Abstract
The granulite xenoliths are first found in Yingfengling pyroclastic rocks of Leizhou region, Guangdong Province. Of them high-pressure garnet granulite xenolith found is very sparse in China. Garnet granulite is different from pyroxene granulite in mineral assemblage and composition.P-T calculation shows that garnet granulite was formed at 1130–1160°C and 1.4–1.7 GPa, and pyriclasite at about 800°C and 0.65–0.80 GPa. High xenolith-derived paleogeotherm indicates Cenozoic rifting in Leizhou area. Granulites with varied mineral assemblages were formed at different depths by the metamorphism of the underplated basaltic melt.
