羊里尾沟金矿是2007~2014年以来在迭部—武都砷汞锑金多金属成矿带上发现评价的一处中型金矿床。矿体主要赋存于下石炭统炭(硅)质板岩,局部赋存于炭(硅)质板岩夹灰岩,两组NW向断裂控制金矿带及矿体的产出,主矿体局部表现为厚度大、品位较富、倾向延伸80m左右、赋矿岩性以炭质板岩为主的大透镜体。金属矿物以黄铁矿为主,次为毒砂、辉锑矿,金矿物为自然金、银金矿,属粒径大部分在0.01~0.037mm之间的微细粒金。下石炭统炭质板岩,NW向断裂破碎带,硅化、黄铁矿化、毒砂化、碳酸盐化围岩蚀变,Au、As、Hg、Sb、W地球化学组合异常等是矿区的主要找矿标志。
The Yanglizougou gold deposit is a medium-sized gold deposit discovered from 2007 to 2014 in the Diebu-Wudu Arsenal Ag-Au polymetallic metallogenic belt. The orebodies mainly occur in the Lower Carboniferous (SIB) slate and locally occur in the carbonaceous (siliceous) slate intercalated limestone. The two NW trending faults control the output of the gold orebodies and ore bodies. The main ore Local body showed thick, grade is rich, tend to extend about 80m, rich in lithology carbonaceous slate-based large lens body. Metallic minerals mainly pyrite, followed by arsenopyrite, stibnite, gold minerals for the natural gold, silver and gold, is a particle size most of 0.01 ~ 0.037mm between the fine grain gold. Lower Carboniferous carbonaceous slate, NW-trending fault zone, silicification, pyrite mineralization, poison sandification, carbonate rock alteration, Au, As, Hg, Sb and W geochemical anomaly etc. The main prospecting symbol.
