摘要
本文通过对东矿带主要是红羊裴柳地段的地层产状、地球物理特征分析,并与磁铁石英岩为标志层进行对比,建立首钢迁安铁矿区红羊裴柳地段的控矿构造模式。该地段整体为以柳河峪—红石崖向斜为主体的复向斜,该向斜的核心在十八亩台,柳河峪主矿体在深部向北西转折,并逐渐变薄,与柳西矿体构成倒转向斜。前裴庄紧密倒转向斜、红石崖倒转向斜为其次级褶皱构造。区内断裂构造对其形态完整性和产状有一定影响。红羊裴柳控矿构造模式的建立为该区的深部找矿工作提供了依据。
Ore-controlling structural pattern of Hong-Yang-Pei-Liu area was proposed after analyzing formation occurrence and geophysical characteristics as well as making stratigraphic correlation on the base of maker bed,magnet quartzite.On the whole,the study area shows a structure of synclinorium.Liuheyu-Hongshiya syncline,whose core locates at Shibamutai area,serves as the main part of that synclinorium.Liuheyu main orebody turns to the north west in the deep and gradually becomes thinner.It together with Liuxi orebody constitute a inverted syncline.Qianpeizhuang inverted syncline and Hongshiya inverted syncline serve as secondary folds of that inverted syncline.Faults in the researched area have certain influence on shape integrity and occurrence of ore beds.The establishment of this structural pattern provides a kind of basis for the deep prospecting work in Hong-Yang-Pei-Liu section.
