摘要: 河台金矿由蚀变糜棱岩型和石英脉型二类金矿组成。地质地球化学研究结果表明：石英脉型金矿形成早于韧性剪切变形，与海西-印支期深熔岩浆活动有关；蚀变糜棱岩型金矿则与燕山晚期岩浆活动有关，主体成矿晚于糜棱岩期，并继承和叠加了早期石英脉型金矿。金矿床成矿温度为中温，成矿深度为2-3km，矿质具围岩和基底双重来源。

Abstract: There are 2 types of gold deposits-the quartz -vein deposit and alteratic mylonite deposit in Hetai Gold Province. Gelolgy and geochemistry research show:the quartz-vein gold deposits which were formed earlier than the forming of ductile shear zone in the area are relevant to Variscan-Tndosinian acid magmatism,But the alteratic mylonite gold deposits which were mainly formed latter than the dectile shear zone are relevant to the Yanshanian acid magmatism. All the deposits in the province belong to mesothermal deposits. The minerogenic depth is from 2 to 3 kilemeter. The source of the gold is mainly from country rock but some gold is probably from foundation bed.
