Abstract
Coesite inclusions, together with omphacite, jadeite, garnet and phengite i nclusions, were identified in zircons separates from almost all gneissic co re samples of pre-pilot drillhole CCSD-PP2 by the Laser Raman spectroscopy and the cathodoluminescence method. These data indicate that gneissic rocks consisting of paragneisses and orthogneisses ubiquitously experienced UHP metamorphism. This research may be of great significance for an in-depth st udy of the subduction-exhumation mechanism of the Sulu UHP metamorphic belt and selecting the drilling site for the Chinese Continental Scientific Dri lling Project.
