南岭钨锡成矿作用几个关键科学问题及其对区域找矿勘查的启示

Several Crucial Scientific Issues Related to the W-Sn Metallogenesis in the Nanling Range and Their Implications for Regional Exploration: A Review

南岭地区中生代多期次、大规模的钨锡多金属成矿作用造就了全球最为重要的钨锡成矿带。本文结合最新的相关研究成果及找矿突破,系统综述了南岭地区成岩成矿作用时空分布格局、成矿花岗岩的矿物学、地球化学特征和矿床模型的研究进展及存在问题,并在此基础上初步提出了该区深部找矿方向,以期推动区域找矿勘查取得新突破。

Multiple,large scale Mesozoic W-Sn polymetallic metallogenic events in the Nanling Range generate one of the most important W-Sn metallogenic belts in the world. Here,combined with the latest research advances and progresses on mineral exploration in the Nanling Range,we conduct a systematic review on the spatial-temporal distribution of the Mesozoic W-Sn polymetallic deposits and related granitic plutons,mineralogical and geochemical characteristics of W-Sn-bearing granites,and prospecting models for W-Sn mineralization in the Nanling Range. Based on the above,we analyze potential prospecting target in deep W-Sn polymetallic deposits in the Nanling Range,in order to promote regional mineral exploration.
