dc.description.abstract | Ariegilatite, BaCa12(SiO4)4(PO4)2F2O (R3m, a = 7.1551(6) Å, c = 41.303(3) Å, V = 1831.2(3) Å3,
Z = 3), is a new member of the nabimusaite group exhibiting a modular intercalated antiperovskite
structure derived from hatrurite. It was found in a few outcrops of pyrometamorphic
rocks of the Hatrurim Complex located in the territories of Israel, Palestine and Jordan.
The holotype specimen is an altered spurrite marble from the Negev Desert near Arad
city, Israel. Ariegilatite is associated with spurrite, calcite, brownmillerite, shulamitite,
CO3-bearing fluorapatite, fluormayenite-fluorkyuygenite and a potentially new mineral,
Ba2Ca18(SiO4)6(PO4)3(CO3)F3O. Ariegilatite is overgrown and partially replaced by stracherite,
BaCa6(SiO4)2[(PO4)(CO3)]F. The mineral forms flat disc-shaped crystals up to 0.5 mm in size. It is
colorless, transparent, with white steaks and vitreous luster. Optically, ariegilatite is uniaxial,
negative: ! = 1.650(2), " = 1.647(2) ( = 589 nm). The mean composition of the holotype ariegilatite,
(Ba0.98K0.01Na0.01)S1(Ca11.77Na0.08Fe2+
0.06Mn2+
0.05Mg0.04)S12(Si3.95Al0.03Ti0.02)S4(P1.70C0.16Si0.10S6+
0.03
V0.01)S2F2.04O0.96, is close to the end-member formula. The structure of ariegilatite is described as a
stacking of the two modules {F2OCa12(SiO4)4}4+ and {Ba(PO4)2}4 along (001). Ariegilatite, as well as
associated stracherite, are high-temperature alteration products of minerals of an early clinker-like
association. These alterations took place under the influence of pyrometamorphism by-products,
such as gases and fluids generated by closely-spaced combustion foci. | pl_PL |
