Petrological Study of Clay deposits of the Lower Cretaceous in Northern of South Palmyra Folding Zone-Syria

The Petrological study of Clay deposits belonging to the lower Cretaceous in the northern part of South Palmyra Folding Zone. Showed they were formed as a result of weathering processes of igneous rocks within Sedimentary continental climate is hot and wet conditions, and formed lateritic iron soil, followed by enrich, erosion and washing caused by watery agitate and re-replaced for short distances within valleys or grooves or local karst cavities, and later filled by crust erosion materials through the Cretaceous Sea transgression.
