青海土房子南地区金多金属矿地球化学特征及找矿远景

Geochemical characteristics and prospecting prospect of gold polymetallic deposits in the southern area of Tufangzi,Qinghai Province

青海土房子南金多金属矿处于祁漫塔格-都兰华力西期铁、钴、铜、铅、锌、锡硅灰石(锑、铋)成矿带,区内构造活动强烈,断裂构造以与昆北断裂平行展布的次级断裂为主,具有较好的含矿热液通道和储矿空间。通过1∶5万水系沉积物工作,采用衬值法圈定出4处衬值异常,综合分析区内地质地球化学特征,查明区内元素的分布规律和组合特征,重点选择HS132Au(W Mo As Co)地球化学异常,进行重点查证并圈定了四条蚀变带。研究表明,该区具备良好的成矿地质条件,成矿潜力较大,具有良好的找矿前景。

The southern area of Tufangzi polymetallic mine is located in the Qimantage-Dulan Warissi Iron,Cobalt,Copper,Lead,Zinc,Tin Wollastonite( Antimony,Bismuth) Metallogenic Belt,strong tectonic activity in the area,the fault structure is mainly secondary faults that run parallel to the Kunbei fault,and has good ore-containing hydrothermal channels and storage space. through the work of 1 ∶ 50000 sediments in the water system,four liner anomalies were delineated using the liner method. The geological and geochemical characteristics of the area were comprehensively analyzed,and the distribution and combination characteristics of elements in the area were identified. The HS132 Au( W Mo As Co) geochemical anomalies,key verification and delineation of four alteration zones. Studies have shown that the area has good metallogenic geological conditions,great mineralization potential,and good prospecting prospects.
