东坪金矿成矿研究

近年来，一些地质工作者认为，东坪金矿是产于碱性杂岩体中的重熔岩浆期后热液矿床，属于贫硫化物破碎带钾质蚀变岩型金矿。本文从宏观和微观两方面对该矿床的赋矿岩石和赋矿构造提出新的认识，认为变形、变质和剪切是矿化的直接动力，褶皱与剪切带是该金矿的联合控矿构造。

METALLOGENETIC STUDY OF DONG PING GOLD MINE

In recent years many geologists have claimed that Dong Ping Gold Mine occurred in remelted hydrothermal deposits after the magma stage in the alkaline rocks and that the Mine is of the type of poor sulphide,broken belts,potassic altered rocks.In both macrocosmic and microcosmic aspects,the study brings about a new view on the gold-bearing rocks and structures of the Mine.It is believed that deformation,metamorphism amd shearing are the direct motive force in mineralization and that folds and shear zones are the joint orebody-controlling structures in the Mine.
