Localities

The type locality is the Halamish wadi, Hatrurim Basin, Tamar Regional Council, Beersheba Subdistrict, Southern District, Israel. Murashkoite is found in pyrometamorphic rocks of the Hatrurim Formation, South Levant. It is a typical accessory phase in the marbles and paralavas in the southern Negev Desert, Israel and on the Transjordan Plateau, Jordan. Murashkoite occurs as grains and aggregates up to 2 mm in size closely associated with barringerite and zuktamrurite. The rock-forming minerals include pyroxenes of the diopside-hedenbergite series and anorthite, with subordinate gehlenite, tridymite, cristobalite, pyrrhotite, fluorapatite, chromite, magnetite, hematite, merrillite and late hydrothermal carbonates, silicates and sulphates. Macroscopically, murashkoite is yellowish-grey in colour and has a metallic lustre (Mineralogy and Petrology, 113.2.237-248).
Other associated minerals include transjordanite and halamishite (HOM).
