新疆巴尔鲁克西段基性-超基性岩带中金矿找矿潜力分析
Prospecting Potential of the Gold Deposit in the Basic-Ultrabasic Rocks, West Baerluke Mountain, Xinjiang
-
摘要: 西准噶尔西缘巴尔鲁克山西南部存在近东西向的也节拜蛇绿混杂岩带, 带内基性-超基性岩发育, 基性-超基性岩与南北围岩接触带内构造发育并具强烈蛇纹石化, 在其中及附近围岩中发现多处金异常和多条金矿化体。现有工作及找矿实践表明, 也节拜蛇绿混杂岩带西段发育的金矿化体与带内基性-超基性岩在空间上密切相伴, 成因上密切相关。该特点与世界上典型的基性-超基性岩型金矿相似, 可以应用基性-超基性岩型金矿的成矿理论指导本区找矿。根据区内矿化体特征、成矿条件, 结合区域物化探特征和成矿规律, 应用基性-超基性岩型金矿的成矿理论综合分析认为:也节拜矿区内基性-超基性岩与南北围岩接触带具强烈蛇纹石化地段、基性-超基性岩中构造发育且蛇纹石化强烈部位、蛇绿混杂岩中的韧性剪切带及附近构造部位均为有利的找矿区域;也节拜蛇绿混杂岩带东部和苏云河蛇绿混杂岩带具有基性超基性岩金矿的找矿潜力。Abstract: Baerluke Mountain is located in the western margin of west Junggar. There is a nearly east-west ophiolite melange belt named Yejiebai in southwest Barluke Mountain. The basic-ultrabasic rocks were well-developed in the belt. Lots of gold anomaly and mineralized body have been discovered in the basic-ultrabasic rock and the surrounding rock. Existing work and prospecting practice show that the spatial occurrence of gold mineralized body is closely related to basic-ultrabasic rock in the west of Yejiebai ophiolite melange belt and the orebody characteristics are similar to the typical basic-ultrabasic rock type gold deposits. By studying the metallogenic theory of basic-ultrabasic rock type gold deposits, combined with the characteristics of mineralization bodies, metallogenic conditions, geophysical and geochemical features, and ore-forming regularity, the authors hold that the contact zone with well-developed serpentinization of basic-ultrabasic rocks and their south-north wall rocks, basic-ultrabasic rock with well-developed tectonic and serpentinization, the ductile shear zone in the ophiolite mélange and the structural position nearby are all favorable mineralization regions. The basic-ultrabasic rock type gold deposits are prospective in the eastern Yejiebai ophiolite melange belt and Suyunhe ophiolite melange belt.
