Eclogites, orthogneiss, paragneiss, schists and quartzites of the Sulu ultrahigh-pressure (UHP) metamorphic terrane, exposed in a roadcut in the Qinglong hills (Qinglongshan). Four stages of metamorphism were recognized by combining petrographic observations and compositions of minerals from various UHP rocks: prograde epidote-amphibolite facies, UHP coesite eclogite facies, post-UHP quartz eclogite facies, and retrograde amphibolite facies metamorphism.
NOTE: The grid reference is centered on the area.
