| 摘 要： | 本文主要讨论了田湾金矿田韧性剪切带的成矿构造地球化学特征。田湾矿田各个矿点在空间上均受剪切带的控制 ,表明剪切带是重要的控矿因素。田湾矿田剪切带制约着成矿流体的来源、运移和演化 ,剪切应力、应变作用对成矿元素的活化迁移具有重要的影响 ,为金的成矿提供了物质基础和创造了条件

| Abstract: | This paper focused on the tectonogeochemical characteristics of the ductile shear zone in the Tianwan gold orefield. Every mineralized site is controlled by the ductile shear belt, so it became the key factor for the gold mineralization in the Tianwan orefield. The ductile shear zone played an important role in localization of gold ore deposits: (1) The ductile shear zone confines the source, migration and evolution of ore-formingfluid; (2) Shear stress and deformation accelerate the remobilization of mineralized elements; (3) The ductile shear zone supplies space for ore-forming fluid deposition. |
