摘要
西南天山的锑矿床可划分为碳酸盐岩型、碎屑岩型和浅变质岩型 3类 ,并以后 2类为主 ,锑矿床主要特点是锑汞、锑金、锑银共生。查汗萨拉锑银矿床容矿岩系为碎屑岩 ,成矿物质来源于矿源层 ,断裂活动是成矿的主导因素之一。萨瓦亚尔顿金锑矿床赋存于浅变质岩系 ,矿体受一组早期为韧性、中晚期为脆性的剪切带控制 ,成矿物质多来源 ,成矿具多期多阶段特点 ,剪切作用活动及演化是重要的控矿因素。
Antimony deposits in Southwest Tianshan are divided into three types, that is, carbonate rock type, clastic rock type and low-grade metamorphic rock type. The clastic rock type and low-grade metamorphic rock type are main types. The antimony deposits are characterized by Sb-Hg, Sb-Au, Sb-Ag paragenetic associations. The host rocks of the Chahansala antimony-silver deposit are clastic rocks, the ore-forming materials mainly came from source beds, and the rupture activity is one of the leading factors of mineralization. The deposit occurs in low-grade metamorphic rock, the ore bodies are controlled by shear zones that are ductle in early period but brittle in middle-late period. The ore-forming materials are varied sources, the metallogenic characteristics are multiphases and multistages, and shearing activity and evolution are important controlling factors.
