摘　　要：华北陆块北缘成矿区是典型的稀有-有色多金属成矿区,成矿作用与广泛发育的燕山期花岗质岩浆活动密切相关。内蒙古中部地处华北陆块北缘成矿区中段,是中国"三稀"资源(稀有、稀土、稀散)大省之一,其中铌(Nb2O5)、稀土储量位居中国之首。以石灰窑和赵井沟两个花岗岩型稀有金属矿床为研究对象,探讨了其成矿背景、成矿特征、成矿要素等方面内容,对找矿标志等进行了总结,推测在内蒙古中部地区可能存在稀有金属的区域性成矿作用。Polymetallic metallogenic belt in the northern margin of the North China craton is a typical non-ferrous and rare metal polymetallic metallogenic area in which mineralization is closely related to well-developed granitic magmatism of Early Yanshan period.The middle of the Inner Mongolia Autonomous Region is located in the middle section of the northern margin of the North China block,and is one of the largest resource provinces with three-type rare mineral resources(rare resources,rare earth,scattered resources)of China.The reserves of Nb2O5 and rare earth are among the first in China.Different characteristics of metallogenic background,metallogenic characteristics and metallogenic elements between Shihuiyao and Zhaojinggou rare metal deposits of Granite type were compared,and the prospecting marks were summarized.It was speculated that regional mineralization of rare metals might exist in the middle of the Inner Mongolia Autonomous Region.
