Dolomite, type of limestone, the carbonate fraction of which is dominated by the mineral dolomite, calcium magnesium carbonate CaMgCO32.
Along with calcite and aragonite, dolomite makes up approximately 2 percent of the Earths crust. The bulk of the dolomite constitutes dolostone formations that occur as thick units of great areal extent in many sequences of chiefly marine strata. The rock dolostone is referred to by only the mineral namei.e., dolomiteby many geologists. The Dolomite Alps of northern Italy are a well-known example. Other relatively common occurrences of the mineral dolomite are in dolomite marble and dolomite-rich veins. It also occurs in the rare igneous rock known as dolomite carbonatite.
From the standpoint of its origin, the dolomite of dolostones is one of the most interesting of all the major rock-forming minerals. As discussed below, a large percentage of the dolomite in thick marine dolostone units is thought by many geologists and geochemists to have been formed by replacement of CaCO3 sediment rather than by direct precipitation.
Ferrous iron commonly substitutes for some of the magnesium in dolomite, and a complete series very likely extends between dolomite and ankerite CaFeCO32. Manganese also substitutes for magnesium, but typically only to the extent of a few percent and in most cases only along with iron. Other cations known to substitutealbeit in only relatively minor amountswithin the dolomite structure are barium and lead for calcium and zinc and cobalt for magnesium.
Nearly all the natural elements have been recorded as present in at least trace quantities in dolostones. It is, however, unclear which ones actually occur in the dolomite some of them may occur within other mineral constituents of the analyzed rocks. Indeed, only a few of these elementse.g., strontium, rubidium, boron, and uranium Uare known definitely to occur within the dolomite structure.
The dolomite of most dolostones is granular, with the individual grains ranging in size from microscopic up to a few millimetres across. Most dolomite marbles are coarsely granular with individual grains ranging between 2 and 6 millimetres 0.079 and 0.24 inch in greatest dimension. Vein dolomite grains may be up to several centimetres across. Saddle-shaped groups of dolomite crystals, most of which occur on fracture surfaces, measure from 0.5 to 2 centimetres 0.20 to 0.79 inch across.
Dolomite occurs widely as the major constituent of dolostones and dolomite marbles. As mentioned above, the origin of dolomite-rich rocks in marine sequences remains an unresolved problem of petrogenesis.
Dolomiteactually protodolomiteis known to have formed fairly recently in restricted environments such as on supratidal flats that occur in The Bahamas and Florida Keys. Also, no dolomite has been synthesized in an environment comparable to natural conditions. Thus, the explanation for the formation of dolomite in these marine units remains in question. It is now thought that dolostones may be of various origins. Indeed, several different models have been suggested for dolomite formation, each based on diverse considerations, combined with empirical andor experimental data.
Except for models invoking formation of dolomite by direct precipitation, a process thought by most geologists to apply to only a small percentage of all dolostones, each model is based on the assumption that the dolomite of dolostones has been formed by conversion of CaCO3 sediment or sedimentary rocks to dolostone. Thus, the models have been formulated to account for this conversion, which is known as dolomitization.
