Bangba Fm
Period:
Carboniferous
Age Interval:
late Carboniferous (Bashkirian-Moscovian?)
Province:
Nepal Tethyan Himalaya
Lithology and Thickness
Interbedded mudrocks and quartzose sandstones with locally intercalated glacial-derived diamictites. Up to 90 m thick.
Lithology Pattern:
Glacial till
Relationships and Distribution
Lower contact
Overlies the Col Noir Shale Fm
Upper contact
Underlies Braga Fm of similar facies
Regional extent
Diamictites characterize the Upper Carboniferous to lowermost Permian section of eastern Manang (Bordet et al., 1975), whereas in S. Tibet glacial deposits – indicating that Gondwana had begun to drift towards higher southern latitudes – occur already in the Lower Carboniferous (Garzanti and Sciunnach, 1997).
