Paleoenvironment and Paleoecological Significance of Microforaminiferal Linings in the Akli Lignite, Barmer Basin,Rajasthan, India

The palynological assemblage of the Akli Lignite in Barmer District of Rajasthan contains a rich variety of microforaminiferal linings.Three types of microforaminiferal linings belonging to benthic communities occur. Two main occurring morphotypes: trochospiral and singlechambered types are most common in the assemblage. These linings are less abundant than spores, pollen grains and dinoflagellates.The paleoecological and paleoenvironmental significance of these microforaminiferal linings suggesting their deposition in low salinityconditions and at a relatively shallow depths in an embayment of an epicontinental sea of Paleocene-Eocene age in Barmer Basin.
