Abstract
Um Bogma Formation exhibits a significant rock unit of the Paleozoic rocks in southwestern Sinai, Egypt. The Formation is subdivided into Lower, Middle and Upper Members with well-displayed paleokarst profile, The carbonate rocks are texturally classified as crystalline dolostone, Sandy Oo-sparite, Bio-micrite pseudo-sparite, Bio-Oo-sparite, silty Bio-Sparie, and Bio-dolosparite. The clastic rocks are texturally classified as Mudstone/Ferruginated Shale, Quartz arenite, and Quartz wacke. The sediments of Um Bogma Formation were subjected to various diagenetic processes which include isochemical and allochemical processes. The Lower member reflects intertidal to subtidal marine depositional environment. The Middle member starts with the open sea shelf environment then followed by shallow subtidal marine environment. The Upper member shows shallow subtidal to lower intertidal that followed by clastic rocks that reflect the regressive sea within tidal flat.
