对山东高压-超高压变质带的几点看法——程裕淇院士野外考察记

SOME OPINIONS ABOUT HIGHULTRAHIGH PRESSURE METAMORPHIC BELT IN SHANDONG

摘要:

通过对山东高压超高压变质带的考察，初步认为：榴辉岩的最后隆升时代为燕山期；含硬玉石英岩＋榴辉岩＋（透辉石）大理岩组合说明表壳岩经历了高压超高压变质作用；该带晋宁期长英质片麻岩花岗岩广泛出露；在其北部麻粒岩和榴辉岩密切伴生。

After visiting the highultrahigh pressure metamorphic belt in Shandong,some opinions about it stated by professor Cheng Yuqi,an academician of Chinese academy of sciences:the last lifting period of eclogite belongs to Yanshan stage;the combination of jadeitebearing quartzite, eclogite and (diopside)marble shows that the supracrustal rock experienced highultrahigh pressure metamorphism; felsic gneissgranites of Jinning stage widely overcropped in this area;gneiss and eclogite occur accompaniedly in its north...
