Description: | A grey crystalline dolomite with crinoid ossicles. Consisting of grains and rhombs of ankeritic dolomite of 0.05 - 0.3 mm grain-size. The refractive index, omega = 1.695, indicates about 20 per cent of the ferrodolomitic component. Large grains of carbonate representing crinoid ossicles have shapeless boundaries owing to irregular replacement by smaller rhombs of dolomite but are nevertheless themselves converted to dolomite. Opaque pellicles, in part at least of pyrite, are frequent on the surface of the recrystallized carbonate grains. Ferriferous dolomite, medium-grained, zoophasmic, uneven mosaic. SL0037. Britrocks S34458. Magnification x40. Light XPL. |
