Late Barakar flora from the Chaturdhara Nala section, Ib-River Coalfield, Sundargarh, Orissa, India

Abstract

The Chaturdhara Nala section is located on the north-western side of Gopalpur Village, Sundargarh District, Orissa. The surface palynological investigation found the samples collected from the Chaturdhara Nala section near the junction of Basundhara Nala section. In the present occurrence Faunipollenites and Striatopodocarpites prominance and followed by Rhizomaspora, Scheuringipollenites, Distriatites,Cyclogranisporites, Cyclobaulisporites, Densipollenites, Striatites and Alisporites etc. On the basis of palynoassemblage it is suggested that these sediments were deposited in the Late Barakar age. A similar palynoassemblage is found in the earlier study of bore-hole number IBH-6 from this area. The dominance of striated disaccate taxa followed by non-striated disaccate spores in the present study hence, the present palynoassemblage is equal to the Late Barakar age of other basins, India.
