摘要
小背坞矿区位于浮梁县境内,该矿区地处皖赣边界低山丘陵区,与之相邻的矿山为大背坞金矿。为更好的总结小背坞矿区的成矿规律,给地质找矿提供可靠的依据,从地层特征、构造特征、岩浆岩特征三个方面,分析了小背坞金矿的地质特征,在基础上,对矿区的地球物理和化学特征以及矿化特征进行研究,最后得出矿床的成矿规律与找矿方向。结果表明,小背坞金矿床以自然金为主,多产于毒砂包体裂隙和黄铁矿裂隙中。
The Xiaobeiwu mining area is located in Fuliang County.The mining area is situated in the low mountain and hilly area of the Anhui Jiangxi border,and the adjacent mine is the Dabeiwu gold mine.In order to better summarize the mineralization laws of Xiaobeiwu mining area and provide reliable basis for geological prospecting,the geological characteristics of Xiaobeiwu gold deposit were analyzed from three aspects:stratigraphic characteristics,structural characteristics,and magmatic rock characteristics.Based on this,the geophysical and chemical characteristics as well as mineralization characteristics of the mining area were studied,and finally the mineralization laws and prospecting directions of the deposit were obtained.The results indicate that the Xiaobeiwu gold deposit is mainly composed of natural gold,which is mainly produced in the fissures of arsenopyrite inclusions and pyrite.
