Zusammenfassung: | Objective The Mugagangri group (MP), named by Wen Shixuan (1979) in the southeast Mugegebori Mountain which is the main peak of Mugagangri, is a flysch formation with deep semi-deep marine sedimentary features in the Bangonghu -Nujiang suture zone (BNSZ). The lithology is mainly composed of sandstones, graywackes, siltstones and silty mudstones with low-grade metamorphism. The previously defined Mugagangri group continues from east to west for nearly 2000 km in BNSZ as a matrix part associated with ophiolitic melange blocks, and is considered to be part of the deep marine sedimentary cover of ophiolites. |
