| 2 | 新疆北部二叠纪基性岩墙群岩浆作用及其动力学背景显示文摘新疆北部西准噶尔、吐哈盆地、东天山、西天山以及塔里木东北缘广泛发育的二叠纪(260-290Ma)基性岩墙群与塔里木大火成岩省形成时代相近。基性岩墙群主量元素与MgO含量具有较好的相关性,富集Rb、Ba和Sr等大离子亲石元素以及轻稀土元素,亏损Nb、Ta和Ti等高场强元素,无明显Eu异常,与岛弧岩浆特征相似。εNd(t)值为-11.25-7.86,初始N(87Sr)/N(86Sr)值为0.703-0.710。西天山基性岩墙群亏损轻稀土元素,塔里木东北缘亏损Sr。新疆北部二叠纪基性岩墙群岩浆可能起源于富集型软流圈地幔源区,岩浆演化过程中存在不同程度的地壳物质或俯冲交代岩石圈地幔的混染,其中西准噶尔、东天山、西天山和吐哈盆地岩墙经历了板片俯冲流体交代的岩石圈地幔混染,东天山及塔里木东北缘基性岩墙在岩浆演化过程中受到明显的地壳物质混染。新疆北部二叠纪基性岩墙群可能是地幔柱岩浆作用不同演化过程的产物。 | 林瑶 汤庆艳 张铭杰 焦建刚 陈思童 虎啸 | 2014 | 地球科学与环境学报2014，36，3： | 14 |
| 3 | 新疆南天山东段早石炭世——早二叠世花岗岩类及其对南天山洋盆闭合时间的约束显示文摘选择南天山东段早石炭世-早二叠世典型花岗岩类,即阿訇开里得南岩体、盲起苏岩体、东泉戈壁岩体和库米什北岩体进行岩石学与地球化学对比研究.结果表明,这些岩体属于准铝质-过铝质高钾钙碱性系列花岗岩,富集Ba、Rb、Th、U等大离子亲石元素,亏损Nb、Ta、Zr、Hf等高场强元素,稀土元素配分模式呈右倾型,富集轻稀土元素、亏损重稀土元素,铕出现中等负异常(δEu=0.52~0.96).基于上述相似特征,并结合前人研究成果,认为它们形成于陆-陆碰撞环境.基于南天山造山带东西段高压变质岩、岩浆岩、沉积岩和蛇绿混杂岩等方面的岩石成岩年龄对比,认为南天山晚古生代构造演化过程具有区域差异性,碰撞作用在其东段发生于早石炭世,而在其西段发生于晚石炭世.南天山洋东段闭合时间早于西段. | 尼加提.阿布都逊 木合塔尔.扎日 贾晓亮 | 2016 | 现代地质2016，30，2： | 3 |
| 4 | Geochronology of the Dong Tso Ophiolite and the Tectonic Environment显示文摘The wedge shaped Dong Tso ophiolitic block is distributed near the transition point from the western to the middle sub–belt of the Bangong–Nujiang suture zone.The ophiolite is characterized by well–developed cumulate rocks that are mainly composed of cumulate and massive gabbros.In the cumulate gabbros,the adcumulate amphiboles are distributed extensively around the plagioclase and residual pyroxene grains;hence,the rocks are named adcumulate amphibole–gabbro.In this study,the formation age of the ophiolite has been estimated to be 166±4 million years(Ma)by the sensitive high–resolution ion microprobe(SHRIMP)II U–Pb isotopic analysis of the zircons from the adcumulate amphibole–gabbro;the40Ar/39Ar plateau age was estimated to be 148.19±1.53 Ma,which should represent the emplacement time of the ophiolite,by isotopic dating of the pure amphibole mineral from the amphibole–schist.Two different suits of volcanic lavas have been recognized in this work.The purple colored pillow basalts have high TiO2and P2O5contents,and are rich in light rare earth elements(LREEs),large–ion lithospheric elements(LILEs)and high–field–strength elements(HFSEs),the characteristics that are the typical of the oceanic island basalt(OIB).On the other hand,other massive basaltic andesites of celadon color are poor in MgO;rich in Fe2O3,LREEs,LILEs,and HFSEs;and especially characterized by negative Nb and Ta anomalies,the properties that establish the andesites as continental arc volcanic rocks.It is concluded that hotspots had developed in the old Dong Tso basin,the oceanic basin that had been developing from middle Jurassic(166 Ma)or even before and emplaced northward in late Jurassic(about 148 Ma). | LI Jianfeng XIA Bin XIA Lianze XU Lifeng LIU Weiliang CAI Zhourong YANG Zhiqing | 2013 | Acta Geologica Sinica(English Edition)2013，87，6： | 2 |
