Many were probably deposited as micritic limestones and were altered to dolostone after burial. Click for an extra close close-up. It is clear that some original structures (animal burrows?) are preserved in this rock.

These carbonates are composed of oolitic, pelitic fossiliferous and micritic limestone units which have been extensively modified by diagenetic alterations, particularly dolomitization. Field observations show two distinct types of dolostone geobodies (i) bedding parallel stratiform, and (ii) patchy dolostone units respectively.MARBLE, LIMESTONE, and DOLOSTONE (See also FOSSILIFEROUS ROCKS TRAVERTINE entries.)

in burrowed/fossiliferous dolostone, and the lowest values of NRM intensity are measured in laminated/bedded dolostones associated with anhydrite. The NRM intensity tends to increase towards the centre of the Williston Basin suggesting that the most probable variables affecting NRM intensities are: 1) depth of sampling and 2) proximity toDolostone (a rock composed of dolomite) is an important reservoir rock. The composition of dolomite is CaMg(CO 3) 2, and it is formed by replacement of calcite and by occlusion of pore space. In the following dolomitization equation, x = the amount of carbonate added to the rock in excess of the amount in the sediment.fossiliferous. The dolostone occurs with dark gray weathering, thin-bedded limestone, graptolitic siltstone that weathers silvery and contains small brachiopods, orange-brown weathering,
