The Wenjiangsi ore deposit in the eastern extension of the oft-com:office:smarttags" />West Qinling orogenatic belt is a newly-discovered gold deposit hosted in a Triassic (carbon-bearing) calcareous slate sequence. Lenticular ore bodies and ore spots are characterized by disseminated mineralization with Au-As-Sb-Hg-Pb-Zn low-temperature assemblages. From the ore and argillaceous slate to granite veins, Al₂O₃ and alkaline components (K₂O + Na₂O) increase, accompanied by decreasing of CaO and K₂O/Na₂O.Trace elements (e.g., As, Bi, Co, Ni, Cu, W, V, Tu and U) and REE patterns (ΣREE, LREE/HREE) of disseminated ores are similar to things of hosted calcareous slates, indicating that metals were derived from hosting strata instead of from magmatic intrusions. The discovery of the Wenjiangsi gold deposit makes it possible for further eastward extension of the West Qinling Triassic sequence.
