摘　　要：锡林郭勒杂岩出露于华北地块北缘晚古生代褶皱带内,位于内蒙古东部锡林郭勒盟-西乌珠穆沁旗-巴林右旗一带,主要为细粒黑云母斜长片麻岩,斜长角闪片麻岩,磁铁石英岩,云母石英片岩,变质辉长辉绿岩,镁绿泥石透闪石岩,片麻状黑云母英云闪长岩。通过在野外研究,实测剖面以及岩石类型鉴别的基础之上,可将锡林郭勒杂岩划分为三套岩石组合:花岗岩类组合;基性-超基性岩组合;表壳岩组合。Xilingol metamorphic assemblage in the late Paleozoic fold belt in northern margin of north China massif, is located in the eastern Inner Mongolia, xilingol league area - west ujimqin - bahrain right flag area are mainly fine grained biotite plagioclase gneiss, long oblique Angle of gneiss, magnetite quartzite, mica quartz schist, metamorphic gabbro diabase, amphibolite magnesium chlorite, gneissic biotite tonalite. Through the study in the wild, the measured profile and rock type identification, on the basis of xilingol complex can be divided into three sets of rock combination： granite type combination; Basic - ultrabasic rock combination; Watchcase rock combination.
