| 1 | 四川盆地东部地区下志留统龙马溪组页岩储层特征显示文摘四川盆地是中国西南部重要的含油气盆地,在东部和南部地区下志留统龙马溪组页岩广泛发育。在川东南、鄂西渝东地区的勘探井中志留系具有良好的气显示。研究区龙马溪组厚65~516m,底部为一套海侵沉积的富含笔石的黑色页岩,龙马溪组向上和向东砂质和钙质含量增加,演变为浅水陆棚沉积。龙马溪组主要由层状-非层状泥/页岩、白云质粉砂岩、层状钙质泥/页岩、泥质粉砂岩、层状-非层状粉砂质泥/页岩、粉-细粒砂岩、钙质结核、富含有机质非层状页岩8种岩相组成。总有机碳含量(TOC)为0.2%~6.7%。有机质以II型干酪根为主,Ro为2.4%~3.6%。页岩中石英矿物含量在2%~93%,主要呈纹层状或分散状分布,主要为陆源碎屑外源成因。龙马溪组页岩岩心孔隙度为0.58%~0.67%,渗透率为0.01×10-3μm2~0.93×10-3μm2。扫描电镜下龙马溪组页岩微孔隙度为2%左右,主要包括晶间孔和粒内孔,孔隙直径为100nm~50μm。页岩储层的形成机理主要为有利矿物组合、成岩作用和有机质热裂解作用。龙马溪组与美国Barnett页岩具有一定差异,主要表现在龙马溪组页岩埋藏较深、热演化程度较高、含气量较低、储层较致密、以陆源成因石英为主。对于评价下志留统龙马溪组页岩气勘探前景而言,今后须重点加强针对龙马溪组底部黑色硅质岩系石英成因、成熟度、埋藏史、含气量等方面的研究,以及进行详细的古地貌和古环境恢复。 | 刘树根 马文辛 LUBA Jansa 黄文明 曾祥亮 张长俊 | 2011 | 岩石学报2011，27，8： | 228 |
| 2 | 藏南上白垩统大洋红层:岩石类型、沉积环境与颜色成因显示文摘西藏南部上白垩统大洋红层岩石类型有碳酸盐岩、泥质岩和硅质岩.碳酸盐岩又细分为红色有孔虫颗粒灰岩、红色生物碎屑泥晶灰岩、红色含微体生物泥晶灰岩、红色泥晶灰岩、红色-杂色内碎屑砾状灰岩等类型;泥质岩主要为红色页岩;硅质岩有红色放射虫岩、红色(含)放射虫硅质岩、红色硅质岩.红色页岩沉积环境为碳酸钙补偿面(CCD)之下、受浊流影响的下斜坡/盆地相;而红色灰岩为远洋沉积环境下由先成的较浅水上斜坡红色灰岩层通过滑移、滑塌沉积在下斜坡页岩内.野外观察、显微镜、扫描电子显微镜、X射线衍射和漫反射数据表明,细小的、分散状出现的赤铁矿是导致藏南上白垩统大洋红层呈现红色的根本原因,赤铁矿不是碎屑来源的,而是同沉积期-成岩早期阶段的产物.无论是红色页岩还是红色灰岩,都以出现高含量Fe2O3和低含量FeO为特征,铁主要以三价形式出现,指示了一种氧化条件.藏南大洋红层沉积时期,在东特提斯洋上斜坡-下斜坡-盆地环境下广泛出现高含量溶解氧的氧化条件,导致该条件出现的主要因素是气候变冷、洋流活动和海洋-大气氧通量改变. | 胡修棉 王成善 李祥辉 Luba Jansa | 2006 | 中国科学(D辑)2006，36，9： | 36 |
| 3 | Multi-Stage Basin Development and Hydrocarbon Accumulations: A Review of the Sichuan Basin at Eastern Margin of the Tibetan Plateau显示文摘Sichuan Basin is one of the uppermost petroliferous basins in China. It experienced three evolutionary phases which were marine carbonate platform(Ediacaran to Late Triassic), Indosinian-Yanshanian orogeny foreland basin(Late Triassic to Late Cretaceous) and uplift and tectonic modification(Late Cretaceous to Quaternary). The present-day tectonics of the Sichuan Basin and its periphery are characterized by three basic elements which are topography, basement type and surface structure, and two settings(plate margin and interior). Therefore, be subdivided into five units which have different structure and tectonic history. The basin contains five different sets of source rocks with thickness up to 2 500 m. These source rocks were well preserved due to the presence of Middel–Lower Triassic evaporites(>~200 m) and thick terrestrial sediments filling in the Indosinian-Yanshanian foreland basin(>3 000 m). The uplift and erosion since Late Cretaceous has significant influence on cross-strata migration and accumulation of oil and gas. The multi-phase evolution of the basin and its superimposed tectonic elements, good petroleum geologic conditions and diverse petroleum systems reveal its bright exploration prospects. | Shugen Liu Bin Deng Luba Jansa Zhiwu Li Wei Sun Guozhi Wang Zhili Luo Ziquan Yong | 2018 | Journal of Earth Science2018，29，2： | 17 |

