It forms white, tan, gray, or pink crystals. Dolomite is a double carbonate, having an alternating structural arrangement of calcium and magnesium ions. Unless it is in fine powder form, it does not rapidly dissolve or effervesce (fizz) in cold dilute hydrochloric acid as calcite does. [9] Crystal twinning is common.
Dolomite (also known as dolomite rock, dolostone or dolomitic rock) is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO 3) 2. It occurs widely, often in association with limestone and evaporites , though it is less abundant than limestone and rare in Cenozoic rock beds (beds less than about 66 ...
The discovery of dolomite rock, or dolostone, was first published in 1791 [8] and has been found across the Earth's crust from various different time periods. [9] Because the rock is made of calcium , magnesium , and carbonate ions, the mineral crystalline structure can be visualized similar to calcite and magnesite . [ 10 ]
In mayo’s case, the incompatible liquids (oil and acid) are slowly added to, and emulsified by, the egg yolks. This emulsion, when done properly, creates the classic condiment for egg salad ...

Acidic rock or acid rock refers to the chemical composition of igneous rocks that has 63% wt% SiO 2 content. [1] Rocks described as acidic usually contain more than 20% of free quartz. [2] Typical acidic rocks are granite or rhyolite. The term is used in chemical classification of igneous rock based on the content of silica (SiO 2).
Authorities in Boston have charged a woman with murder in connection with the death of an attorney found on a houseboat in a marina over the weekend.
Pure white marble is the result of metamorphism of a very pure (silicate-poor) limestone or dolomite protolith. The characteristic swirls and veins of many colored marble varieties, sometimes called striations , are usually due to various mineral impurities such as clay , silt , sand , iron oxides , or chert which were originally present as ...
