在苏-鲁超高压变质带(UHPMB)的岚山头含蓝晶石榴辉岩发现柯石英包体,这使蓝晶石的稳定域延伸至2.4GPa之上。作为中国东部一条重要的超高压变质带,主要是在印支期,当初始欧亚板块与古太平洋板块作用过程中黄海地体向胶东—苏东北地体强烈挤压引发的A-型俯仲的产物。该带是由3～4个向东突出的弧形构造所组成,如威海(NW走向)—荣城(SN走向)青岛—五莲(NE走向)弧等;而岚山头榴辉岩正处于日照—赣榆弧的顶部。苏—鲁榴辉岩带延长约
The coesite inclusions were found in the Lan-Shan head-containing kyanite eclogites of the Su-Lu UHP metamorphic belt (UHPMB), extending the stable domain of kyanite above 2.4 GPa. As an important UHP metamorphic belt in the eastern part of China, mainly during the Indosinian A-type subduction caused by strong extrusion of the Yellow Sea terrain to the Jiaodong-northeast terrane during the initial Eurasian and Paleo-Pacific plates Of the product. The belt is composed of 3 to 4 arc-shaped structures that protrude to the east, such as the Weihai (NW strike) - Rongcheng (SN strike) Qingdao-Wulian (NE strike) arc, etc; and the Arashiyama eclogite is in Rizhao - Ganyu arc at the top. Su-Lu eclogite belt extension of about
