摘要
新疆东天山地区蓟县系原卡瓦布拉克群为一套岩性复杂、变质程度差异很大的变质岩系,通过大黑山幅1∶25万区调的调查研究将其进行了解体,根据岩石组合,变质程度及所含叠层石的组合重新厘定了层序,它包括了未分太古界、下元古界兴地塔格岩群(Pt1x)、长城系杨吉布拉克岩群(Chy)、蓟县系爱尔基干岩群(Jxa)和青白口系帕尔岗塔格岩群(Qmp).同时对各岩群的岩石组合、变质、变形进行了区域性的对比研究.
The original Kawabulake group of east Tianshan in Xinjiang is a set of metamorphite system of complex lithology and obviously different metamorphic grade. According to Daheishan 1∶250000 regional geological survey and rock assemblage metamorphic degree and the combination of stromatolite ,strata sequences of this region are rearranged. They include undivided Archean, Xingditage rock suite of late Proterozoic era, Yangjibulake rock suite of Changchengian system, Aierjigan rock suite of Jixianian system, and Paergangtage rock suite of Qingbaikouian system. At the same time, we did the regional contrast research on rock assemblage, metamorphite and deformation of every rock suite.
