Qinling gneiss domes and implications for tectonic evolution of the Early Paleozoic Orogen in Central China

The Qinling arc terrane (QAT) at the southern margin of the North Qinling Early Paleozoic orogen, Central China, is composed of gneiss domes overridden by cold allochthon nappes. The gneiss domes are characterized by migmatitic and plutonic cores of granite or gabbro and overlying upper amphibolite to granulite facies metamorphic sequences with pervasive injection of leucogranitic veins. The gneiss domes display a high temperature domal...
