华南构造块（SCB）北部以秦岭-大别造山带为界，西部和西南部以青藏高原和印度支那地块为界。二叠纪镁铁质岩（辉绿岩、玄武岩等）集中分布在桂西石家地区，具有经济意义的金矿化与这些镁铁质岩有成因关系（图1）。然而，岩浆作用的成因和相关金矿床背景存在争议。在此，我们结合以往发表的资料，全面介绍了含矿基性岩的主量元素、微量元素数据，详细讨论了石家基性岩体的地球化学特征及其岩石成因。
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.
