Name:
Named after Wadi Gorer in the Negev Desert, Israel. This wadi is situated in close proximity to the Hatrurim Junction along the road connecting Arad City with the Dead Sea, near the type locality of gorerite.
An example of calcium ferrite aluminate. The AlFe (or, more specifically, AlFe11) analogue of hibonite. Also related to barioferrite by the CaAlFe11-for-BaFe12 substitution.
Chemically close to brownmillerite-srebrodolskite series.
Chemically close to brownmillerite-srebrodolskite series.

Type Occurrence of Gorerite
General Appearance of Type Material:
intergrowths of platy crystals of gorerite up to 50 µm in size.
Place of Conservation of Type Material:
collections of the Fersman Mineralogical Museum, Russian Academy of Sciences, Leninskiy Prospekt 18-2, Moscow 119071, Russia, registration number 5420/1
Geological Setting of Type Material:
it emerged through a reaction involving earlier crystallized hibonite and an iron-enriched melt, resulting in the partial or complete replacement of hibonite by gorerite in a It was found in ferrite-rich segregations of esseneite-gehlenite-wollastonite-anorthite melted rock of the ‘olive’ subunit of pyrometamorphic rock.
