自然界中铝辉石可以看成无铝辉石中石榴石的固溶体,高压下可以使铝辉石→石榴石+贫铝辉石,本文采用天然样品进行辉石-石榴石相转变超高压实验研究,解释石榴石橄榄岩的成因。
The natural pyroxene can be regarded as the solid solution of the garnet in the Al-free pyroxene, which can make the aluminopyroxene → garnet + poor aluminopyroxene under high pressure. In this paper, the natural samples were used to study the pyroxene-garnet phase transition ultrahigh pressure , Explain the causes of garnet peridotite.