| 5 | Geological Evolution of the Longmenshan Intracontinental Composite Orogen and the Eastern Margin of the Tibetan Plateau显示文摘The Longmenshan Range is a tectonically composite intracontinental orogen.Its structure,deformation and spatial evolution reflect multiple kinematic eposides and variable dynamics especially during Post-Middle to Post-Late Triassic time.Field work,lower-temperature thermochronological data and U-Pb detrital zircon ages indicate document down-dip zonation and along-strike segmentation demonstrated by significant differences in geological structure,intensity of deformation and deformationinvolved strata,uplift and cooling processes.Low-temperature thermochronology and U-Pb detrital zircon ages reveal a period of tectono-thermal quiescence with slow uplift and cooling during post Early Norian to Rhaetian orogeny,followed by rapid cooling and uplift during the Late Cenozoic accompanied by coeval southeastward thrusting and southwestward propagation of defromation.The Longmenshan Range formed by S-N striking compression exerted by the Qinling orogen,E-W striking compression by the Tibetan Plateau and SE-striking compression by the Yangtze Plate.We propose a southwestward propagation model for the Longmenshan Range based our observations of zonation,segmentation and composite evolutional processes during the Late Triassic superimposed by development of the differential uplift and cooling processes that shows southern segments of the Longmenshan Range during Post-Jurassic times. | 刘树根 邓宾 李智武 Luba Jansa 刘顺 王国芝 孙玮 | 2013 | Journal of Earth Science2013，24，6： | 12 |
| 6 | Hydrothermal Dolomite in the Upper Sinian (Upper Proterozoic) Dengying Formation, East Sichuan Basin, China显示文摘Hydrothermal Dolomite(HTD) is present in the Upper Sinian(Upper Proterozoic) Dengying Formation, east Sichuan Basin, China. The strata are comprised by primary dolomite. The HTD has various textures, including zebra dolomite, subhorizontal sheet-like cavities filled by saddle dolomite and breccias cemented by saddle dolomites as well occur as a fill of veins and fractures. Also co-occur MVT type lead-zinc ores in the study area. The δ13C and δ18O isotopes of HTD in the Upper Sinian Dengying Formation are lighter than those of the host rocks, while 87Sr/86 Sr is higher. The apparent difference in carbon, oxygen and strontium isotopes, especially the large difference in 87Sr/86 Sr isotopes ratio indicate crystallization from hot basinal and/or hydrothermal fluids. Saddle dolomite was precipitated at temperatures of 270-320°C. The diagenetic parasequences of mineral assemblage deposited in the Dengying Formation are:(1) dolomite host rock →sphalerite-galena-barite-fluorite;(2) dolomite host rock →saddle dolomite →quartz;(3) dolomite host rock → saddle dolomite→bitumen;(4) dolomite host rock → saddle dolomite → barite. The mean chemical composition of the host dolomite matrix and HTD didn't change much during hydrothermal process. The fluids forming the HTDs in the Dengying Formation were mixtures of freshwater from the unconformity at the top of Sinian, fluids from diagenetic compaction and hydrocarbon generation & expulsion from the Lower Cambrian Niutitang Formation mudstones or the Doushantuo Formation silty mudstones, and hydrothermal fluids from the basement. The hydrocarbon reservoirs associated with the HTD were mostly controlled by the basement faults and fractures and karsting processes at the unconformity separating Sinian and Cambrian strata. The hydrocarbon storage spaces of HTD included dissolved cavities and intercrystalline pores. Dissolution cavities are extensive at the top of Dengying Formation, up