广西花山航空伽马能谱特征及找矿预测

The aerial gamma energetic spectrum characteristics-related ore prediction in Huashan area,Guangxi

广西花山岩体为多期(次)侵位花岗岩体,在岩体内部具有良好的铀成矿地质条件。文章基于航空伽马能谱实测资料,对花山花岗岩体的放射性分布特征进行了研究。研究结果显示,花山岩体整体处于放射性偏高场高场区域,岩体中心偏南部位的铀含量有明显增高趋势,望高单元的核部和华美单元具有明显的铀迁入特征,F参数高值区分布在望高单元的核部,根据元素的迁移富集规律,圈定出铀矿成矿的有利部位,为扩大华南地区铀矿勘探区域提供了地球物理基础资料。

In Huashan area of Guangxi province occurs the Huashan granitic body with multi-stage intrusion and potential U metallogenic condition.Based on the measured aerial gamma spectrum data this paper analyzes radioactive distribution characteristics of the study area.The result shows that Huashan granitic body occurs in the relative high radioactive field-high radioactive field area and U content tends to be higher at its south central part.At core of Wanggao unit and Huamei unit are characterized by U introduction.High F parameters values are concentrated at core of Wanggao unit.Based on the mentioned above and U migration law possible favorite U mineralization is located providing geophysical basis for expanding U prospecting targets in South China.
