“…On the other hand, although the most of these Pb-Zn deposits in the SYG province are clearly epigenetic, different opinions have been proposed on the ore genesis of them. These hypotheses include: (i) the Mississippi Valley-type (MVT) deposit related to basin brine (Zheng and Wang, 1991;Zhou et al, 2001;Wu et al, 2013;Zhang et al, 2015), (ii) the Permian Emeishan mantle plume-related deposit (Xie, 1963;Huang et al, 2003Huang et al, , 2010Xu et al, 2014), and (iii) the unique SYG-type deposit that are different from the typical MVT deposit Zhou et al, 2013aZhou et al, -c, 2014b. Recently, studies of Cd, Ge and Zn isotopes Zhou et al, 2014a,b;Meng et al, 2015), and in situ trace elements of sphalerite (Ye et al, 2011) have indicated that the ore genesis of these Pb-Zn deposits in the SYG province is Zhou et al, 2013a).…”
