... of the pyrometamorphic Hatrurim Complex. The Hatrurim Complex, which extends through Israel, Palestine, and Jordan within the Dead Sea Rift zone, mainly comprises larnite, gehlenite, and spurrite rocks. Osbornite, in close association with iron phosphides, barringerite, and schreibersite, occurs at contacts between...

...Yurii V. Seryotkin; Ella V. Sokol; Vladimir V. Bakakin; Anna Y. Likhacheva Abstract A detailed mineralogical study and single-crystal X-ray analysis were carried out on K-Mg osumilite from high temperature pyrometamorphic rocks. These rocks were generated during spontaneous combustion of coal...

...Michael A. Cosca; Eric J. Essene; John W. Geissman; William B. Simmons; Donald A. Coates Abstract Glass-bearing pyrometamorphic melt-rock, formed during natural burning of Tertiary coal in the Powder River Basin, Wyoming, contains a variety of high-temperature igneous minerals, some with diverse...

Galuskina; Yevgeny Vapnik; Evgeny Galuskin Abstract Flörkeite, a rare zeolite with PHI (phillipsite) framework type, was found in numerous amygdaloidal voids in pyrometamorphic rocks of the Hatrurim Basin, Hatrurim Complex, Israel. This is the second...

... been discovered in pyrometamorphic gehlenite-bearing rocks of the Hatrurim Complex, Negev Desert, Israel. The name “silicocarnotite” has been used for the synthetic phase Ca 5 [(SiO 4 )(PO 4 )](PO) 4 for more than 100 years. The holotype specimen is a gehlenite–fluorapatite rock with minor andradite...

Calciolangbeinite- O is found in sublimates of the active Arsenatnaya fumarole at the Tolbachik volcano, Kamchatka, Far Eastern Region, Russia and in pyrometamorphic...

...Leone Melluso; Sandro Conticelli; Massimo D’Antonio; Nicoletta P. Mirco; Emilio Saccani Abstract Two small outcrops of wollastonite- and melilite-bearing paralavas, with a pyrometamorphic genesis, have been found along the Apennine chain, in Central Italy, at the localities of Colle Fabbri...

...), and the meteoritic phosphides florenskyite, FeTiP and andreyivanovite, FeCrP. From the point of view of chemical composition, nickolayite is an Fe-analogue of monipite, MoNiP. The mineral was discovered in the Daba-Siwaqa complex, Central Jordan, a part of the pyrometamorphic Hatrurim Formation (the Mottled Zone...
