The Baguamiao gold deposit in a sort of mesothermal hypothermal carbonate type gold deposit. Quartz, one of the major gangue minerals, is closely related to gold mineralization. According to modes of occurrence, auriferous quartz veins might be divided into three types:(1) bedding quartz veins;(2) ferriferous dolomite quartz veins;(3)quartz veins along NE trending joints. These types show certain differences in compositional characteristics of trace elements and rare earth elements and were formed respectively at different ore forming stages of gold, being evolutional products of gold in the process of ore forming process. Thermometric measurements of inclusions in quartz have provided evidence for mesothermal hypothermal origin of the Baguamiao gold deposit.
