阔克吉勒嘎金矿处西昆仑山西段腹地、帕米尔高原萨雷阔勒岭一带,在构造分区上依据陕西地质调查院2010年1∶5万区域工作成果,工区地层区划属西藏-三江地层大区-羌塘地层区-喀喇昆仑地层分区-塔什库尔干-甜水海地层小区.区内出露的志留系地层为浊流沉积建造,该地层与造山型金矿床关系密切,阔克吉勒嘎金矿为与韧性剪切带有关的破碎蚀变岩型或破碎蚀变岩型金矿床,矿体赋存于下志留统温泉沟群碎裂状绿灰色硬绿泥(褐铁矿化、菱铁矿)绢云千枚岩中,该矿经过近年来的地质工作,深部找矿取得突破,发现多个盲矿体,且品位较富,认为该矿具有较好的找矿潜力.
Exploration of Geological Characteristics and Genesis of Kuokjilega Gold Mine
The Kuokjilga Gold Mine is located in the hinterland of the western Kunlun Mountains and the Sarekuole Mountains of the Pamirs.According to the 1:50000 regional work results of the Shaanxi Geological Survey Institute in 2010,the stratigraphic division of the work area belongs to the Xizang Sanjiang Stratigraphic Region Qiangtang Stratigraphic Region Karakorum Stratigraphic Subregion Tashkurgan Tianshui Haiti Subregion.The exposed Silurian strata in the area are constructed by turbidite sedimentation,which is closely related to orogenic gold deposits.The Kuokjilega gold deposit is a fractured altered rock type or fractured altered rock type gold deposit related to ductile shear zones.The ore body is found in the fractured green gray hard green mud(limonite,siderite)sericite phyllite of the Wenwengou group in the Lower Silurian.After recent years of geological work,breakthroughs have been made in deep ore exploration,and multiple blind ore bodies have been discovered with relatively high grades.It is believed that the ore body has good prospecting potential.
