摘要
乌拉嘎金矿床位于吉黑地槽褶皱系的北部,佳木斯隆起与张广才岭褶皱带接触部位的北端。北北东向的乌拉嘎断裂带,将本区分为中部乌拉嘎断陷,东部鹤岗凸起和西部结烈凸起三部分。笔者根据资料、野外工作及室内研究,阐述了区域成矿地质背景,总结了矿区地层、控矿构造、岩浆岩、矿体、和围岩蚀变等矿床地质特征,并初步证实该矿床类型为低温热液裂隙充填交代型金矿,为本区今后找矿方向的确定提供了基础地质参考依据。
Wulaga Gold Deposit locate in the north part of Jilin and Heilongiiang geosynclinals fold belt, and the north of contacting section between Jiamusi uplift and Zhangguangcai fold belt. The area is divided to three part of Wulaga depression, Hegang lift in eastern and Jielie lift in western by north east WUlaga fault belt. Based on the predecessor＇s research data, and the research results of field work and home analysis, the regional geologic mineralizing background has been stated in the paper, and the features of stratum, ore - controlling structure, igneous rock, ore body and Wall - rock alteration have been summarized. It is verified that the origin of this gold deposit belongs to cryogenic hydrothermal type concern with fissure filling and alteration, and the conclusion provides the basic geologic reference to determine the exploration direction in future.
