豫南灵山岩体铀矿化特征

地处豫南的灵山岩体,分布着丰富的矿产资源。笔者以灵山岩体铀矿化分布特征为切入点,阐述灵山岩体铀矿化特征。该岩体铀矿化受构造、裂隙的控制,有利成矿部位在岩体中构造带与脉岩相交复合部位,矿化富集地段多含铁质、锰质和泥质,且热液蚀变发育。铀源来自岩体。具有4种矿化类型。总结其矿化特征,对豫南新县岩体、商城岩体的找矿具有一定指导意义。

Uranium mineralization characteristics of the Lingshan intrusion in southern Henan

The Lingshan intrusion in southern Henan contains abundant mineral resources. The paper discusses the distribution characteristics of uranium mineralization of the intrusion and then elucidates characteristics of uranium mineralization of the intrusion. The uranium mineralization is controlled by structure and fractures and sites favorable to mineralization lie at sites of intersection and compounding of the structural zones and dikes in the intrusion. The zone of mineralization concentration mostly contains iron, manganese and mud and hydrothermal alteration is well developed. The uranium source comes from the intrusion. There are four types of mineralization. The analysis of the mineralization characteristics may guide ore search in the Xinxian and Shangcheng intrusions in southern Henan.
