Miscellaneous notes

Quarries are numbered and ordered from north to south. In the case of limestone and sandstone, the quarries are grouped according to region and geologic formation. The formation descriptions apply only to areas bordering the Nile River. All quarries are plotted on the accompanying maps. Coordinates for the approximate quarry centers are based on the WGS 84 datum and correspond with locations visible in Google Earth.

Quarry age and size are given in parentheses after the quarry location. Abbreviations for age are: Paleo = Palaeolithic, Neo = Neolithic, Pd = Predynastic, ED = Early Dynastic, OK = Old Kingdom, 1IP = First Intermediate Period, MK = Middle Kingdom, 2IP = Second Intermediate Period, NK = New Kingdom, 3IP = Third Intermediate Period, LP = Late Period, Pt = Ptolemaic, R = Roman, B = Byzantine or Late Roman, and Is = Islamic. Other abbreviations include: OK:4 = Fourth Dynasty of the Old Kingdom, OK/MK = Old Kingdom and/or Middle Kingdom, and NK-R = New Kingdom through Roman Period. Size corresponds to the maximum dimension of an area of quarry workings or the cumulative maximum dimensions for multiple areas of workings within a single quarry. Three size classes are recognized: small (<100 m), medium (100-1000 m), and large (>1000 m).

The standard Udden-Wentworth grain-size scale is used for sandstones: gravel (in conglomeritic sandstone) > 2 mm, very coarse sand 1-2 mm, coarse sand 0.5-1 mm, medium sand 0.25-0.5 mm, fine sand 0.125-0.25 mm, very fine sand 0.0625-0.125 mm, and silt < 0.0625 mm. The predominant grain size for limestones is characterized as: coarse > 1 cm, medium 2 mm-1 cm or fine <2 mm, where the grains (all larger than 0.03 mm) are fossil bioclasts, non-skeletal carbonate grains (e.g., ooliths and peloids) and non-carbonate grains (e.g., quartz silt and sand). Carbonate mud is composed of material finer than 0.03 mm. The popular Dunham (1962) textural classification is applied to the limestones: mudstone (nearly all carbonate mud with rare grains), wackestone (mostly carbonate mud with common grains), packstone (mostly grains with carbonate mud filling the interstices), and grainstone (mostly grains with calcite cement filling the interstices).

_____________________ LIMESTONE _____________________

The ancient names for limestone were inr HD nfr n ain (iner hedj nefer n ain) and inr HD nfr n r-Aw (iner hedj nefer n raw), both translating as “fine (nfr) white (inr HD) stone of Tura-Masara (ain or r-Aw with these terms referring, respectively, to the cave-like quarry openings and the nearby geothermal springs at Helwan)”. In the Old Kingdom these names referred specifically to the Tura-Masara limestones but later they were applied to all such rocks irrespective of source. In these names, the nfr or HD or even both were sometimes omitted.

Mediterranean Coast

Alexandria Formation (Pleistocene): fine-grained, packstone to mainly grainstone with mostly non-skeletal carbonate grains (especially ooliths and coated grains), making it a “oolitic limestone” or a “carbonate sandstone” or “calcarenite” due to abundant sand-sized carbonate grains. Non-clayey, non-dolomitic, and non-siliceous, but occasionally has detrital quartz silt and sand.

Occasionally dolomitic, gypsiferous, and clayey (marly) with common detrital quartz silt and sand. Slightly siliceous with nearly ubiquitous microscopic secondary quartz.

_________ TRAVERTINE ("Egyptian Alabaster") _________

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. The ancient Egyptian name for travertine is Ss [shes] and, in the Old Kingdom, bit [bit]. The Romans called it lapis alabastrites and lapis onyx, and it was the alabastro cotognino [and venato], and alabastro [Egiziano or onice] of the Italian stonecutters. The ancient alabastrites (after the alabastron jars) is the origin of the petrologically incorrect name of "alabaster." Alabaster, as now defined by geologists, refers to a variety of rock gypsum.

General description: alternating bands of opaque white, fine-grained calcite and translucent, yellowish-brown, coarse-grained calcite, and occasionally massive amber-brown calcite [= calc-sinter travertine].

____________________ SANDSTONE

Sandstone was called inr HD nfr n (iner hedj nefer n rewdjet) or occasionally inr HD mnx n rwDt (iner hedj menech n rewdjet), both meaning “fine or excellent (nfr or mnx, respectively), light-colored (inr HD) hard stone (rwDt).” Although usually translated as “white,” here inr HD probably has a more general meaning of “light colored.” Sandstone is not normally considered a hard rock (rwDt), but it is often harder than limestone. In these names, the nfr or HD or even both were sometimes omitted, and the n was later dropped.

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.

All rock formations belong to the Nubia Group and, with the exception of the Duwi Formation, are together informally referred to as the Nubian Sandstone.


Duwi Formation (Upper Cretaceous, Late Campanian to Early Maastrichtian stages): very fine- to medium-grained sandstone with mainly massive to planar bedding and occasional tabular cross-bedding.
