铜陵-池州地区水系沉积物测量地球化学特征及找矿方向
GEOCHEMICAL CHARACTERISTICS AND ORE-SEARCH TARGETING IN TONGLING-CHIZHOU AREA OF ANHUI PROVINCE BASED ON STREAM SEDIMENT SURVEY
摘要
Abstract
Based on the 1 ∶ 200,000 stream sediment survey along the Yangtze River Fe, Cu, Au polymetallic ore-forming belt, the authors made a preliminary study of the geochemical anomaly characteristics in Tongling-Chizhou area. Factor analysis was employed for the elements, and the ore-forming elements assembly was determined. The ore-forming elements anomalies assembly was used to make geochemical division and, as a result, geochemical anomalies were delineated. Based on a comparative study of geological backgrounds and geochemical conditions, the authors conducted similarity analysis of the typical deposits in Tongling area and forecast Chizhou pros-pecting area. In consideration of the strata, structure, intrusive rocks and mineral resources in this area, the authors hold that it is fea-sible to use the ore-forming elements anomalies for geochemical division, which can effectively reflect anomalies caused by mineraliza-tion and highlight the mineralization information. Based on an analysis of the coupling between the similarity value calculations of the samples and the similarity graph of the typical deposit, the authors hold that Meijie Town in southern Chizhou City, the east side of Qingyang County, and the periphery of the Tongshan copper mine are most favorable areas in search for Cu polymetallic deposits.关键词
