Abstract

The characteristics of macrolithology, fabric and rare earth elements of the immediate host siliceous rocks from Gaolong Gold Deposit suggest that they are of hydrothermal sedimentary origin, not of fracture breaking-hydrothermal silicified origin. Siliceous rocks probably deposited in transitional area between the continental margin and ocean basin environment, but closed to the continental margin, according to rock chemistry, rare earth elements and trace element geochemistry.
