The Qingmingshan magmatic Fe-Ni-Cu sulfide deposit is located in the southern margin of the Yangtze Craton, in the western part of the Proterozoic Jiangnan orogenic belt. Sulfide mineralization occurs as disseminated zones in a dike-like mafic body intruding Early Neoproterozoic meta-sedimentary rocks. The host intrusion can be further divided into an upper gabbronorite unit, a middle dolerite unit...
The Hongge layered intrusion (259.3±1.3Ma) is one of several mafic–ultramafic intrusions that host giant Fe–Ti–V oxide ore deposits in the ~260Ma Emeishan Large Igneous Province (ELIP), SW China. The Hongge intrusion consists of a lower olivine clinopyroxenite zone (LOZ), a middle clinopyroxenite zone (MCZ) and an upper gabbro zone (UGZ). Most of the 14 to 84m-thick and 300 to 1700m-long economic...
