| 摘 要： | 北香是丹池成矿带上的一个重要构造隆起区,成矿条件良好,但是近四十年的地质勘查未能实现找矿的重大突破。通过对矿区成矿特征及控矿条件的分析,认为矿床明显受NW向同生沉积断层的控制,具有喷流沉积和后期热液叠加改造的两期成矿特征。目前发现的矿体仅是矿床上部脉状矿,其下部的下泥盆统中应存在层状似、层状的厚大矿体。

| Abstract: | Beixiang is an important structure rise on Danchi ore belt with a favorable ore forming condition but there is no obvious breakthrough in geological exploration in recent 40 years.It is believed that the deposit is obviously controlled by NW trending synsedimentary fault and characterized by two stage mineralization of spout sedimentation superimposed and transformed by late stage hydrothermal fluid through the analysis on metallogenic character and ore controlling condition of the mine.The orebodies which have been found so far are ore veins in upper part of the deposit only,there should be thick stratiform like or stratiform orebodies occurring in Lower Devonian series. |
