江西相山矿田善堂庵地区铀矿地质特征与控矿因素研究

Geological characteristics and analysis of ore-controlling factors of uranium deposits in Shantang'an orefield,Xiangshan area

善堂庵地区位于相山铀矿田北部,通过近几年勘查工作,在北东向巴泉—善堂庵断裂、邹家—布水断裂的夹持部位新发现一条铀矿带,矿带走向北东,沿走向长2200m,宽65～500m,矿化垂幅达691m。矿体受北东向断裂构造、花岗斑岩(斜长花岗斑岩)体控制,岩体内外接触带、岩体与北东向断裂构造的锐角夹持部位是矿体有利赋存地段。矿石类型主要为铀—绿泥石型,局部可见铀—赤铁矿型。

Shantang＇an area is located in the northern part of Xiangshan uranium orefield. Through the exploration in recent years,a uranium belt was found in the clip position of northeast Baquan-Shantang＇an fault and Zoujia-Bushui fault. The strike of this belt is northeast,the length is 2200 meters,the width is 65 ～ 500 meters and the vertical depth of mineralization is 691 meters. Ore bodies were controlled by the northeast fault and granite porphyry（ plagioclase granite porphyry）. The internal and external contact zone and the acute clip position between the intursion rocks and the northeastern fault are favorable ore-forming location. The ore types mainly are uranium-chlorite type,locally are visible uranium-hematite type.
