Malhmoodite is a phosphate mineral first discovered at a mine called Union Carbide in Wilson Springs, Arkansas, United States. This mine is 10 km west of Magnet Cove, an alkaline igneous complex, and Union Carbide is in a contact region of alkalic igneous rocks and surrounding sedimentary rocks. The mineral has been approved by the Commission on New Minerals and Mineral Names, IMA, to be named for the late Bertha K. Malhmood, the Administrative Assistant of the Branch of Analytical Laboratories, U.S. Geological Survey.

==Occurrence== Malhmoodite occurs perched on kolbeckite plates and seems to be the last deposited in the cavities it occurs. The mineral is very rare, with the only common place to find it in Wilson Springs. However, a few other specimens have been found in Belgium and England.
