黑龙江鸡岭林场多金属矿地质特征及找矿标志

Geological characteristics and prospecting criteria of Jiling Linchang polymetallic deposit in Heilongjiang Province

本区位于兴安岭—内蒙地槽褶皱区,伊春—延寿地槽褶皱系茂林—木兰褶皱带中段;西邻小兴安岭—松嫩地块断(坳)陷带东部。区域上经历了早古生代、中生代构造-岩浆活动,花岗岩侵入体大面积分布。大地构造位置属地壳活动带,构造复杂,岩浆活动频繁,周围分布着众多的金、银、铁、铅、锌、钼等金属矿床(点),为区域成矿有利地段。

This area is located in the Xinganling Inner Mongolia geosynclinal fold area,the middle part of Maolin Mulan fold belt of Yichun Yanshou geosyncline fold system,and the east of Xiaoxing'anling Songnen block fault(depression)zone in the West.It has experienced early Paleozoic and Mesozoic tectonic magmatic activities,and granite intrusions are widely distributed.The geotectonic location belongs to the crustal active zone with complex structure and frequent magmatic activities.There are many gold,silver,iron,lead,zinc,molybdenum and other metal deposits(spots)around it,which is a favorable area for regional mineralization.
