| 摘 要： | 近年来,对中亚造山带中是否存在微地块有诸多不同看法,其中对广泛出露的锡林郭勒杂岩的时代和原岩认识存在较大的分歧。经大比例尺填图和详细露头解剖发现,它囊括了不同岩类、不同变质程度、不同构造样式和形成时代的地质体。文中建议将其解体,对其中被厘定的表壳岩命名为＂锡林浩特岩群＂,这是一套达到角闪岩相变质的夹有火山岩和磁铁石英岩...

| Abstract: | There are different opinions on the existence of microcontinents in Central Asian Orogenic Belt(CAOB) and on the formation age and original rock property of the widely outcropped Xilin Gol Complex.The Xilin Gol complex comprises geologic bodies of different rock types,different metamorphic degrees,various structural styles and different forming ages.We proposed to disintegrate the Xilin Gol Complex and select the supercrustal rocks there among to be named as Xilinhot Group,which are aluminum-rich argillaceo... |
