韧性剪切作用与深源流体演化和金矿化的耦合关系

流体形成演化是当前地球科学的前沿领域，但构造－流体－成矿作用的研究有很薄弱。文章通过对流 性质的分析，探讨了地质作用过程中流体演化，韧性剪切带中流体演化与矿化的关系。成矿作用发生于深源流体与上地壳流体的“混合”阶段及流体围岩交代反应阶段。     

延边地区火山岩型金矿地球化学及成矿作用研究

延边地区北部大面积出露中生界（Ｊｓ）火山岩系，为正常的钙碱性系列，同玄武岩－安山岩－石英安山岩组成，以富含Ａｕ，Ａｇ，Ｓｂ，Ａｓ，Ｂｉ为特征，其中的金矿床可分为两类即蚀地型高温热液矿床和浅成中低温线热液成矿，同位素资料表明，其成矿热液主要来自火山岩浆。     

Important Geological Factors Controlling the Formation of Gold Deposits in East China

The major gold deposits in east China are characterized by their occurrence in pre-Cambrian host metamorphic rocks,restriction in some specific stratigraphic-structural terranes,tendentious localization in ductile or ductile-brittle shear zones,association with the syntexis type granitoids,and significant remobilization,superimposition and enrichment by the later stage Mesozoic tectono-magmatic activities.     

Sediment—Hosted Gold Deposits in China_geochemistry and Prospecting

Sediment-hosted gold deposits are the major type of gold resources in china,Concen trated mostly in the two“Triangle Regios“,they are generally hosted in fine-clastic turbidite,hydrothermal chet and marl ranging from cambrian to Triassic in age,structurally controlled by domes,anticlines and second-ordered faults.They are similar to the Carlin-type gold deposits in mineral assemblage and geochemical marks,with an element association closely comparable to those of modern springs and submarine hydrothermal sediments.Organic matter may have played an important role in mineralization .The ore solution may be hydrothermally altered meteoric water developed i areas of local geothermal anomaly.     

江西利山金矿床地质特征及控矿构造

本文较系统地阐述了利山金矿床的各项地质特征，并重点就控矿构造问题进行了总结讨论，认为ＮＷＷ向断裂带严格控制了所有金矿体的产出。ＮＮＥ、ＮＮＷ向断裂与ＮＷＷ向断裂带的交汇部位控制了富矿段的产出。在此基础上初步探讨了矿床成因及找矿方向，这对该地区的找矿评价和开发均具有实际意义     

蚀变带元素地球化学成矿预测法──以金龙山微细浸染型金矿为例

金矿化作用伴围岩蚀变，且多受断裂控制，反映在地球化学上出现某些元素的异常。在已发现一害矿化体并掌握一般控制矿特征的地区，利用已有工程在蚀变带内连续捡块采样，分析有关批示元素，总结有关的地球化学指标，建立地球化学预测模式，对已知矿体及外围异常进行了地球化学评价。
