邹家山4号带岩性控矿因素在探矿过程中的应用

Applications of Lithological Ore-controlling Factors in Mineral Prospecting of No.4 Ore Zone in Zoujiashan Uranium Deposit

邹家山4号带铀矿体产状既有北东向、也有东西、南北和北西等走向,矿体产状复杂多变,控矿因素主要为构造和岩性控矿。为了摸清4号带岩性控矿的规律,合理布置探矿工程、提高探矿效率,着重对邹家山4号带岩性接触带附近矿体进行探采对比分析与说明,研究表明,4号带岩性接触界面形态变化较大,致使附近矿体产状发生变化,当岩性接触界面平缓时,易形成北东、北西和东西向铀矿体;当岩性接触界面陡变时,易形成北西和北东向铀矿体;当岩性接触界呈平缓的弯曲状时,易形成东西、北东和南北向铀矿体。

The occurrence of No. 4 ore zone in Zoujiashan uranium deposit is complex,which includes NE,EW,SN and NW trend,ore-controlling factors mainly include lithology and structure. For figuring out regularities of lithological ore-controlling factors of the No. 4 ore zone,laying out prospecting works reasonably,improving efficiency of prospecting,ore bodies around contacting belt of No. 4 ore zone are exploited,described and analyzed. Research shows the rocks contact interface of No. 4 ore zone has great morphological changes,resulting in changes in the vicinity of ore occurrence,when the the rocks contacted interface is gradual,the uranium ore-bodies of NE,NW and EW trend are easy to form;when the the rocks contact interface is steep,the uranium ore-bodies of NW and NE trend are easy to form;when the the rocks contact interface presents a gentle curve,the uranium ore-bodies of EW,NE and SN trend are easily formed.
