川-滇-黔铅锌多金属成矿域是我国重要的铅锌分布区之一,该区具有铅锌矿床数量多、储量大、品位高等特点,备受学者关注。愈来愈多的学者研究发现,区内的铅锌成矿与构造关系甚为密切(韩润生等,2006,2010,2012,2014;Han et al.2007,2012);认为该区在印支晚期扬子地块西南缘发生强烈斜冲走滑,形成一系列冲断褶皱构造(带),驱动流体大规模运移,沿冲断褶皱构造带“贯入”成矿。
Chuan-Dian-Qian Pb-Zn polymetallic metallogenic area is one of the most important lead-zinc distribution areas in China. This area has the characteristics of many lead-zinc deposits, large reserves and high grade, attracting much attention from scholars. More and more scholars have found that the Pb-Zn mineralization in the area is closely related to tectonics (Han et al., 2006, 2010, 2012, 2014; Han et al. 2007, 2012) In the southwestern margin of the Yangtze block, strong oblique-strike-slip strike occurred, forming a series of thrust fold structures (belts), driving fluid migration on a large scale and forming a metallogenetic belt along the thrust fold.
