Research on the geological characteristics and ore-controlling factors of Kushuiquan gold mine in the northern margin of Qaidam basin
Kushuiquan gold mine is located in the PB-Zn-AU-Cu-Mn-coal metallogenic sub-belt of Xitie mountain-Buguote mountain in the northern margin of Qaidam basin.The ore body is controlled by northwest-southeast,northeast-southwest and nearly north-south trending fault structures.The host rock is early Silurian quartz diorite.The metal minerals of the ore are medium to low temperature combinations such as magnetite,pyrite,chalcopyrite,fibronite,goethite,malachite and azurite.The alteration of the surrounding rock in the near mine is characterized by sericitization and silicification,while that in the far mine is characterized by chloritization,epidotization,sericitiza-tion and carbonation.The gold mine is mainly controlled by faulted structures and diorite dikes.The prospecting indicators are fault structures,rock alteration and diorite veins.In summary,useful refe-rences for future research on the similar type of gold mine can be provided by conducting research on the controlling factors and prospecting indicators of Kushuiquan gold mine.
