LA-ICP-MS element maps (S, Fe, Pb, Ag, Sb, Bi, Tl, Te, Se, Cu, Zn, Cd, In, Sn, Co) of an equilibrium assemblage comprising coexisting galena (Gn), sphalerite (Sp), and chalcopyrite (Cp) (Hj13, Herja). Note the preferential concentration of Ag, Sb, Bi, Tl, Te, and Se in galena, and of Cd, In, Sn, and Co in sphalerite. Note also compositional zoning of all elements in galena, and of In (and to some extent Sn), in sphalerite. Relative concentrations of In, Sn, and Co in the three sulfides are in the order Sp &gt; Cp &gt; Gn. Ag and Sb are also noted within fractures at or close to the chalcopyrite-sphalerite contact. Mn, Hg, and Ga (not shown) are also preferentially incorporated in sphalerite. Scales in parts per million. (Color online.)

A. Distribution of polymetallic Cu-Fe-Au, Mo, Zn, and Pb deposits in the seven mining districts outlined in the Lower Yangtze river belt, east-central China (modified after Pan and Dong, 1999; Mao et al., 2006). B. Distribution of 140~125Ma magmatism and some major faults in the Lower Yangtze river belt (data supplied by Professor Jun Yan). The inner belt consists of high potassium calc-alkaline intermediate-acidic intrusive rocks, high sodium calc-alkaline intermediate-basic intrusive rocks, shoshonite, and A-type granite. “A” represents the A-type granites, which are symmetrically distributed along the Lower Yangtze river belt. The south belt consists of calc-alkaline rocks. The north belt also consists of calc-alkaline rocks, but it is less developed and more complicated than the other two belts (Xing, 1999). TLF = Tancheng-Lujiang fault, XGF = Xiangfan-Guangji fault, YCF = Yangxing-Changzhou fault.
