Dolomite: A sedimentary rock known as dolostone or

Dolomite, also known as "dolostone" and "dolomite rock," is a sedimentary rock composed primarily of the mineral dolomite, CaMg(CO3)2 Dolomite is found in sedimentary basins worldwide It is thought to form by the postdepositional alteration of lime mud and limestone by magnesium-rich groundwater Dolomite and limestone are very similar rocksDolomite Rock - Sedimentary Rocks,Dolomite rock Dolomite or dolostone is a carbonate sedimentary rock containing more than 50% by weight of the mineral dolomite Dolomite rock may contain calcite, but the content of calcite should not exceed 10% of the calcite-dolomite pair’s content 3 Dolomite in Northern Norway (Trollholmsund) which was once chalk,Dolomitic sedimentary rocks - csmgeocsmjmuedu," Pure" dolomite resembles micrite, being a fine-grained carbonate rock with conchoidal fracture, although it can be slightly granular too But dolomite is a secondary rock produced by the chemical alteration of any preexisting carbonate rock, so in fact dolomites can be as diverse as limestone

Sedimentary Rocks | Pictures, Characteristics, Textures, Types

Dolomite (also known as "dolostone" and "dolomite rock") is a chemical sedimentary rock that is very similar to limestone It is thought to form when limestone or lime mud is modified by magnesium-rich ground water The specimen shown above is about four inches (ten centimeters) acrossRock Types - Dolomite,Sedimentary Rocks Mineralogy: Contains a high proportion of dolomite (the mineral and the rock have the same name) Detrital minerals and secondary silica (chert) may be present Field relations: Dolomites are usually interbedded with other limestone s and are commonly associated salt and gypsium depositsSedimentary rock - Limestones and dolomites | Britannica,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 continue to be debated

DOLOMITE (Calcium Magnesium Carbonate)

Dolomite, which is named for the French mineralogist Deodat de Dolomieu, is a common sedimentary rock-forming mineral that can be found in massive beds several hundred feet thick They are found all over the world and are quite common in sedimentary rock sequences These rocks are called appropriately enough dolomite or dolomitic limestoneDolomite Rock | History | Origin,Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight Dolomite is available in black, brown, colourless, green, grey, pink, white colors The streak of a rock is the color of powder produced when it is dragged across an unweathered surfaceLimestone - Sedimentary rocks,Limestones are rocks that are composed of mostly calcium carbonate (minerals calcite or aragonite) Carbonate rocks where the dominant carbonate is dolomite (calcium magnesium carbonate) are named dolomite rock Carbonate rocks together make up one-fifth of all sedimentary rocks

Most of these rocks are limestones and cherts Chemical sedimentary rocks are formed by direct chemical precipitation from water While some limestones and cherts may form in this manner, evaporite deposits consisting of halite, gypsum, and other salts are the most commonDolomite Facts - Softschools,Dolomite is actually a type of limestone Although dolomite can be found in sedimentary and metamorphic rock, it is rarely seen in metamorphic rock Dolomite is used in the manufacturing of bricks that are used to produce steel Dolomite received its named after a French mineralogist named Deodat de DolomieuUniversity of Minnesota’s Mineral Pages: Dolomite,In Our Earth: The Geologic Importance of Dolomite In sedimentary dolostones, dolomite is most often associated with calcite, aragonite, gypsum, anhydrite, chert, and halite Vein deposits of dolomite occur with quartz and other common vein minerals, such as calcite, magnesite, fluorite, siderite, and

The dolomite which does occur in sedimentary rocks is commonly Ca-rich, having compositions which range from about Ca(Ca 016 Mg 084)(CO 3) 2 to ideality, and/or exhibits weak, diffuse, X-ray diffraction, suggesting considerably less structural order than its composition should dictate With respect to ideal dolomite, all such naturally occurring dolomite is metastable, and the capacity exists for reactions toDolomites | Encyclopedia,Formation Dolomite is one of the few sedimentary rocks that undergoes a significant mineralogical change after it is deposited Dolomite rocks are originally deposited as calcite/aragonite-rich limestone, but during a process called diagenesis, the calcite and/or aragonite is transformed into dolomiteSedimentary Rocks | Geology - Lumen Learning,Sedimentary rocks formed by the crystallization of chemical precipitates are called chemical sedimentary rocks As discussed in the “Earth’s Minerals” chapter, dissolved ions in fluids precipitate out of the fluid and settle out, just like the halite in Figure 5
