布鲁嘎里河砂金矿产于兴华渡口群下兴华组和晋宁期花岗岩分布区。研究区为低山丘陵 ,经长期风化剥蚀和堆积形成了一系列侵蚀堆积地貌。第四纪松散物覆盖在下兴华组地层和花岗岩之上。目前已圈定 2条矿体。矿体连续性好 ,平面上呈条带状 ,多为粒状、板状、片状。 NE、NW向断裂不但控制区内的地貌形态 ,也为砂金的形成提供了有利地质条件。砂金分布区应该是原生金矿 (化 )的集中区 ,在普查勘探砂金的同时更要注意寻找原生金矿 ,在兴华渡口群中出露的韧性剪切带是寻找原生金矿的有利部位。
The Bhagari River gold deposit is located in the Xiaxinghua Formation and the Jinning Period granite distribution area of the Hinghua Du Kou Group. The study area is a hilly area. After long-term weathering, denudation and accumulation, a series of erosion-accumulation landforms were formed. Quaternary loose material covered the Lower Xinghua Formation and granite above. Has been delineated 2 ore body. Ore body continuity is good, flat strip, mostly granular, plate, flake. NE and NW fractures not only provide geomorphological features within the control area, but also provide favorable geologic conditions for the formation of placer gold. The distribution of gold deposits should be the concentrated area of primary gold deposits. At the same time, it is necessary to pay more attention to find primary gold deposits while surveying the gold deposits. The ductile shear bands exposed in the Hinghua Ferry Group are the favorable sites for finding primary gold deposits .
