甘肃唐坝金矿地质特征与矿床成因浅析
Geological characteristics and genetic analysis of Tangba gold deposit in Gansu Province
摘要
Abstract
In this paper,the gold deposit genesis of Tangba gold deposit in Gansu Province is described in detail on the basis of the introduction of the geological setting of Tangba gold deposit.It is believed that the ore-forming fluid of Tangba gold deposit is mainly acidic tectonic hydrothermal fluid formed by regional faults,and the ore-forming fluid is enriched in the lower part of the middle-thick limestone due to longitudinal bending and folding.The gold ore body is located at the collapse site and the interlayer slip tectonic plane formed by the complex back(toward)inclined turning point,and the ore body shape is saddle-like,lamellar,lens-like,and netted.The ore type is mainly quartz vein type,and the mineralization is mainly limonite,pyrite and silicitization.The alteration of surrounding rock is mainly chlorite and sericite.关键词
