GEOCHEMISTRY OF THE BAOSHAN-TAOXING ECLOGITE IN THE MIDDLE SECTION OF SULU OROGENIC BELT

The Baoshan-Taoxing eclogite scatters in the granitic gneisses in the middle section of Sulu orogenic belt. With study on the major element, trace element and rare earth element geochemistry, as well as the mineral chemistry of garnet, it is concluded that the protolith of the eclogite is island arc tholeiite (IAT) derived from metamorphic crust and experienced HTP metamorphism along with its wall rock.
