华南中生代发生了大规模的岩浆活动,形成了大量与花岗岩有关的钨、锡、钼、铋矿床。燕山期花岗岩的成矿作用已获得了较为充分的研究,而印支期花岗岩成矿作用也逐渐为人们所关注。目前发现的与印支期花岗岩有关的矿床的成矿元素组合主要以W(如油麻岭、邓阜仙、高岭),Sn(如荷花坪)和W-Sn(如仙鹅塘)为主(蔡杨等,2013;程顺波等,2013;郭春丽等,2011;张迪等,2015;章荣清等,2010)。而云头界矿床是迄今为止在南岭地区发现的唯一与印支期花岗岩有关的W-Mo矿
Large-scale magmatism occurred in the Mesozoic Mesozoic in southern China, forming a large number of tungsten, tin, molybdenum and bismuth deposits related to granite. The mineralization of Yanshanian granite has been more fully studied, and the Indosinian granite metallogenesis has gradually attracted people’s attention. The presently discovered ore-forming elemental assemblages of the Indosinian granitoids mainly include W (such as Yau Ma Ling, Deng Fu Sin, Kaolinite), Sn (such as Hehua Ping) and W-Sn Main (Cai Yang et al., 2013; Cheng Shunbo et al., 2013; Guo Chunli et al., 2011; Zhang Di et al., 2015; Zhang Rongqing et al., 2010). The Yuntoujie deposit is the only W-Mo mine related to Indosinian granites discovered so far in the Nanling area
