| 摘 要： | 通过对华北(内蒙古白云鄂博—上海市)地学断面内蒙古区带古板块构造的研究,发现华北板块北缘(西段),内蒙古白云鄂博北侧,存在着嘎顺(格少图庙)移置地体。从区域地质及地球物理等方面进行综合分析,认为它来自异地。与其周缘的构造单元没有任何生成联系,其地质发展史亦不相同。本文讨论了该地体的拼贴时间和方式及其大地构造意义。

| Abstract: | Based on an investigation into the paleoplate tectonics of the inner Mon-golian regional transect (from Bayan Obo of Inner Mongolia to Shanghai), itis found that there exists the Gaxun (Geshaotu Temple)allochthonous terraneon the western section of northern margin of the North China plate and alsoon the northern side of Bayan Obo. An integrated regional geological and geo-physical analysis indicates that it came from some other place and has nogenetic connection with its neighboring tectonic units, as is also shown by thedifference in their geologic history. This paper deals with the time and theway this terrane was stuck on other tectonlic units and its geotectonic signi-ficance. |
