.8~-4.9。本文与拉萨地块南部和中部已有结果共同表明,新生代岩浆岩的分布与成分显示了与俯冲带极性吻合的规律性变化特征,即从雅鲁藏布缝合带向北,岩石的富集组分逐渐增加,越过洛巴堆-米拉山断裂带进入具有地壳基底的中部拉萨地块后,岩石则明显增加了地壳富集组分,很好显示了基底成分对岩浆作用的控制。拉萨地块南部大约47Ma开始出现的富集组分,很可能是中部拉萨地块富集的古老地壳基底物质参与和控制的结果,而与印度大陆地壳物质的俯冲无关。茶苍卡辉长岩可能来源于受到早期俯冲来源流体交代的富集岩石圈地幔物质的部分熔融,而茶苍卡角闪二长花岗岩主要来源于古老地壳物质的重熔,但是有幔源物质参与。茶苍卡辉长岩不同于典型岛弧玄武岩,而与板内玄武岩或伸展背景下形成的玄武质岩石类似,其成因很可能与大约52Ma的特提斯洋壳板片断离和岩浆大爆发有关。 | 赵志丹 朱弟成 董国臣 莫宣学 DEPAOLO Don 贾黎黎 胡兆初 袁洪林 | 2011 | 岩石学报2011，27，12： | 13 |
| 20 | 湖北当阳陆相白垩系-古近系界线层型问题值得深入研究显示文摘陆生恐龙的绝灭是白垩系-古近系界线事件中最引人注目的。陆相地层是恐龙绝灭等事件信息的重要载体。全球白垩纪、古近纪陆相地层发育、分布广泛,单一的白垩系-古近系全球界线层型(GSSP)不能满足建立一个明确而可操作的界线标准的需要,建立陆相白垩系-古近系界线层型很有必要,其意义和重要性实际上不亚于建立GSSP。中国的白垩系、古近系绝大多数为陆相沉积,且陆相白垩系-古近系界线方面存在许多问题,而中国目前正在做陆相地层建阶和完善'中国区域年代地层表'工作,不解决好陆相白垩系-古近系界线问题,中国古近系最下面的一个阶便建不好,'中国区域年代地层表'将不完善,所以建立陆相白垩系-古近系界线层型对于中国更加迫切并具实际价值。全球白垩纪-古近纪过渡时期(特别是古新世早期)的连续陆相生物地层记录十分匮乏,寻找合适的剖面建立陆相白垩系-古近系界线层型非常困难。从轮藻角度出发,湖北当阳跑马岗组露头剖面拥有全球迄今所知最连续丰富多样的白垩纪-古近纪过渡时期特别是古新世早期的陆相生物地层记录。界线层段的介形类生物地层记录也非常连续且丰富多样,并具建立界线层型的其他许多条件。它是中国至今所知惟一具有潜力成为全球(或大区性、或中国)的陆相白垩系-古近系界线层型、也即中生界-新生界界线层型的候选剖面(露头剖面),从而也可能是中国古近系、也即新生界最下面一个阶的最合适的建阶剖面或层型剖面。为此,湖北当阳陆相白垩系-古近系界线层型问题无疑值得重视和深入研究。 | 李伟同 刘耕武 Dennis R.Braman 曹卫生 陈钦保 Don Brinkman | 2010 | 地层学杂志2010，34，2： | 12 |
