(Photo) Leucite as grey-white material in groundmass (“leucitite”). Elsewhere on specimen: Green prismatic diopside. Brown-black prismatic clinopyroxene. Nepheline as hexagonal prisms. Nepheline with hollow cores have been altered to analcime. Colourless needles of fluorapatite. Grey...
Black magnetite octahedra, some with traces of chlorite on their faces. Some magnetite crystals are completely encased in chlorite. Blocky orthoclase crystals form part of the cavity lining. Brown sheaf or club-shaped siderite, yellow hexagonal...

Red danalite with some crystal faces, frozen in matrix with magnetite and fluorite. Specimen measures 62x46x40mm. Click on the image below for a higher resolution version.
Brown pseudobrookite crystals with tiny yellow transparent enstatite crystals. The larger pseudobrookite crystal has a “bend” in it, clearly an abrupt change of growth direction, not rare but also not common at this locality. The...
