继车自成等在阿尔金山东段贝克滩一带发现高压变质岩石之后,我们又在其西段江格萨依南确定了一套榴辉岩。该榴辉岩与石英石榴单斜辉石岩相伴生,有些已退变为榴闪岩。它们呈透镜体状出露于区内元古界中深变质岩系之中,向东断续可追索到茫崖石棉矿西北,全长约200km(图1)。
Following the discovery of high-pressure metamorphic rocks in the area of Baker Beach in the eastern part of the Altun Mountains following the completion of a car, we again established a set of eclogites in the Jianggassanan of the western segment. This eclogite is associated with quartz phengu clinopyroxenite, some of which have been degenerated into lorphylite. They are lenticularly exposed in the metamorphic mid-deep metamorphic rocks in the area, and can be traced back to the northwest of the Mangya asbestos mine in the east, with a total length of about 200 km (Figure 1).
