Summary:The Laurel Creek amphibolite is composed of subsets of the assemblage hornblende + chlorite + garnet + kyanite + staurolite + orthoamphibole + plagioclase (An47-An97) + quartz + ilmenite + rutile + pyrrhotite. These rare assemblages are believed to be the result of high-P metamorphism of moderate T, not of unusual bulk compositions. [J.A.Z.]
