【摘要】 马厂菁金矿床是一个与碱性侵入体有关的多金属硫化物——石英脉型中温热液金矿床.该矿床位于金沙江——红河深大断裂北段东侧。金矿体赋存于侵入体外接触带蚀变岩断裂内.金矿化主要受构造、岩浆岩、围岩岩性等地质条件控制。本文详细讨论了成矿地质条件及矿床成因问题,这对本类矿床找矿评价和扩大矿区远景具有重要意义.更多还原

【Abstract】 Machangqin gold deposit, which closely related to the alkaline intrusive: bodies, is recognized as belonging to mesothermal polymetallic sulfide—quartz vein type. This gold deposit is located at the east side in the north part of Jinshajiang—Honghe large deep fault, The ore bodies occur in the fracture structures of altered rocks at the outer contact zones of intrusive bodies. The mineralization of gold is controlled by the structural, magmatic, lithologic and other geological conditions. In present paper the geological condition of metallogenesis and the genesis of deposit have been discussed in detail. It is very inportant to mineral prospecting, appraisal of this hind of deposit and to the long—range perspective of enlarging the ore district.更多还原