to about 46 m below the unconformity between Sinian and Cambrian and were generated mainly during karstification. Hydrothermal alteration enhanced the reservoir property of the Dengying Formation dolomites with 3%-5% increase in porosity. No agreement has been reached why zebra dolomite occurs only in the Upper Sinian strata, which would indicate that HTD mineralization occurred during two different periods, each of them related to major extensional tectonic event. The early one related to the Xingkai taphrogenesis(Z2-?1)and the later one to the Emei taphrogenesis(D2-T2). But, all the data from saddle dolomite suggest that the predominant crystallization occurred during the latter event. | LIU Shugen HUANG Wenming JANSA Luba F.

| 7 | Upper Cretaceous oceanic red beds in southern Tibet:Lithofacies,environments and colour origin显示文摘Application of mineralogy, geochemistry, sedimentary petrology, and sedimentology methods result in better understanding of the genesis and paleoenvironmens of the Upper Cretaceous oceanic red beds exposed in southern Tibet. The red beds comprise the Chungde Formation. Nine lithofacies recognized within this formation are: red foraminiferal packstone/grainstone, red microfos- sils wackestone, red marlstone with microfossils, red marlstone, red to variegated floatstone and rud- stone (debris flow), red shale, red radiolarite, red chert with radiolaria, and red chert. Sedimentary structures and textures, microfossils, and carbonate content show that the Chuangde Fm was depos- ited near the base of a continental slope in a deep oceanic basin environment, with the basin floor below the carbonate compensation depth (CCD). Red marlstones and limestones intercalated within red shales represent slides and slumps from the upper part of the continental margin. Debris flow and turbidity deposits consist of volcaniclastic, fossilliferous rudstone and floatstone, and very thin cal- careous mudstone, intercalated with red shales. The Upper Cretaceous oceanic red beds in southern Tibet are characterized by high Fe2O3, low FeO, which indicates an oxic diagenetic environment, resulting in precipitation of hematite. The latter occurs as finely, disseminated ferric oxide giving the red color to the rocks. It is concluded that the red beds in southern Tibet were deposited under highly oxygenated bottom conditions in the deep ocean basin. Such conditions not only occurred in a deep ocean basin as indicated by the occurrence of pelagic red shale deposited below the CCD, but also extended up the continental margin as indicated by the presence of red colored marlstones and limestones embedded in the Chuangde Fm. The latter were deposited above CCD, most probably on the continental slope. The oxic bottom conditions are interpreted to be a result of a combination of climate cooling, active bottom ocean circulation, and change in the ocean-atmosphere oxygen budget. | Jansa Luba | 2006 | Science China Earth Sciences2006，49，8： | 11 |
