摘要
龙门场银金多金属矿为次火山热液型矿床。地表以铁帽型银金矿为主、深部为银多金属原生矿,矿体受断裂构造控制,具有"上Au-Ag、下Ag-Cu多金属"的垂向分带特征。东南部喷发不整合面与逆冲推覆断裂构造复合带是寻找隐伏银多金属矿的有利地段,矿区深部及外围有较好的找矿前景。
The Longmenchang silver-gold polymetallic deposit in Youxi County is a deposit of the subvolcano and hydrothermal fluid type. On the earth surface there mainly exists the electrum of the gossan type and in the deep part there is the primary ores of silver polymetals. The orebody is controlled by faulted structures and is possessed of the gold- silver and silver-copper polymetals vertical zoning characteristics. The composition plane of
