| مستخلص: | The breccia pipe has been intensely altered and shows apparent alteration zoning, with Au mineralisation closely related to silication and adularisation. Electrum is the dominant mineral and mainly occurs in arsenopyrite. The primary mantle-normalised rare earth and trace element patterns of the breccia show enrichment of LREE and K and depletion of Eu, Ti, Sr, Ba, Th, U, in conformity with the features of non-mature normal arc granites on the continental margin. The homogenisation temperatures of fluid inclusions in quartz indicate that Au mineralisation took place mainly at temperatures of 150-180 degrees C and 225-390 degrees C. The deposit is of the epithermal-mesothermal type and was formed in the Early Yanshanian period.
