(2) the Cretaceous pelite unit had undergone progressively increasing degrees of partial melting with the proximity of the Goat Ranch granodiorite; ②变泥质岩发生了递进部分熔融,表现为离羊圈花岗闪长岩岩体的距离越远,部分熔融程度越低;
Granodiorite is a phaneritic-textured intrusive igneous rock similar to granite, but containing more plagioclase feldspar than orthoclase feldspar. According to the QAPF diagram, granodiorite has a greater than 20% quartz by volume, and between 65% to 90% of the feldspar is plagioclase. A greater amount of plagioclase would designate the rock as tonalite.
