Calcit Dolomite Aragonite Manufacturing

Calcite and Dolomite University of Pittsburgh

Calcite and dolomite are very similar minerals. Both have the same hardness (H = 3), the same rhombohedral cleavage, and are found in identical geologic settings. The best way to tell one from the other is the acid test: a drop of 1 M HCl on calcite produces an instant, obvious fizz a drop on

Sedimentary rock Limestones and dolomites Britannica

Sedimentary rock Sedimentary rock Limestones and dolomites: Limestones and dolomites are collectively referred to as carbonates because they consist predominantly of the carbonate minerals calcite (CaCO3) and dolomite (CaMg[CO3]2). Almost all dolomites are believed to be produced by recrystallization of preexisting limestones, although the exact details of this dolomitization process

Dolomite Mineral and Healing Properties

Well there are no good simple answers, but it appears that dolomite rock is one of the few sedimentary rocks that undergoes a significant mineralogical change after it is deposited. They are originally deposited as calcite/aragonite rich limestones, but during a process call diagenesis the calcite and/or aragonite is altered to dolomite.

Calcite an overview ScienceDirect Topics

Calcite, crystallizing in the rhombohedral crystal system is the thermodynamically stable phase of calcium carbonate. Aragonite, calcite''s orthorhombic polymorph, is about 1.5 times more soluble than calcite. Magnesian calcite is an important subgroup of carbonates that occurs as skeletal components and marine cements.

Mystery solved: Why seashells'' mineral forms differently

Mar 02, 2015 · For almost a century, scientists have been puzzled by a process that is crucial to much of the life in Earth''s oceans: Why does calcium carbonate, the tough material of seashells and corals, sometimes take the form of calcite, and at other times form a chemically identical form of the mineral, called aragonite, that is more soluble — and therefore more vulnerable to ocean acidifiion?

So in general a sample that reacts vigorously with acid is more likely to be calcite, rather than aragonite. Dolomite: Dolomite is a mineral that most often forms as an alteration of calcite, as magnesium replaces much of the calcium in the crystal structure. Consequently, it is not unusual for the two minerals to occur together.
