| 摘 要： | <正> 内蒙古自治区二连浩特以东,自二道井经巴音敖包、包日汗、红格尔庙至锡林浩特一带(以下简称集二线北带),下古生代的温都尔庙群呈北东东向断续分布(图1)。它们产出在构造地质学上著名的“蒙古弧”东翼,习惯上多称为内蒙古华力西褶皱带。我们同意将温都尔庙群出露区划为加里东优地槽褶皱带的意见。温都尔庙群岩石主要为细碧岩、块状绿泥闪帘石岩、绿泥闪市片岩、石英千枚岩(片岩)夹变质碧玉岩、石英岩以及磁铁赤铁石英岩，常伴有基性、超基性岩体的侵入。岩层变形强烈，发育有不同级别和不同型式的褶皱及断裂。1978年，我们在研究温都尔庙群层序及铁矿分布规律时，重点研究了包日汗地区的褶皱构造。

| Abstract: | The metamorphic rocks of the lower Palaeozoic Wenduermiao Group ofthe Baorihan region, Neimonggol, have suffered intense and complicated morphological disturbances. By measuring the plicated structure on the schistosity planes of both phyllite and schist for more than ten thousand times,we have gained an insight into the characteristics of spatial variation of thedirection and angle of plunging of the folding axes and are able to distinguish different generations of the folds, thus pointing out the various stages of the Caledonian strutural cycle that Wenduermiao Group has undergone, and a structural sequence composed of three generations has undergone, and a structural sequence composed of three generations has thus been established. |
