相山铀矿田北部石马山(612)矿床深边部找矿探讨

Discussion on prospecting the depth and margin of Shimashan deposit(No.612) in northern Xiangshan uranium ore field

近几年相山铀矿田北部多个铀矿床深边部找矿取得了较大的突破,找矿空间进一步扩大,特别是铀成矿与次火山岩(脉)体有着密切联系的规律愈加明了。通过与石马山(612)矿床位置毗邻的中型以上岗上英(613)铀矿床类比,阐述了矿床地质背景、成矿地质条件和控矿地质因素,并分析石马山(612)等矿床探采资料,认为石马山(612)矿床深边部存在着类似岗上英(613)矿床控矿的构造和次火山岩(脉)体,并可发现盲矿体,为该铀矿床深边部找矿提出了依据和方向。

In recent years, prospecting the depth and margin of several uranium deposits in northern Xiangshan uranium ore field has taken breakthrough and has extended the exploration space, it was clean that the uranium mineralization are closely related with subvoleanie rocks（veins）. By comparing with nearby medium-sized Gangshangying uranium deposit （No.613）, in geological background, geological conditions, controlling geological factors, and analyzing the exploration and mining data, the depth and margin of Shimashan deposit （No.612） was believed to bear the similar structure and subvoleanic rocks （veins） of Gangshangying deposit （No.613）, which may infer to blind ore body. This provides the evidence and direction of prospecting the depth and margin of this uranium deposit.
