| Description: | A grey and buff dolomite of varying grain. Dolomitized relics of crinoids, polyzoa and shells are indicated by concentration of mineral dust and granules of pyrite. In the grey part of the rock ferruginous films are abundant. The buff part is coarser in grain and there are pellicles of brown limonite on the grains of dolomite; these have refractive index omega about 1.690 indicative of a moderate content of iron carbonate. Aggregates of chalcedony occur sparsely within the crinoid pseudomorphs. Ferriferous dolomite, zoophasmic, uneven mosaic, taxichnic. SL0064. Britrocks S34553. Magnification x40. Light XPL. |
