Biostratigraphy, microfacies analysis and depositional environment of the Bartonian–Priabonian limestones in Shan-Abad anticline (west of Rafsanjan) [PDF]
Journal of Stratigraphy and Sedimentology Researches, 2021 The Middle–Late Eocene carbonate deposits have developed in the Shan-Abad anticline as a thin belt among volcanic rocks. The nummulite banks are one of the most interesting deposits in this belt and composed of nummulite accumulations in the form of ...

Eocene foraminiferal biofacies in Kutch Basin (India) in context of palaeoclimate and palaeoecology
Journal of Palaeogeography, 2019 The Eocene Epoch passed through multiple hyperthermal events and recorded highest temperatures in the Cenozoic. Very few studies from Eocene palaeotropical sites have recorded changes in shallow marine foraminiferal assemblages.
