新疆清水泉铜矿地质特征及成矿期次探讨

清水泉铜矿床位于新疆东准噶尔地区卡拉麦里成矿带西段，产于铜背景值较高的火山岩-安山岩中。卡拉麦里深断裂呈NWW-EW向自区内北侧穿过，带内岩石均已发生变形、变质，与近EW向次级构造及裂隙构成导矿和容矿空间。岩浆活动经历华力西早、中、晚多期次侵入，超基性岩、黑云母花岗岩、更长花岗岩、霏细斑岩及火山岩广布区内，构成特定岩浆建造与矿床的时空联系及多期次成矿物质的叠加。铜矿（化）体赋存于蚀变安山岩中，与层位、构造和岩浆活动密切相关，并严格就位于次级网脉状构造和裂隙中，矿化与黄铜矿化、黄铁矿化密切相关，并接受后期石英闪长玢岩脉的成矿叠加。细脉发育部位，矿化富集增强。

Discussion on the Metallogenic Regularity and Mineralization of Qingshuiquan Copper Deposit,Xinjiang Province

Qingshuiquan copper deposit located in Calamaili mineralization belt of East Junggar district in Xinjiang,it produced in volcanic rock and andesite which had higher copper background value.Calamaili deep fault(NWW-EW) cross along the north of the district,rocks in this fault belt had deformed and metamorphosed.EW secondary structure and fracture become passageway and host space of the ore.Magmatic activity experiences multi-periodic intrusion and eruption in early,middle and later Variscan.Ultrabasic rock,biotite granite,felsophyre and continental lava in the district formed specified magmatic formation which related with space-time of deposit,also with superaposition of multi-phase ore-forming mineral.Copper orebody hosted in meta-andesite,it had close relationship with position,structure and magmatic activities,and deposited orderly in secondary net-veined structure and fracture,its mineralization had certain relationship with chalcopyrite and pyrite mineralization,and overprinted succeeding quartz-diorite-porphyrite vein;mineralization enriched in well-developed vein lets.
