中文摘要:
      伊春地区为黑龙江省花岗岩型铀矿化异常集中的区域,构造岩浆活动强烈,成矿地质条件优越。铀矿化主要产于印支期—燕山期花岗岩与古生代火山—碳酸盐岩沉积建造内外接触带,发育热液交代及热液充填型铀矿化,受接触带及断裂控制,与萤石化、赤铁矿化、黄铁矿化、绿泥石化等蚀变关系密切。通过对地层、岩体、构造、航放、遥感铁染异常等成矿条件进行分析,认为研究区具备较好的花岗岩型铀矿找矿前景,圈定一级远景区2片,二级远景区3片。
英文摘要:
      The Yichun area is the most concentrated area of the granite type uranium mineralized anomaly in Heilongjiang Province. The tectonic magmatic activity is intensive and the ore-forming geological condition is favorable in Yichun area. The uranium mineralization is mainly distributed within and outside the contact zone between the Indosinian-Yanshanian granite and Paleozoic volcanic-carbonate sedimentary rocks, and controlled evidently by contact zone and faults. The mineralization is closely associated with alterations of fluoritization, hematitization, pyritization and cloritization. The uranium mineralization are divided into two types, i.e., hydrothermal filling type and metasomatic type. According to the analysis of metallogenic conditions such as strata, magmatic rocks, structures, airborne radiometric interpratation and iron alteration information based on ETM image, it is predicated that there is great potential for prospecting granite type uranium deposit in the area and two prospecting target area with Grade I and three target areas with Grade II were outlined finally.
