摘 要:正 The Chinese Continental Scientific Drilling (CCSD) located near Maobei village, about 17 km southwest of Donghai, is targeted to drill a 5000-meter-deep main hole penetrating a tectonic slab of UHP metamorphic rocks. This project provides an advantageous and rare chance of collecting UHP rock samples continuously from the subsurface. The 0-2050 m of the CCSD-main hole consists of eclogite, orthogneiss, paragneiss, ultramafic rock and minor schist and quartzite. Eclogites are the principal lithological type, and mainly occur at
