摘要
通过对测区遥感解译环形构造与1∶5万土壤地球化学测量元素异常产生的叠加关系进行分析比较,认为具有叠置、套合关系的环形构造和元素异常具有相同的内在地质成因关系。选择测区内扎赉河农场Cu多金属元素异常区开展野外地质调查验证,在两者交集部位发现了(黄铁矿、孔雀石、黄铜矿)矿化构造蚀变岩(带).这一实践过程为区域地质找矿工作早期确定元素异常矿化位置起到了标示作用.
Carboniferous strata are well developed in Fengshou area of Aohan Qi, Inner Mongolia. The Upper Carboniferous Jiujuzi Formation, composed of a set of terrigenous clastic rocks, is specific in the region. Based on the rock fabrics and vertical variation regular pattern, assemblage, one sequence of third-order is recognized, including two sequences of forthorder and five sequences of fifth-order （high frequency cyclic sequence）.
