    “色尔腾山群”的解体及其原岩特征

    Disintegration of Seertengshan Group and characteristics of the protolith

    • 摘要: 野外地质调查和综合研究表明,色尔腾山地区出露的"色尔腾山群"由片状无序变质岩带和变形变质侵入岩区组成,因而认为"色尔腾山群"主体并不具有层序地层特征,应将其解体为色尔腾山岩群和点力素太组及变质斜长花岗岩。文中阐述了色尔腾山岩群地质特征并根据地质特征及同位素测年结果将其划定为新太古代。

       

      Abstract: According to results of survey and research, authors have fond that there is not succession of strate in the named as "Seertengshan Group". It consists mainly of sheet-disorder metamorphism rock belts and deformed metamorphism intrusive rock provinces. The contact of primary with contacted geologic bodies has not been discovered. Thus, authors provide that "Seertengshan group" has not feature of stratigraphic succession. So we consider correcting "Seertengshan" as Seertengsha Group-complex. Authors provide the Seerteng sha Group-complex to belong to Upper Archean on the basis of geologic characteristics and isotopic age.
