The mineral inclusions in zircon from gneisses in ultra-high pressure (UHP) zone of the Dabie Mountains were identified by using a laser Raman microspectrometer. Coesite occurs as inclusions in zircons from all types of gneiss. Other important minerals, such as jadeite, omphacite, aragonite, barite, and anhydrite were also found as inclusion minerals. These discoveries indicate that ( i) gneissic country rocks had metamorphosed at the same time as the enclosed eclogites; and (ii) SO4-2 -bearing fluids were presentin the UHP metamorphic process, which is manifested by occurrence of barite and anhydrite coexisting with coesite.

2017年8月中国科学院海洋研究所在西太平洋低纬度海区的卡罗琳洋脊CM4海山开展了多学科综合调查,发现该海山山体表面分布着大量的铁锰结壳。本文对该海山的5个铁锰结壳样品进行了矿物学和地球化学研究,利用X射线衍射(XRD)、电感耦合等离子光谱及质谱(ICP-OES、ICP-MS)等测试技术分析了铁锰结壳的矿物组成、主微量元素和稀土元素含量,并进一步探讨了铁锰结壳的成因类型。结果表明,该海山铁锰结壳的矿物组成以水羟锰矿为主,含有少量钡镁锰矿、水钠锰矿、针铁矿、纤铁矿、石英和方解石。该海山铁锰结壳的Mn、Fe、Co、Ni、Cu元素平均含量分别为24.24%、15.14%、0.16%、0.34%、0.01%。与全球各大洋海山区铁锰结壳相比,该海山样品的Cu含量很低。该海山铁锰结壳的稀土元素(REY)含量相对偏低,总体为轻稀土(LREE)富集;稀土(REY)配分模式显示相对平坦的特征,呈明显的Ce正异常,轻微的Y负异常和Ho正异常。样品的矿物组成、元素比值、元素组合等都表明该海山铁锰结壳属于水成成因,未受明显的成岩作用影响。

青海可可西里自石炭纪以来经历了复杂的构造演化和地表过程,形成了集高山、宽谷、夷平面、冰川、热泉、河流和湖泊等地貌元素为一体的高原高寒地貌,同时还包括了蛇绿混杂岩带、活动断裂带、地震遗迹和火山遗迹等地质元素。在调研前人研究资料和实地野外考察基础之上,根据IUCN(2005)提出的13类地质主题分类标准将区内的地质遗迹分为地质构造、火山和地热遗迹、山脉、地层剖面、河流和湖泊、现代冰川、冰期遗迹7类,共计60余处地质遗迹点。可可西里地质遗迹对重建古特提斯构造域、研究天然地震机制、青藏高原北部隆升过程及全球气候变化均具有重要的意义。基于可可西里区内地质遗迹和前人资料恢复出可可西里石炭纪以来经历了8个构造演化阶段。
