The South China tectonic block (SCB) is bounded to the north by the Qinling-Dabie orogenic belt, and to the west and southwest by the Tibetan and Indochina blocks. The Permian mafic rocks (e.g. diabase and basalt) are concentrated in the Shijia of western Guangxi, economically significant gold mineralizations are genetically associated with these mafic rocks (Fig.1). However, the causes of magmatism and related gold deposit background are controversial. Here, we present the comprehensive major element, trace element data of orebearing mafic rocks with previous published data, detailed discuss the geochemical characteristics of the bulk of Shijia mafic rocks and their petrogenesis.
