摘要
鄂拉山构造带区域构造复杂,岩浆活动发育,成矿背景良好,三叠纪鄂拉山组地层是研究区内主要的含矿岩层。北西—北北西向断裂构造是区内重要的导矿、控矿构造,矿床属火山喷发期后热液型矿床或次火山岩有关的热液型矿床。矿体露头是重要的找矿标志,和矿化体关系比较密切的构造是北西向、北东向断裂构造蚀变带,该两组断裂构造是重要的间接找矿标志,研究结果对以后的地质找矿具有很重要的指导意义。
The regional structure of the oraishan tectonic zone is complex,and magmatic activity is developed.The metallogenic background is good,and the Triassic oraishan formation is the main ore bearing strata in the area.The North West to North NNW fault structure is an important ore conducting,and ore controlling structure is in the region.The deposit belongs to the hydrothermal ore deposit related to the hydrothermal ore deposits or subvolcanic rocks after the volcanic eruption period.The outcrop of ore body is an important ore finding symbol.North West and North East trending fault in tectonic alteration zone is closely related to the mineralized body.The two groups of fracture structures are important indirect prospecting marks.The results will have important guiding significance for the future geological prospecting.
