Lithostratigraphy and palynostratigraphy of the Lower Gondwana formation in the Hutar Coalfield, Palamau District, Bihar

Abstract

The paper deals with the various aspects of lithostratigraphy of the Hutar Coalfield alongwith the palynoflora recovered from the various formations. The palynozonation of the Lower Gondwana formations has been done on the basis of palynofloras recovered from the samples belonging to three measured sections along Deori Naja, Saphi Nala and Koel River. Extension of these zones in various other nalas of the Hutar Coalfield has been traced. Comparison of these palynozones with those in other Lower Gondwana coalfields has also been done. Assemblage Zone 5 of the Barakar Formation contains a palynoflora similar to the Barren-Measure Formation of other coalfields.
