Note: travertine occurs as secondary veins and pods in the limestones of the Mokattam, Samalut, and Minia formations. All quarries are in the Eastern Desert and most are within 25 km of the Nile Valley.
General description: alternating bands of white, fine-grained and brown, coarse-grained calcite, and occasionally massive amber- brown calcite [= calc-sinter travertine].
This rock is the alabastrites (after the alabastron jars) of the Greeks and Romans. This terminology is the origin of the petrologically incorrect name of "alabaster." Alabaster, as now defined by geologists, refers to a variety of gypsum.

____________________ SANDSTONE ____________________
Note: all formations belong to the Nubia Group.
General description (based on quarry samples): brownish, highly porous, subarkosic arenite to quartz arenite sandstone (with the former restricted to the finer grain sizes). This friable rock is loosely cemented with quartz, iron oxides (goethite and minor hematite) and chlorite clay plus minor amounts of kaolinite clay and calcite. The sedimentologic descriptions of the formations which follow are based on more general, published studies of the Nubia Group.
