辽宁省黑石砬子铁矿地质-地球物理综合研究及深部找矿效果

The comprehensive geological-geophysical study and ore prospecting to depth of Heishilazi iron ore deposit

黑石砬子铁矿床南部的剩余磁异常是人们关注的课题。文章采用综合研究的方法,通过分析铁矿的成矿地质环境、控矿因素、矿床特征,对磁异常进行定量计算,实施地质-地球物理综合推断,推断深部的铁矿体的倾向发生倒转,从而有效地解释了矿区的剩余异常,明确了深部铁矿勘查的具体部位,预测矿区深部隐藏着较大的资源储量。经过深部工程验证,获得了很好的找矿效果。

Residual magnetic anomly in southern part of Heishilazi iron deposit is a subject to which much attention has paid. The paper analyzes metallogenic setting, ore-control factors and characteristics of the iron deposit and calculates quantitatively the magnetic anomly. Geological-geophysical inference is made on the deposit and it is in{erred that dip of iron ore body to depth is overturned. The inference could explain effectively the residual magnetic anomly in the mining district and make clear of location of deep ore bodies for further exploration and predict much more mineral resource to depth of the mining district.
