作者1982年对内蒙古潮格旗以北伊很查汗庙-勃尔和地区进行了野外考察,并做了大量的室内工作。通过对23个变质白云母的X射线衍射和化学分析,3对黑云母-石榴子石矿物对的元素分配系数及4个闪石类矿物的化学成分的研究,认为该变质带变质压力大约1.5-4kbar,变质温度约470-550℃,应属于低压高温变质带。该带中的闪石矿物应为钙闪石类。没有发现蓝闪石片岩带。
In 1982, I inspected Zhanshan Temple - Boer and the area in the north of Chaog Banner, Inner Mongolia, making field trips and doing a lot of indoor work. Based on the X-ray diffraction and chemical analysis of 23 metamorphic micas and the study on the elemental partition coefficients of 3 pairs of biotite-garnet pairs and the chemical composition of 4 amphiboles, it is considered that the metamorphic pressure is about 1.5 -4kbar, metamorphic temperature of about 470-550 ℃, should belong to low pressure and high temperature metamorphic belt. The amphibole minerals in this belt should be goethite. No glaucophane schist belt found.
