Paleo bathymetery and Paleo environment of Fort-Munro Formation at Bara Nala Section, District Jamshoro, Sindh

Abstract

The paleobathymetry and paleoenvironmental analyses were carried out from Fort-Munro Formation (early Maastrichtian age) at Bara Nala Section of Lower Indus Basin. Fort-Munro Formation was succeeded by the Pab Sandstone at all across the Bara Nala Section. Following certain paleontological procedures, a diversified assemblage of age diagnostic benthic foraminifers were observed from the studied section. The variations in grain size revealed the evaluation of transgression-regression curve and relative sea level changes during the deposition of Fort-Munro Formation. Based upon paleontological investigations, marine environmental conditions were inferred possessing inner shelf to bathyal platform.
