Minerals with a palmierite-type structure. Part I. Mazorite Ba3(PO4)2, a new mineral from the Hatrurim Complex in Israel

Abstract

: The new mineral mazorite, ideally Ba 3 (PO 4 ) 2 , a P-analogue of gurimite Ba 3 (VO 4 ) 2 , was discovered in rankinite paralava hosted by the massive gehlenite-bearing pyrometamorphic rocks of the Hatrurim Complex in Israel. Previously, this mineral was also detected in xenolith samples from the Bellerberg volcano in Germany. Holotype mazorite usually forms colourless plate crystals up to 70-100 μm in length but also occurs in small aggregates in association with other rare Ba-bearing minerals such as zadovite, celsian, hexacelsian, bennesherite, sanbornite, walstromite, fresnoite, gurimite, alforsite
