"Assyrian kings ruled the world's largest empire prior to the rise of Persia in the 6th century bc, consolidating lands from Iran to Egypt [...] Masterfully executed with incised details and exaggerated musculature, this giant, fierce, protective spirit raises his right hand in a ritual salute. His left hand grasps a branch bearing rosettes, perhaps a stylized date palm. Across the center of the relief are inscribed lines of Akkadian cuneiform recounting military victories, conquests, plundered loot, and the reconstruction of the city. Destroyed in 612 bc, the palace lay buried for 24 centuries until rediscovered in 1845."

Gypsum, gray

Gypsum that was deposited during the Messinian salinity crisis. In the center of the outcrop a well-developed nucleation cone is visible, made of individual selenite gypsum cristals up to 30 cm long which radiate upwards and outwards. Cuevas de Sorbas (a few meters from the cave entrance), Andalusia, Spain. Lat 37˚05‘19.42’‘N, Lon 2˚06‘27.68’‘W, elevation 340 m.

This is a higher-resolution model, showing more details, of the [same outcrop here](https://skfb.ly/6V9ZT). A set of complete gypsum cycles is shown in the [Rio Aguas outcrop model](https://skfb.ly/o9vIu).

Gypsum, pink

Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum is very similar to Anhydrite. The chemical difference is that gypsum contains two waters and anhydrite is without water. Gypsum is the most common sulfate mineral.

Gypsum uses include: manufacture of wallboard, cement, plaster of Paris, soil conditioning, a hardening retarder in portland cement. Varieties of gypsum known as "satin spar" and "alabaster" are used for a variety of ornamental purposes; however, their low hardness limits their durability.
