Aggregate resources of the Abha-Khamis Mushayt area: A preliminary report, Kingdom of Saudi Arabia

The area within 30 km of Abha and Khamis Mushayt in the Asir province of the Kingdom of Saudi Arabia is experiencing rapid growth and a corresponding strong demand for construction materials, including aggregate. The major source of aggregate at present is wadi gravels, supplemented by shallow pits in bedrock. A vast quantity of coarse aggregate as yet untouched is readily available near Abha and Khamis Mushayt in the granite, gabbro, and gneiss bedrock that underlie the area. Fine aggregate of high quality is readily available in the major wadis.

Asbestos occurrences in serpentinites of the Hamdah area, Kingdom of Saudi Arabia

A cluster of serpentinite bodies centered at 19°00'N. and 43°45'E., near the village of Hamdah, contain many occurrences of the fibrous asbestos minerals chrysotile and anthophyllite. In the south-central part of the area, near the ancient Hajr gold mine (18°54'45"N. and 43°40'30"E.), the fiber is of fair quality and grade but the estimated quantity is too small to be of commercial interest. Elsewhere in the Hamdah area the serpentinite contains some small concentrations of anthophyllite but only traces of chrysotile.
