Miscellaneous notes

Mines are numbered and ordered from north to south. All mines are plotted on the accompanying maps. Coordinates for the approximate mine centers are based on the WGS 84 datum and correspond with locations visible in Google Earth.

Mine age and size are given in parentheses after the mine 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 mine workings or the cumulative maximum dimensions for multiple areas of workings within a single mine. Three size classes are recognized: small (<100 m), medium (100-1000 m), and large (>1000 m).

Amazonite (also amazonstone and green feldspar): translucent to opaque; light to medium green to mainly bluish-green; microcline feldspar [KAlSi3O8]. Ancient names: nSmt [neshmet], also possibly also Hsg [heseg] (Egyptian); probably smaragdos and possibly also iaspis (Greek); smaragdus and possibly its sub-variety galactites (Roman).

Amethyst: transparent; light to dark violet or purple; macrocrystalline quartz [SiO2]. Ancient names: Hsmn [hesmen] (Egyptian); amethystos/amethystus (Greek/Roman).

Carnelian and other chalcedonies: translucent; mainly fibrous/chalcedonic microcrystalline quartz [SiO2] = chalcedony. Three color varieties at Stela Ridge:

(1) carnelian or cornelian -- medium to dark orangy red, brownish-red or red (note that during the Roman period, but possibly earlier as well, carnelian color was often enhanced by heat treatment) plus sard -- medium to dark orangy brown, reddish- to yellowish-brown or brown, and gradational with carnelian. Ancient names: Hrst [herset], and also occasionally Hrst dSr [herset deser] and Drtt [djertet] (Egyptian); sardion (Greek); sarda (Roman).

(2) common chalcedony -- white or pale gray to mainly bluish white/gray. Ancient names: probably Hrst HD [herset hedj] (Egyptian); Greek unknown; probably leuachates and also possibly cerachates and ceraunia (Roman).

(3) green chalcedony -- light to medium green. Ancient names: possibly prDn [predjen] (Egyptian); probably prasinos or prasitis (Greek); prasius (Roman).

Emerald (or green beryl): mainly light to medium green and translucent; rarely dark green and transparent; beryl [Be3Al2(Si6O18)]. Ancient names: smaragdos/smaragdus (Greek/Roman).

Fluorite or fluorspar: transparent to translucent; commonly light or bluish green or yellow, but other or multiple colors are possible [CaF2]). Ancient names: probably murrina or myrrhina (Roman).

Peridot: transparent to translucent; light to medium yellowish-green; olivine [(Mg,Fe)2SiO4]. Ancient names: topazos/topazus and occasionally topazion and bazion (Greek/Roman).

Turquoise: opaque; light to medium green to greenish-blue or light blue with the blue color degrading over time to green; turquoise [CuAl6(PO4)4(OH)8▪5H2O]). Ancient names: mfkAt [mefkat] (Egyptian); probably smaragdos (Greek); callaina (Roman).
