Palynology of the North Karanpura basin, Bihar, India 4. Subsurface Palynology of the bore-hole no. K.5

Abstract

The present paper deals with subsurface Palynology of Barakar Stage and Barren Measures present in the bore-hole no. K.5, located in the Baral-Raniganj-Kevendai area, North Karanpura basin (Sheet no. 73E/1), Bihar, India. 34 dispersed spore pollen genera and 39 species have been recovered from Barakar Stage while Barren Measures have yielded 51 genera and 67 species. The palynological assemblage of both Stages comprises trilete, monolete, monosaccate, bisaccate, polysaccate, polyplicate and colpate spores-pollen. The palynological assemblage of Barren Measures have been subdivided into three palynological zones on the basis of percentage of spores-pollen in the material.
