衡阳市清水塘矿区金、银成矿地质背景分析

An Analysis on Metallogenic Geological Background of Au and Ag of Qingshuitang Mining Area in Henyang,Hunan

清水塘矿区主要含矿地层是下古生界浅变质岩，代表地槽构造层，受地洼阶段的岩浆侵入。由于构造岩浆多期活动的叠加和改造，形成金银成矿的有利条件。地洼阶段的岩浆活动不仅提供了成矿的驱动力，而且提供了成矿物质来源。

The principal ore bearing strata in Qingshuitang mining area are lower Paleozoic metamorphic rocks,which stand for geosynclinal structural layer and were intruded by diwa magmatic rocks.The favourable condition for gold silver metallogenesis resulted from multi epoch tectonism and magmatism,which were of benifit to the metallogenesis not only in its dynamics but also in material source.
