Geochemical Constraints on Genesis of the Xinqiao Cu-Au-S-Fe Deposit in the Tongling Ore-Cluster Field, Middle-Lower Yangtze Metallogenic Belt

The Tongling ore-cluster field, South Anhui Province is an important metallogenic base for Cu-Au-Fe-S mineralization in the Middle-Lower Yangtze Metallogenic Belt. The large Xinqiao Cu-Au-Fe-S deposit, situated the east of Tongling city, is a typically representative in this ore -cluster field. It locates at the intersection of the northern limb of the NNE-trending Shujiadian anticline and the
