摘要
本文详细探讨了连山关地区早元古代富铀矿床的主导赋矿因素,揭示了沿太古代—下元古代不整合面两侧分布的钠交代体对该区脉型铀矿的赋矿意义,明确其主要找矿方向是寻找受浪子山组下部层位中的脊状钠交代体基部控制的富铀矿床,指出了成矿有利地段。
In this paper main ore-hosting factor of the Early Proterozoic richuranium deposit in the Lianshanguan area is discussed in detail.Thesignificance of sodium metasomatic bodies which are distributed along bothsides of the Archaean-Lower Proterozoic unconformity in the emplacementof the vein-type uranium deposit in the area is revealed. It is explicit thatthe main prospecting direction is looking for rich uranium deposit whichis controlled by the basal part of ridged sodium metasomatic bodies in theLower Langzishan Formation. The promising area for uranium prospectingis pointed out.
