(A) Superposition of palisade crusts (pc) in the basal part of the Kakeled Limestone Bed at Bruddesta with arrowed polymetallic veins. (B) Slab of a glendonite rosette embedded in the black shale interbeds separating the Exporrecta Conglomerate and Kakeled Limestone beds at Degerhamn. (C) Cathodoluminescence thin-section photomicrograph showing the core of a glendonitic aggregate, with zoned dull-orange luminescence, displaying the prismatic chevron-like habit of stellate pseudomorphs. (D) CL photomicrograph of a lag accumulation showing a mixture of non-luminescent (polymetallic sulphides) and dull-brownish luminescent glendonitic clasts embedded in a brightly yellowish cement.
