我国是世界上大陆地震频发、受地震灾害影响最为严重的国家之一。尤其是青藏高原地区,陆内地震空间分布广、震源深度浅、成因类型复杂、灾害损失严重,是典型的地震多发地带,开展地震地质调查工作的需求日益迫切。本文结合区域地质资料,以高精度卫星遥感影像和DEM高程数据为基础,对日喀则地区活断层进行精细解译。结果表明,日喀则地区活断层主要集中在境内裂谷及其周缘,其构造活动性具有空间差异,东部裂谷内活断层构造活动性强于西部各裂谷,各个裂谷内活断层构造活动性也呈现明显的分段性特征。同时,本文综合考虑日喀则地区活断层特征、地形地貌特征及地层岩性3个因素,对该地区所辖2.4个乡镇的地震灾害潜在风险评估初步结果表明,该地区地震灾害“极高风险”“高风险”“高-中风险”的乡镇有57个,约占全区乡镇总数的2.%。

贵州三穗县龙湾铀矿床是近年勘查发现的大型铀矿床,矿体呈层状、似层状产于震旦-寒武系老堡组黑色岩系中。前人对该矿床开展了矿床地质和地球化学研究,但铀的赋存状态、成矿物质来源和成矿环境尚不明确。本文选取龙湾矿床南部的老棚剖面为研究对象,开展矿物学和全岩元素地球化学研究。研究结果表明铀主要以沥青铀矿和钛铀矿等的独立铀矿物形式存在于磷灰石矿物边缘、裂隙及孔洞处,部分以类质同象形式赋存于磷灰石的晶格中。全岩地球化学分析结果显示样品Y/Ho值为16.3~63.2.均值为40.3),Zr/Hf值为33.6~79.3(均值为42.3),靠近上地壳的值;样品具有相对平坦的稀土元素配分模式,显示无-弱Eu正异常(δEu为0.2.~1.19,均值为0.82.;硅质岩Ge/Si值为1.2.×10^(-6)~0.15×10^(-6)(均值为0.47×10^(-6)),均接近现代海水平均值,表明龙湾铀矿床成岩成矿物质来源主要为陆源风化碎屑物质,受到海底热水作用的影响小。样品V/(V+Ni)值为0.43~0.98(均值为0.80),Ni/Co值为1.80~58.0(均值为12.7),具有明显Ce负异常(δCe值为0.31~0.81,均值为0.60),表明龙湾铀矿床形成于还原沉积环境中。综合研究表明,在新元古代晚期-晚古生代早期,黔东地区大陆风化作用为海洋提供了铀,在还原条件下形成龙湾黑色岩系型铀矿床。

昆山矿床位于大湖塘钨多金属矿田的南部,产出石英细脉带型W-Mo-Cu矿体。该矿床的成矿过程可以划分为黑钨矿-石英阶段(Ⅰ)、辉钼矿-石英阶段(Ⅱ)、黄铜矿-石英阶段(Ⅲ)及石英-方解石阶段(Ⅳ)。本文通过流体包裹体岩相学、显微测温、激光拉曼光谱和稳定同位素研究,探讨了昆山矿床的成因机制。研究结果表明,昆山矿床发育纯气相型(PG)、纯液相型(PL)、富液两相水溶液型(WL)三类包裹体。Ⅰ阶段主要发育WL型流体包裹体,并有少量PG型包裹体,均一温度为2.6～388℃,盐度为0. 5%～13. 8%NaCleqv,密度为0. 54～0. 90g/cm^3;Ⅱ阶段亦主要发育WL型和少量PG型包裹体,其均一温度为2.1～390℃,盐度为0. 5%～12. 7%Na Cleqv,密度为0. 51～0. 93g/cm^3;Ⅲ阶段主要发育WL型包裹体,均一温度为2.8～376℃,盐度为0. 7%～11. 2.NaCleqv,密度为0. 57～0. 91g/cm^3;Ⅳ阶段主要发育WL型包裹体,并有少量的PL型包裹体,其均一温度为173～2.8℃,盐度为0. 4%～11. 8%NaCleqv,密度为0. 76～0. 97g/cm^3。主成矿阶段流体属于中高温、中低盐度、中等密度流体,成矿晚阶段流体属于中低温、中低盐度、中高密度流体。包裹体气相成分主要是H_2.,亦有少量CH_4和CO_2.成矿流体总体上属于H_2.-NaCl-(CH_4-CO_2.体系。Ⅰ、Ⅱ和Ⅲ阶段成矿流体的δD值为-92.～-56‰,计算获得的δ^(18)O水值为3. 8‰～6. 4‰;石英-方解石阶段的δD值为-68‰～-58‰,δ^(18)O水值为0. 5‰～0. 7‰。H-O同位素结果表明,昆山矿床主成矿阶段的流体以岩浆水为主,成矿晚阶段有少量的大气降水加入。金属硫化物的δ^(34)S值分布集中,其值为-1. 5‰～3. 0‰,表明成矿流体中的硫主要来自深源岩浆。辉钼矿-石英阶段的石英包裹体中CO_2.δ^(13)CV-PDB值为-6. 6‰和-5. 9‰,平均-6. 3‰;晚阶段石英-方解石脉中方解石的δ^(13)CV-PDB值为-12. 3‰～-10. 2.,平均-11. 0‰,表明昆山矿床主成矿阶段流体中的碳主要由花岗岩浆提供,且受低温蚀变作用的影响,而晚阶段方解石脉中的碳还受到了双桥山群沉积有机物质的影响。成矿流体的冷却作用是导致昆山矿床钨、钼和铜沉淀的主要机制。

川滇黔铅锌多金属成矿区位于特提斯成矿域与环太平洋成矿域交界地带的扬子陆块西南缘,并广泛分布了全球罕见的碳酸盐岩容矿的后成热液型富锗铅锌多金属矿床,其铅锌品位特高、储量大、富含稀散元素锗和贵金属银,经济价值巨大,备受广泛关注。针对制约该区深部找矿突破的成矿构造动力学背景及其响应机制、矿源—输运—聚集成矿过程、铅锌锗元素超常富集—巨量聚集成矿机制、矿床类型归属与铅锌多金属成矿系统等重大理论问题,历经2.余年,通过区域地球物理剖面探测、矿田构造解析、典型矿床精细解剖及矿床地球化学、实验地球化学等系统研究,在成矿理论方面取得重要研究进展:(1)提出了富锗铅锌矿形成于印支期碰撞造山过程的陆内走滑构造系统,解析并厘定了断褶构造组合样式及成矿构造体系,建立了构造分级成矿-控矿、矿体空间定位模式;(2.系统概括了矿化空间组合结构及矿床成矿规律,查明了"矿源—输运—聚集"成矿过程,揭示了铅锌共生分异机制及铅锌锗超常富集成矿机制;(3)提出了具有一定普适性的会泽型铅锌矿床新类型,建立了矿床成矿系统及流体"贯入"—交代成矿模型。在此基础上,提出了陆内走滑构造系统控矿—流体"贯入"-交代成矿论(构造控矿—流体"贯入"成矿论)。应用该理论研发出适用于该类矿床深部勘查技术方法系列,取得了近些年来川滇黔地区一系列找矿突破和新进展。该研究进展不仅为川滇黔成矿区矿床勘查技术研发及深部找矿突破提供了理论支撑,而且将在扬子陆块西南缘乃至特提斯成矿域的类似矿床研究和找矿勘查部署中发挥重要的指导作用。
