Plagioclase minerals are hard, non-metallic minerals that exhibit two cleavage directions that meet at nearly right angles. The name ‘plagioclase’ refers to this cleavage pattern, coming from the Greek words for ‘oblique’ (plagios) and ‘to break’ (klasis).Apart from pegmatites, the plagioclase minerals seldom occur as well-defined isolated crystals, but …

Dolomite ( / ˈdɒl.əˌmaɪt, ˈdoʊ.lə -/) is an anhydrous carbonate mineral composed of calcium magnesium carbonate, ideally CaMg (CO3)2. The term is also used for a sedimentary carbonate rock composed mostly of the mineral dolomite (see Dolomite (rock) ). An alternative name sometimes used for the dolomitic rock type is dolostone. History 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. Both minerals exhibit the same well-developed rhombohedral cleavage and have roughly the same hardness.Browse 8,311 authentic dolomite mineral stock photos, high-res images, and pictures, or explore additional calcium carbonate mineral or dolomite stone stock images to find the right photo at the right size and resolution for your project. calcium carbonate mineral. dolomite stone. garnet. limestone.

Dolomite. Dolomite is a calcium magnesium carbonate mineral which has many characteristics similar to calcite. In places where access to limestone is not available or more costly, dolomites are used in its place for the basic materials from which most building stone and a significant percentage of crushed stone are produced.

It is also called dolostone, due to the confusion that can be made with the mineral dolomite, which is a significant part of the stone’s composition.

Crystallized dolomite is found as an accessory mineral in many ore deposits, and as a common mineral in some hydrothermal deposits as discrete crystals, and excellent collector specimens. Dolomite, as noted, is a calcium magnesium carbonate so it is relatively soft, just a bit harder than calcite.

Limestone is an occurring type of sedimentary carbonate rock found on Earth’s surface. It is formed when crystals of calcium carbonate precipitate out of water containing dissolved calcium. Limestone is composed of minerals such as calcite and aragonite. Limestone consists of 80 percent calcite and Dolomite with more than 50% calcium carbonate.
