Abstract
The mineralogical and geochemical constituents of the Aptian-Albian Malha Formation at the Abu Darag region, Gulf of Suez, Egypt, can be discussed here. These constituents are related to paleoweathering and paleoclimatic circumstances that managed the depositional settings. The present study aims to evaluate the geochemical conditions that have control over the depositional environments and characterizes them in terms of lithological, mineralogical, and chemical composition. To achieve this aim, selected kaolinitic clay samples were geochemically and mineralogically examined. Kaolinite and quartz are the main constituent minerals in the investigated samples, whereas anatase and hematite serve as auxiliary minerals. The presence of hematite minerals indicates precipitation in an oxidizing environment, whereas anatase is related to basaltic rock. Bivariate discrimination provenance diagrams, major oxides, and trace elements all identify felsic-intermediate igneous source rocks as the leading contenders. The examined samples were deposited in non-marine environments and underwent weak to moderate chemical weathering as well as severe physical induration in tropical climates.
