太行山北段“三稀”元素成矿有利区浅析

Analysis of "three rare elements" metallogenic favorable area in northern Taihang Mountain

太行山北段位于大兴安岭-太行山-武陵山深断裂带,乌龙沟~上黄旗深断裂带、灵山~紫荆关深断裂带纵贯全区,深部构造为太行山幔坎,属太行山-武陵山重力梯度带的组成部分。活动阶段为基底形成期,稳定~活化阶段为盖层发育期,活化阶段为本区最重要的内生矿产成矿期,"三稀"元素也具有一定的成矿潜力。

The northern section of Taihang Mountain is located in the Daxinganling Taihang Wuling deep fault zone.The Wulonggou shanghuangqi deep fault zone and the Lingshan Zijingguan deep fault zone run through the whole area.The deep structure is the Taihang Mountain mantle ridge,which is a part of the Taihang Wuling mountain gravity gradient zone.The active stage is the basement formation stage,the stable activation stage is the caprock development stage,and the activation stage is the most important metallogenic stage of endogenetic minerals in this area.The "three rare" elements also have certain metallogenic potential.
