Mantle Plumes and Ore Genesis in Zhongtiaoshan Area
详细信息   
摘要

    

Geophysics characteristics indicate that Neoarchean-Proterozoic mantle plume were developed in the Zhongtiaoshan region. Metallogeny here shows co-existence pattern of four ore generations. Temporally, the ore formation is close to magma intrusion. Spatially, most deposits occur symmetrically along two crosscutting sets of faults in the rift zone. Ore-forming elements and mineral components and the ore-forming temperature decrease outward from the center.  Before Neoarchean the Cu-rich Yangtze Plate underthrusted under North China Plate leading to thickening of crust at Zhongtiaoshan rift area and abundant ore material field. Pulse rising of the mantle plume carried hydrothermal fluid upward and extracted Cu and Zhongtiaoshan area becomes the copper ore deposit-clustered area.
