The rocks exposed in the study area are carbonates of Lockhart Limestone. The carbonates are nodular, thin to thick bedded, fossiliferous with minor intercalcations of marl. The microfacies investigation was carried out in two different geological field sections based on field and petrographic data in the area. The carbonate microfacies are, Micritic Crystalline Carbonate Mudstone-Wackstone Micrifacie (LMF-1), Mixed Bioclastic Mudstone-Packstone Microfacies (LMF-2) and Benthic Foraminiferal wacke-Packstonet Microfacies (LMF-3). The recognized fossils are Algaes, Texularia, Tokhartia sp, Opperculina, Assilina sp, Nimmulites sp, Ranikothalia sp, Mascellena sp, Nodosaria and Milliolid. The deposition of limestone with larger benthic foraminifer took place. The large Foraminifera’s and dasycladacean algae in the rocks indicate shallow marine shelf environment. The carbonate microfacies suggested limestone deposition under clastic free shallow shelf conditions. The predominantly wackstone to packstone fabric nodularity in limestone and presence of fossils suggest deposition in shallow marine environment.