| 8 | Reservoir Characteristics and Preservation Conditions of Longmaxi Shale in the Upper Yangtze Block, South China显示文摘The Upper Ordovician-Lower Silurian Longmaxi Shale in the Upper Yangtze block represents one of the most important shale gas plays in China. The shale composition,porosity,organic thermal maturity,and methane sorption were investigated at the Qilongcun section in the Dingshan area,southeastern Sichuan Basin. The results show that the Upper Ordovician-Lower Silurian Longmaxi Shale contains:(1) sapropelic I organic matter;(2) a 40-m thick bedded sequence where total organic carbon(TOC) content is > 2%;(3) a 30-m thick layer at the base of the Longmaxi Shale with a brittle mineral content higher than 50%; and(4) a mean methane adsorption capacity of 1.80 cm^3/g(7 MPa pressure). A positive correlation between TOC and sorbed gas indicates that organic matter content exerts an important control on methane storage capacity. Based on the analysis of the shale reservoir characteristics,the lower member of the Longmaxi Shale can thus be considered a favorable stratum for shale gas exploration and exploitation. It has similar reservoir characteristics with the Longmaxi Shale in the Jiaoshiba area tested with a high-yield industrial gas flow. However,based on tectonic analysis,differences in the level of industrial gas flow between the low-yield study area and the high-yield Jiaoshiba area may result from different tectonic preservation conditions. Evidence from these studies indicates the shale gas potential of the Longmaxi Shale is constrained by the reservoir and preservation conditions. | RAN Bo LIU Shugen Luba JANSA SUN Wei YANG Di WANG Shiyu YE Yuehao Christopher XIAO ZHANHG Jian ZHAI Cangbo LUO Chao ZHANG Changjun | 2016 | Acta Geologica Sinica(English Edition)2016，90，6： | 6 |
| 9 | Biostratigraphy of a Paleocene-Eocene Foreland Basin boundary in southern Tibet显示文摘This study of the Paleocene—Eocene boundary within a foreland basin of southern Tibet, which was dominated by a carbonate ramp depositional environment,documents more complex environmental conditions than can be derived from studies of the deep oceanic environment.Extinction rates for larger foraminiferal species in the Zongpu-1 Section apply to up to 46%of the larger foraminiferal taxa. The extinction rate in southern Tibet is similar to rates elsewhere in the world,but it shows that the Paleocene fauna disappeared stepwise through the Late Paleocene,with Eocene taxa appearing abruptly above the boundary.A foraminifera turnover was identified between Members 3 and 4 of the Zongpu Formation—from the Miscellanea—Daviesina assemblage to an Orbitolites—Alveolina assemblage.The Paleocene and Eocene boundary is between the SBZ 4 and SBZ 5,where it is marked by the extinction of Miscellanea miscella and the first appearance of Alveolina ellipsodalis and a large number of Orbitolites. Chemostratigraphically,theδ^(13)C values from both the Zongpu-1 and Zongpu-2 Sections show three negative excursions in the transitional strata,one in Late Paleocene,one at the boundary,and one in the early Eocene.The second negative excursion ofδ^(13),which is located at the P—E boundary,coincides with larger foraminifera overturn.These faunal changes and the observedδ^(13)C negative excursions provide new evidence on environmental changes across the Paleocene—Eocene boundary in Tibet. | Xiaoqiao Wan Xi Wang Luba F.

