Dolomite, on the other hand, has a more laid-back kind of luster. It usually has a pearly or matte finish, which is less flashy. If calcite is like a shiny glass window, then dolomite is more like a pearl or a smooth pebble. Its luster is softer and doesn't reflect light as brightly as calcite.
The first is modally dominated by dolomite (CaMg(CO 3) 2), the second by calcite (CaCO 3) and there is a complete gradation between the pure dolomite and limestone "end members" indicated by the rock names, calcitic dolomite, dolomitic limestone, magnesian limestone. As the rocks often also contain variable amounts of …
The Voltaian basin of Ghana is the smaller equivalence of the larger central Taoudeni basin with similar geological analogies (Affaton et al. 1980; Apesigah 2008).The review seeks to highlight and to justify from similar Neoproterozoic sedimentary basins exploration successes and with emphasis on similar geological analogies of the WAC.
1. Introduction. The long-lasting "dolomite problem" arose from the fact that dolomites (dolostones) are fairly rich in Precambrian and Paleozoic sedimentary rocks but very limitedly distributed in Meso-Cenozoic deposits (McKenzie and Vasconcelos, 2009; Gregg et al., 2015).Without catalysts, direct precipitation of dolomite is almost …

Tour du Mont Blanc Overview. Standing at a towering height of 4,807m, Mont Blanc is the highest mountain in the Alps. While it hasn't made the Seven Summits list, it's one of the most technical mountains, and it attracts adventurers and thrill seekers looking to either circumnavigate its wide borders or conquer its summit. One of the most ...
The crystal structure of dolomite is similar to calcite with Mg ions substituting for Ca in every other layer. To accommodate this substitution, due to differences in bond lengths between Ca–CO 3 and Mg–CO 3 (238 pm versus 208 pm, respectively), CO 3 in the Mg layer is uniformly rotated about the threefold axis relative to calcite (Reeder and …

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.

Dolomite, or dolostone, is a carbonate sedimentary rock made mostly from the mineral dolomite, CaMg (CO3)2. It commonly occurs in association with limestone and shares many of the same properties, but reacts only weakly with acid. Dolomite often has a sugary texture and is typically off-white to gray in color.
