赤城古弧形构造带,是一个向南凸出的弧形构造,形成于五台-吕梁运动期;分布于第一构造层红旗营子群内,受各期构造运动影响,褶皱复杂、断裂发育,岩浆活动频繁。与纬向构造体系、祁吕系和新华夏构造体系成复杂的复合关系。具有一般山字型构造的形成条件,多次泥巴模似试验重演它的成生过程和最终形态,经实地考察,相吻合。古弧形构造控制了新生构造的展布和岩浆活动、沉积作用、成矿作用。发现较多的物化探异常矿点,有良好的找矿远景。
The ancient arc-shaped structural belt in Chicheng is a curved structure protruding southward and formed in the Wutai-Luliang movement. It is distributed in the Hongqiying sub-group of the first structural layer and affected by various tectonic movements with complex folds and faults Development, magmatic activity is frequent. And the latitudinal tectonic system, the Qilu line and the Xinhuaxia tectonic system into complex complex relationship. With the formation of the general shape of the mountain shape conditions, repeated simulations of mud simulations repeated its birth process and the final shape, the field investigation, consistent. The ancient arcuate structure controls the distribution and magmatism of the new structure, sedimentation and mineralization. Discovery of more geophysical and geochemical anomalies, have good prospects for prospecting.
