A sporological study of seam VII (Jote Dhemo colliery) in the Raniganj coalfield Bihar, India

Abstract

The present paper deals with the sporological study, both qualitative as well as quantitative, of seam VII (Bonbahal seam) of the Raniganj coalfield, Bihar (India). The fossil spore and pollen flora of the seam consists of 40 genera and 85 species, out of which 13 species are new. The miospore assemblage of the present seam (No. VII) has also been compared with that of seam VIII (Jambad Bowlah seam) overlying it, bringing out the significant differences between them.
