AN style="FONT-FAMILY: ’Times New Roman’,’serif’" lang=EN-US>The gold deposit belt of black rock series of Lower Silurian Meiziya Formation in Northern Shiquan-Hanyin is tectonically located in the north margin of Niushan Old Land in the west of South Qinling Orogenic Belt. Based on the lithological assemblage characteristics, it is divided into six lithologic members and four ore-bearing sub-layers. The characteristics of hydrogen and oxygen isotopes indicate that the aqueous media of the ore-forming fluid are mixed water containing mainly metamorphic-hydrothermal solution and atmospheric precipitation. The REE features reveal that the material source of gold deposits is similar to the Devonian sedimentary rocks in Qinba area.
