| Description: | A grey cavernous limestone of fine grain, the cavities in some cases represent shells dissolved away; small black pellets are numerous in patches. Composed of a large number of large fairly thin-walled shells, which enclose turbid calcite-mudstdne in various stages of recrystallization, in a partially recrystallized and dolomitized matrix. The less recrystallized portions show a clotted structure, contain fragments of thin shells and in places contain rolled or angular fragments of shelly calcite-mudstone, shell fragments coated with precipitated calcite and, more rarely, ooliths, together with fragments of hollow structures, perhaps spines. Refractive index tests show that both dolomite and ankerite are present. Limestone, dolomitic, pelitomorphic, fossiliferous, clotted, pseudo-oolitic. Britrocks S35065. Magnification x40. Light XPL. |
