寒山金矿床赋存的剪切带有两期变形活动。早期韧脆性变形作用是以位错滑移、双晶作用和重结晶作用等变形机制为主，形成各种类型的片糜岩。在变形过程中，大量流体进行水／ 岩反应。晚期变形作用以碎裂和破裂机制为主，形成各种脆性裂隙和角砾岩带。在早期开放的变形环境下，有利于成矿热液的活动和富集，是寒山金矿的主成矿期；晚期的脆性变形使金矿进一步富集 The occurrence of shear zone in the Hanshan gold deposit has two stages of deformation activities. The early ductile-brittle deformation is dominated by deformation mechanisms such as dislocation slip, twinning and recrystallization, and various types of phyllite are formed. During deformation, a large number of fluids undergo water / rock reactions. Late deformation is dominated by fragmentation and rupture, forming various brittle fractures and breccia belts. In the early open deformation environment, is conducive to the activity and enrichment of hydrothermal fluids, is the main mineralization of the Hanshan gold deposit; late brittle deformation of the gold further enrichment
