摘要
本文根据煌斑岩与金矿的成因关系，以及黔东湘地区汞、铅、锌等多金属矿产的分布特点，并结合１∶２０万区域地球化学测量成果，提出了黔东北地区汞、铅、锌成矿带为同一热源下，由于热传导产生的温度差异而形成分异的并可能包含有Ａｕ、Ａｇ等贵金属的一成矿体系，并对该体系的成因建立了成因模式。同时，运用该模式对区内待发现的Ａｕ、Ａｇ等金属矿产作出了找矿远景区的预测。
On the basis of the genetic relationship of the gold deplsits to lamprophyres, the distribution of the Hg-Ph-Zn polymetallic deposits in East Guizhou-West Hunan, and the data of the regional geochemical survey at the 1∶200, 000 scale, a genetic model for the polymetallic ore belts, in which the Hg, Ph, Zn one belts are regarded as being resulted from the differentiation of metal elements in hydrothermal orebearing fluids due to difference in temperature of heat conduction under the same heat source, is established. and the prospect of Au, Ag deposits have been determined with aids of the models.
