摘要: 苏鲁超高压榴辉岩的成因一直是一个令人困惑的问题。本文通过对榴辉岩的进变质作用——榴辉岩相向石榴石岩相转变的初步研究,为苏鲁榴辉岩带的地幔转换带(高压可达10GPa)成因提供了最初的证据。

Abstract: The genesis of the Jiangsu-Shandong ultrahigh-pressure eclogites has so far remained a puzzling problem.The preliminary study of the prograde metamorphism of the eclogites as represented by the eclogite-garnetite transformation in this paper, provides some initial evidence for their origin as a mantle transition zone (pressure up to 10 GPa).
