Murashkoite is a relatively new mineral, approved in 2012.
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).
