通过综合研究,在黑龙江流域及其邻区厘定出36种构造-物质组合类型,6个基本大地构造单元。据岩石成分和地质建造所反映的放射性地球化学定量和定性参数,划分出5个放射性地球化学省和8个放射性地球化学分异区。工作区内包括3条水文地质褶皱带和2个水文地质自流盆地区,共划分出9个成矿省,30个成矿区,206个矿结;2个铀成矿省、2个潜在的铀成矿省、3个含铀省,其中包括27个铀矿区或潜在铀矿区、含铀区。系统总结了氟-钼-铀建造、以及水成和复合成因铀矿建造中维季姆型、拉科夫型、奇科伊型、伊玛型、铀-煤型、铀-地沥青和铀-硫化物型、楚-萨雷苏型、乌奇库杜克型、达尔马托夫和马林诺夫型、巴尔科夫型等主要矿床类型产出的地质环境和找矿预测标志,并对阿尔丹铀矿省、克鲁伦一奥廖克马铀矿省、布列亚-佳木斯-兴凯潜在铀矿省、锡霍特-阿林铀矿省进行了成矿潜力评估,在此基础上圈出了建议进一步工作的23片铀成矿远景区;另外,还重点在我国境内划分出8片铀成矿远景区,它们均为寻找外生后成砂岩型铀矿的有利地区。
Through comprehensive study, 36 types of tectonic-matter assemblages and 6 basic tectonic units were determined in Heilongjiang River Basin and its adjacent areas. According to the radioactive geochemical quantitative and qualitative parameters reflected by the rock composition and geological construction, five radioactive geochemical provinces and eight radioactive geochemical differentiation zones are divided. The work area consists of three hydrofacies fold zones and two hydrogeological basin valleys. There are 9 metallogenic provinces, 30 metallogenic zones and 206 gold mines; 2 uranium metallogenic provinces and 2 potential uranium Mineralization Province, three uranium-bearing provinces, including 27 uranium mines or potential uranium deposits, including uranium. This paper summarizes the construction of fluorine-molybdenum-uranium and the formation of Widymu, Rakovsky, Chico, Imam, Uranium-Coal, Uranium-Asphalt and Uranium - Geological environment and ore-prospecting prediction for the main deposit types such as sulphide type, Chu-Salissa type, Uchikuduc type, Dalmatov and Malinov type, Balck type and etc. The potential mineralization potential was evaluated for the Ardan Uranium Province, the Krulung-O Loyoma Uranium Province, the Bria-Jiamusi-Xingkai Uranium Deposit, and the Sikhute-Arlin Uranium Province, where On the basis, 23 uranium metallogenic prospect areas suggested for further work are encircled. In addition, 8 uranium metallogenic prospect areas are also emphatically delineated in our country, all of which are favorable areas for finding exogenous post-forming sandstone-type uranium deposits.
