Limestone vs dolostone
Sep 12, 2022 · The large limestone rock formations, previously called dolomite, should have a new name, dolostone, or magnesian limestone. Calcium carbonate limestone is just limestone. Dolostone. Dolostone is a major sedimentary rock formation in the earth’s crust and joins with other sedimentary formations like shale, sandstone, and limestone. Carbonate samples (including dolostone and dolomitic limestone) from S1 show a negative linear correlation between δ 26 Mg and 1/[Mg] (given the uncertainties of δ 26 Mg, R 2 = 0.82; P = 7.35 × 10 −4) (Fig. 12), suggesting that these specimens can be defined by a binary mixing between the calcite and dolomite components with fixed Mg ...

Hand Specimen. Pale yellow-grey mudstone containing the fossil remains of a small arthropod with a segmented exoskeleton. The rock is banded and shows some surface discolouration due to weathering. Rock fizzes with acid, so contains carbonate. This is a soft, though well consolidated limestone (the surface has been scratched).Limestone. Limey shale overlaid by limestone, in Cumberland Plateau, Tennessee. Limestone is a sedimentary rock composed largely of the mineral calcite (calcium carbonate, CaCO 3 ).
