摘要
通过对区域重力资料反演河北省莫霍面,进而探讨莫霍面与矿集区的关系,指出:河北省幔坡带是大型金及铅锌等多金属的成矿聚集区,常有大型特大型矿床产出;幔阶区是多金属及沉积矿产聚集区,矿床规模一般不大;幔隆区盛产石油、煤等沉积矿产,多为大型矿床(田);幔坳区矿产主要为铅、锌等多金属。
Shallow crust metallogenic mechanism is closely related to different types of deep-seated structures.The Moho can well indicate the deep tectonic characteristics.This paper deals with the relationship between the Moho and the ore concentration areas through reconstruction of the Moho based on regional gravity data obtained in Hebei Province.Large-size gold,lead-zinc and other ore deposits are existent in the mantle slope zone;polymetallic and sedimentary ore deposits occur in the mantle-terrace area,with the sizes being smaller than those in the mantle slope zone;large-size coal,oil and some other sedimentary ore deposits are abundant in the mantle uplift zone;lead,zinc and other polymetallic ore deposits are abundant in the mantle depression zone.
