On the Palynostratigraphy of Argada `'S' seam in the South Karanpura Coalfield, Bihar

Abstract

The miospore assemblage from the coal of Argada 'S' seam, South Karanpura Coalfield, has been described and compared with similar miofloras of the other coalfields of Indian Lower Gondwanas. This miospore assemblage c1osely resembles the mioflora of the shale associated with Argada 'S' seam described by Lele and Kulkarni (1969). In view of the mioflora from a shale band 70' above the Argada 'S' seam described by Lele and Kulkarni (1969) being similar to the mioflora of the Giridih Coalfield described by Maithy (1965), the type area for the Karharbari Stage, Argada 'S' seam has been considered older than the Karharbari Stage of Giridih Coalfield. However, in view of striking difference between the mioflora of Argada 'S' seam and that of the Talchir Stage, it is suggested that Argada 's' seam should be considered as a part of Karharbari Stage and as compared to the Karharbari Stage in the Giridih Coalfield, it should be recognized as of Lower Karharbari Stage.
