浅谈甘肃省高台县慕少梁金矿区成矿地质特征及成因探析

Discussion on the Geological Characteristics and Genesis of Mineralization in the Musaoliang Gold Mine Area, Gaotai County, Gansu Province

慕少梁金矿位于甘肃省高台县,矿床受断裂控制,受多期构造影响,属于中低温岩浆热液矿床,出露的地层为中元古界变质岩,酸性岩浆侵入活动强烈,该构造带为区域上的主要含金石英脉分布点,有良好的找矿远景。本文从该矿区的地层、构造、地球化学特征、围岩蚀变、成矿规律等方面阐明该矿区的成矿地质特征和成因,为该区的找矿工作提供一定的理论依据。

The Mushaoliang gold deposit is located in Gaotai County,Gansu Province.The deposit is controlled by faults and influenced by multiple tectonic periods.It belongs to a medium low temperature magmatic hydrothermal deposit.The exposed strata are Middle Proterozoic metamorphic rocks with strong acidic magma intrusion activity.This tectonic zone is the main distribution point of gold bearing quartz veins in the region and has good prospecting prospects.This article elucidates the geological characteristics and genesis of mineralization in the mining area from the aspects of stratigraphy,structure,geochemical features,surrounding rock alteration,and mineralization laws,providing a theoretical basis for the exploration work in the area.
