超硅石榴子石是一种典型的超高压矿物,其稳定存在的压力>5GPa.在新疆北部扎河坝-阿尔曼泰早古生代造山带扎河坝蛇绿岩岩块的石榴辉石岩中首次发现了超硅石榴子石及同样具有超高压特征的超钛石榴子石.研究显示,所发现的超硅石榴子石和超钛石榴子石的形成深度不小于300km,它们的寄主岩石-石榴辉石岩是与洋壳超深俯冲有关的超高压变质岩.研究同时显示,扎河坝-阿尔曼泰早古生代造山带的形成与古亚洲洋洋壳超深俯冲有关.
Ultra-silicon garnet is a typical ultrahigh-pressure mineral with a stable pressure> 5 GPa. In the garnet pyroxenite of the Zhaheba ophiolite block in the Zhaheba-Almante orogenic belt of northern Xinjiang, The first discovery of super-silicon garnet and the same ultra-high pressure super-titanium garnet characteristics.Studies show that the found super-silicon garnet and super-titanium garnet formation depth of not less than 300km, their host rock - pomegranate Pyroxene is an ultrahigh-pressure metamorphic rock associated with the ultradeep subduction of the oceanic crust.The study also shows that the Early Paleozoic orogenic belt of the Zaheba-Armantai is related to the ultra-deep subduction of the oceanic crust of the ancient Asian continent.