| 11 | Composition and Origin of Ferromanganese Crusts from Equatorial Western Pacific Seamounts显示文摘In the equatorial western Pacific, iron-manganese oxyhydroxide crusts(Fe-Mn crusts) and nodules form on basaltic seamounts and on the top of drowned carbonate platform guyots that have been swept free of pelagic sediments. To date, the Fe-Mn crusts have been considered to be almost exclusively of abiotic origin. However, it has recently been suggested that these crusts may be a result of biomineralization. Although the Fe-Mn crust textures in the equatorial western Pacific are similar to those constructed by bacteria and algae, and biomarkers also document the existence of bacteria and algae dispersed within the Fe-Mn crusts, the precipitation, accumulation and distribution of elements, such as Fe, Mn, Ni and Co in Fe-Mn crusts are not controlled by microbial activity. Bacteria and algae are only physically incorporated into the crusts when dead plankton settle on the ocean floor and are trapped on the crust surface. Geochemical evidence suggests a hydrogenous origin of Fe-Mn crusts in the equatorial western Pacific, thus verifying a process for Fe-Mn crusts that involves the precipitation of colloidal phases from seawater followed by extensive scavenging of dissolved trace metals into the mineral phase during crust formation. | WANG Guozhi JANSA Luba CHU Fengyou ZOU Can SUN Guosheng | 2015 | Journal of Ocean University of China2015，14，2： | 2 |
| 12 | 太平洋西北平顶海山上环礁型碳酸盐建造与白垩纪赤道洋流(英文)显示文摘深海钻探揭示构成环礁的浅水碳酸盐建隆覆盖沉积在太平洋西北部平顶海山之上.相对于现今珊瑚-藻类生物构成的环礁而言,白垩纪和古新世孤立的环礁的四周边缘生物含量甚少,造礁能力下降.这些环礁浅水碳酸盐沉积在火山基座的顶部,在Albian初期、Albian末期、Maastrichtian晚期和始新世中期发生沉没.早期研究认为这些碳酸盐体系经历了地面暴露阶段以及随后的海侵淹没阶段.然而,一个事实是,环礁沉没仅发生在当太平洋板块背负着平顶海山向北漂移过程中,并且是经过南纬7°以后.几个不同的假说用来解释该时期环礁沉没现象,包括环礁暴露、喀斯特化、地面侵蚀、增强赤道上升洋流、缺氧和/或者富营养的浑浊水的出现等.文中在太平洋平顶海山深海钻孔的沉积、生物地层和古纬度数据综合研究基础上,提出一种新模式用于解释晚白垩世-古新世浅水碳酸盐建造的沉没.与以前的模式不同的是,文中提出,这些晚白垩世-古新世'环礁'之所以发生沉没,原因是受到原始环南赤道洋流(pSEC)的影响,导致一种对分泌碳酸盐的生物不利环境的产生.而且,当这些平顶海山漂移到南纬5°时,即赤道古纬度带,许多浅水碳酸盐建造之上,铁锰结核开始沉积.同时,平顶海山下沉到溶解氧极小层(海平面之下400~1 100 m)和原始环南赤道中层洋流(pEIC)区域,碳酸盐生产停滞.当平顶海山漂移经过赤道后(北纬0~3°),并且下沉到南赤道中层洋流(pEIC)深部海平面之下~1 100 m,远洋沉积才开始.因此,沉积学数据提供确切证据表明,太平洋中部赤道地区在过去100 Ma大部分时期内,和现在非常类似地受到赤道地转洋流系的影响. | Luba JANSA | 2005 | 地学前缘2005，12，2： | 2 |
| 13 | 用于制备聚氨酯纳米复合物的高岭石粒子的表征(英文)显示文摘Clay such as kaolinite, is commonly used as an additive to modify the thermal properties of polymer. In this paper, the morphology, composition, shape and structure of kaolinite was characterized by various advanced techniques. The TEM/ EDX data showed that the kaolinite had a larger particle size and a Si/Al ratio of 1.8. The individual particle of kaolinite was a single crystalline. TEM also showed that these particles were always stacked together due to the presence of electrostatic cohesive energy and hydrogen bond between plaletes. The PAS FTIR spectra showed that no absorbance of hydroxyl group for hydration water in hydrogen bond region or at 1650cm- 1 was observed at room temperature. It meant a little ability to adsorb water for kaolinite particle. Kaolinite clay also showed no change for its PAS FTIR spectra with increasing temperature. The TGA results revealed that kaolinite almost doesn′ t lose weight at 60℃ due to loss of dehydration of absorbed water, however, it will decomposed around 510℃ and lose its hydroxyl functional group in the form of water (dehydroxylation). The result is consistent with that of PAS FTIR analysis. This suggests that the structural hydroxyl group on the surface of individual kaolinite clay particle is very stable below 500℃ , and the kaolinite composed polymer could be got by the reaction of its stable structural hydroxyl group with isocynate group of polyurethane prepolymer. | 李再峰 王义银 Luba S.Kotlyar Keng H.Chung | 2003 | 无机化学学报2003，19，11： | 2 |
