摘要
The Dongji gold (sliver) deposit in Zhenghe County is situated at the interjunction between the Zhenghe northeast-trend fault zone and the east fringe of Dongkeng volcanic basin. The deposit was discovered in the rhyolite-porphyry (subvolcanic rocks) which is scattered over the unconformaity surface between Late Proterozoic metamorphics and Mesozoic strata. The orebody is controlled by the internal structure in rhyolite-porphyry. The main useful constituent of the deposit is Au, accompanying Ag. Based on the geological characteristics, metallogenic regularitity, the deposit should belong to subvolcanic thermal type deposit.
