【摘要】 我国存在8个金矿成矿带，每个金矿带均由数个金矿床密集区构成我国已发现的大型金矿床均赋存于金矿床密集区中，具有与中小型金矿床密切共生的特点；因此，金矿床密集区的存在是寻找大型金矿床的区域性标志之一．此外，古老地质体的含金性、区域岩浆活动与火山作用、区域构造和区域地质演化史等特征也构成了大型金矿床的区域性找矿标志．根据上述找矿标志的综合分析结果，我国大型金矿床找矿工作的重点应放在西北地区．更多还原

【Abstract】 China has 8 gold mineral belts, each of which is composed of several concentrated areas of gold deposits. All the large-sized gold deposits in China occur in the concentrated areas of gold deposits, and are closely aariated with the medium- and small-sized gold deposits. Therefore, the existence of the concentrated areas of the gold deposits may serve as a regional indicator for the prospecting of large-sized gold deopits In addition, the gold bearing feature of palcogoological theies, the regdrial magmatism and volcanism, the regional tectonism, and the regional geological evolutionary history may serve as regional indicators for the prospecting of large-sized gold deposits. It can thus be concluded, in line with the comprehensive analytical results of the prospecting criteria mentioned above, that the large-sized gold deposits to be prospected in China should be focused on the northwestern China.更多还原
