陕西旬阳砂硐沟汞锑矿含矿构造特征及成因分析

Analysis of structural characteristics and origin of ore containing Shaanxi Xunyang sand shidonggou mercury antimony

旬阳县砂硐沟汞锑矿区位于南秦岭山阳-旬阳汞锑成矿带,公馆郧西汞锑多金属矿田的南部。该矿区汞锑含矿体受褶皱构造(背斜)和断裂构造的联合控制,通过对控(含)矿构造,富矿空间的构造结构面组合特征研究并对初步建立的"背斜+一刀"的成矿模式的建立,同时对成矿构造的来源通过对成矿流体,稀土分析等综合研究后认为,成矿物质可能来源于地壳深部,已有的勘查工程及找矿成果表明,该矿床属低温热液矿床。

The Sorghum Ditch Mercury Sulfide Mine in Xunyang County is located in the south of the QinhuangXunyang mercury-antimony metallogenic belt and the western part of the Yunxi mercury-antimony polymetallic ore field.In this study,the mercury-antimony ore-bearing body is controlled by the fold structure（anticline） and the fault structure,and the structural characteristics of the structure of the ore-bearing and ore-rich structures are studied and the ＂anticline ＋ And the source of ore-forming tectonics through the ore-forming fluid,rare earth analysis and other comprehensive research that the ore-forming material may be derived from the deep crust,the existing exploration and prospecting results show that the deposit Is a low temperature hydrothermal deposit.
