布列亚—老爷岭—兴凯铀成矿区成矿地质特征

Geological characteristics of Bulieya-Laoyeling-Xingkai uranium metallogenic region

布列亚一老爷岭一兴凯铀成矿区位于我国东北黑龙江省的中俄边境,是一跨国界的铀成矿区,其中发现一批火山岩型、交代岩型、含煤砂岩型和砂岩型等铀矿床。成矿区铀源丰富,多期次侵入的花岗岩体出露广;火山机构多,中新生代盆地发育,是铀成矿有利区域。俄罗斯境内投入了大批探矿工程量,铀矿勘查程度较高,获得了较好的找矿效果。

Bulieya-Laoyeling-Xingkai uranium metallogenic region is situated at Sino-Russian border in Heilongjiang of Northeast China. A number of volcanic type, metasomatite type, coal-bearing sandstone and sandstone-type uranium deposits have been found in this uranium region. The region is favorable uranium metallogenic area where have been rich source, intrusive granite rock plutons massissue exposed wide, many volcanic edifice and developed Cenozoic basin. A lot of exploration engineering for uranium prospecting have been performed in Russia part of this uranium region and numerous important information have been obtained from those exploration works. And good prospecting results have been obtained.
