      American Mineralogist 92 (2007) 57-63
      First in situ X-ray diffraction identification of coesite and retrograde quartz on a glass
      thin section of an ultrahigh-pressure metamorphic rock and their crystal structure details
      Locality: Yangkou meta-igneous complex in the middle part of the Sulu UHP terrain, eastern China
      Note: Sample is on a thin section
