Dolomite‐rock textures and secondary porosity development …
Non-planar dolomite cement (saddle dolomite) is the latest generation and is responsible for occlusion of fractures and pore space. Dolomitization is closely associated with the development of secondary porosity; dolomitization pre-and post-dates dissolution and corrosion and no secondary porosity generation is present in the associated limestones.

Textural studies of carbonate minerals over the past three decades revealed that their textures are useful tool for understanding of petrogenesis of carbonatites. Petrographic, cathodoluminescence (CL) and electron-microprobe studies on textures of calcite and dolomite were performed for interpretation of evolution of Eppawala carbonatites in Sri …

Grains of Detrital, Secondary, and Primary Dolomite from Cretaceous
This ––––eliminates a possible secondary origin. A detrital origin is eliminated by the absence of inherited textures and by the distribution patterns, for primary-dolomite grains are restricted to marine sandstones. Within these sandstones, the primary-dolomite grains are most abundant in the basinward portions.

Dolomitic sedimentary rocks
Limestone and dolomite are often found together, or closely associated, but their relationships are not always clear." Pure" dolomite resembles micrite, being a fine-grained carbonate rock with conchoidal fracture, although it can be slightly granular too.But dolomite is a secondary rock produced by the chemical alteration of any preexisting carbonate …

Dolomite (rock)
Dolomite is widespread in its occurrences, though not as common as limestone. It is typically found in association with limestone or evaporite beds and is often interbedded with limestone. There is no consistent trend in its abundance with age, but most dolomite appears to have formed at high stands of sea level. Little dolomite is found in Cenozoic beds (beds less that 65 million years old), which has been a time of generally low sea levels. Times of high sea level also tend to be t…

The secondary dolomite crystals are subhedral and euhedral with varying sizes from 0.01–0.10 to 0.5 mm. Uneven distribution of dolomite crystals of various morphologies and sizes is related to different structures of dolomitized rocks responsible for different permeability for the dolomitizing fluid (Figs. 4f, 4g).

Lime and Calcined Dolomite for Use in Steel Plant – IspatGuru
Both high calcium and dolomitic lime enjoys its most extensive use as a flux in refining of the steel in BOF and EAF. Lime is particularly effective in removing phosphorus, sulphur, and silica, and, to a lesser extent, manganese. Lime also has important uses in secondary refining of steel and in the manufacture of steel products.
