Structure, Alteration, and Fluid Inclusion Study on Deep and Surrounding Area of the Dongping Gold Deposit, Northern Hebei Province, China
详细信息   
摘要

    

The gold deposits in Dongping area, northern Hebei Province are firstly found among the alkaline complex in China. These gold deposits are often recognized as alkaline rock-related gold deposits because of surrounding rocks. Alterations and mineralization of the Dongping gold deposit can be divided into four stages. They are 1) feldspar-quartz veins stage, 2) pyrite-white quartz stage, 3) sulphides-smoky gray quartz vein stage, and 4) late carbonate stage. It is more reasonable to consider the gold deposit in the Dongping area as intrusion-related gold deposits, based on geological setting, hydrothermal alteration, ore mineral assemblage, and characteristics of fluid inclusions.
