冀东迁西群是我国已查明的比较老的太古界,对它的研究具有极为重要的意义。59—60年长春地质学院燕山队在本区首次填了1∶20万地质图,初步建立了该区老变质岩的层序。之后,河北省区测二队、华北所、长地院等单位在该区又做了大量工作,就地层划分分别提出了不同方案。八○年长地院对迁西群地层做了如下划分: 上部(马兰峪组):以黑云变粒岩为主夹斜长角闪岩; 中部(三屯营组):由二辉麻粒岩、斜长角闪岩、斜长辉石岩、黑云变粒岩组成薄层状互层; 下部(上川组):以二辉麻粒岩为主夹薄层状斜长角闪岩、浅色麻粒
Jidong Qianxi group to move is our country has been identified in the older archaic community, its research is of great importance. 59 - 60 years Changchun Institute of Geology Yanshan team in the area filled the first 1: 200000 geological map, the initial establishment of the sequence of the old metamorphic rocks in the area. After that, two units from Hebei Province, North China Institute, Longyuan Institute and other units in the area have done a great deal of work, put forward different plans for stratification. The 80-year-old court divided the Qianxun formation into the following categories: Upper part (Malanyu Formation): Mainly composed of black-mica granulites amphibolite; Central (Santunying Formation) Granulite, amphibolumite, plagioclase rock, black-grained metamorphic strata; the lower part (Shangchuan Formation): mainly composed of two-pyroxene granulite, amphibole amphibolite Light-colored granule
