塔吉克斯坦某金矿矿床地质特征及成因分析

Geological Characteristics and Genetic Analysis of a Gold Deposit in Tajikistan

塔吉克斯坦某金矿位于中亚成矿带与特提斯喜马拉雅成矿带的交汇部位,属于岩浆热液型金矿,矿体数量较多,形态不一,主要呈层状和脉状,规模较大的主要为Ⅵ-1和Ⅳ-2。矿体空间位置主要受矿区中酸性侵入岩、波依马扎尔背斜、石炭系马尔古佐尔岩系中不同岩性之间形成的硅/钙岩性界面以及氧化还原界面共同控制。

A gold deposit in Tajikistan is located at the intersection of the Central Asian metallogenic belt and the Tethys Himalayan metallogenic belt.It is a magmatic hydrothermal gold deposit.There are many ore bodies with different shapes,mainly layered and veined,and the larger ones are mainly VI-1 and IV-2.The spatial location of the ore body is mainly controlled by the intermediate-acid intrusive rocks in the mining area,the Boymazar anticline,and the silicon/calcium lithologic interface and redox interface formed between different lithologies in the Carboniferous Marguzor rock series.
