中国矽卡岩矿床找矿新进展和时空分布规律
New progress in prospecting for skarn deposits and spatial-teporal distribution of skarn deposits in China
摘要
Abstract
In the past decade,notable progress has been made in the discovery and exploration for skarn deposits in China.The discovery and exploration of ore deposits include more than 10 large Cu-(Au)-polymetallic skarn deposits in the Gangdise ore belt,Bangong-Nujiang ore belt,Tibet;many Fe polymetallic skarn deposits in the Qimantag ore belt,Qinghai;some large concealed skarn deposits in eastern China,such as Baijian iron deposit in Hebei Province,Zhuxi W-polymetallic deposit in Jiangxi Province,Xitian W-Sn deposit in Hunan Province,and Shangfang tungsten deposit in Fujian Province;some large iron skarn deposits related to marine volcano-intrusive activity in western Tianshan Mountains of Xinjiang.In addition,the Baiganhu,Shadong and Taergou large tungsten skarn deposits of Xinjiang and Gansu have also been discovered and explored.A lot of new isotopic chronologic data of the main skarn deposits in China suggest that the metallogenic ages include Proterozoic,Palaeozoic,Mesozoic,and Cenozoic.Among them,the most important is Mesozoic Yenshanian ages.As forspatial distribution of skarn deposits,Zhao et al.,(1990) divided the mineralization into 14 metallogenic belts,with the majority distributed in the activated region of the North China Craton and orogenic belts in East China,which constitute a part of the Circum-Pacific metallogenic belt.Owing to the effort of Chinese geologists,the exploration for skarn deposits in the Tibet,Qinghai,and Xinjiang has achieved remarkable success,which results in the addition of four ore-skarn belts:i.e.,Gandise ore belt,Bangong-Nujiang ore belt in Tibet,Qimantag ore belt in Qinghai,and Western Tianshan ore belt in Xinjiang.关键词
