Three types of dolomite have been identified: fine to mediumcrystalline floating dolomite (D1), fine to coarsecrystalline matrix dolomite (D2), and fine to mediumcrystalline dolomite cements (D3). The three types of light graydark gray limestone mentioned above have thick, massive structure on the outcrop.

Dolomitization process and its implications for porosity development in dolostones: A case study from the Lower Triassic Feixianguan Formation, Jiannan area, Eastern Sichuan Basin, China.
In dolomitic facies, the porosity is ranging from 5% to 14%. In most of the dolomitic samples, the porosity is round about 5%. From the structural analysis and the study of other carbonate...

dolomitization model was developed. The comparative analysis of porosity has been done to find out the impact of dolomitization on the porosity by comparing it to limestone facies. For the porosity analysis, the computerised software Image J (IJ) was used. The methodology was inspired from Grove et al., (2011),

dolomitization 1. n. [Geology] The geochemical process in supratidal sabkha areas where magnesium [Mg] ions from the evaporation of seawater replace calcium [Ca] ions in calcite, forming the mineral dolomite.
The process in which dolomite is produced from limestone is called dolomitization. The Characteristics of Dolomite Although the mineral dolomite was first identified in the mountains of northern...
Dolomitization. One of the "legacy" slide/audiotape programs from the mid1980s—now available on DVD! Lynton Land presents and describes the various models for dolomitization, and examples are offered. The mineralogy, geochemistry, and petrology of dolomite is introduced and summarized as pertaining to the timing and mechanisms of ...
Dolomitization is a geological process by which the carbonate mineral dolomite is formed when magnesium ions replace calcium ions in another carbonate mineral, calcite. It is common for this mineral alteration into dolomite to take place due to evaporation of water in the sabkha area. [1]

Dolomitization can overwrite primary poresystem development, and control flow and storage capability of affected rocks (Lucia Major, 1994). Owing to the nearsurface nature of the marine diagenetic environment in which such dolomitization is understood to occur, exposure of these early dolomites to meteoric waters following a relative sea ...
Dolomite porosity ranges from 25% to 5%, suggesting a porefilling phase. The dolomite beds are concentrated at the top of the outcrops, with the lowest porosity values at the top and the highest porosity downdip near the change to limestone.
Dolomite can occur via two possible mechanisms, direct precipitation and through the dolomitization process, in which calcite dissolves, supplying Ca 2+ ions, followed by the precipitation of...
a close look at the "dorag" mixingzone model (badiozamani 1973) reveals several serious weaknesses: 1) the range of freshwaterseawater mixtures that meet the dorag requirement for dolomitization shrinks to a small "window" if the geologically more realistic disordered dolomite is used in the calculations instead of the ordered dolomite on which .
The process of converting calcium carbonate to calciummagnesium carbonate is known as dolomitization. When compared with limestone, dolomite is harder and less likely to react with acids. It is ...
سورة الحجر كغيرها من سور القرآن هي ذات فوائد متعددة، وتأثير إيجابي على حياة الأشخاص، فجميع سور القرآن ذات تأثيرات إيجابية للقارئ، وسورة الحجر لها عدد من الفضائل أهمها ما يلي: معرفة أن هناك العاصين المكذبين، الذين يعاندون أوامر الله تعالى ونواهيه. وأن هؤلاء موجودون في كل وقت وحين، وأن من سلك طريق الدعوة عليه ألا ييأس، أو يتكاسل عما كلف به.
Dolomitization is the geological process in which Magnesium ions replace Calcium ions in a mineral called calcite to form carbonate mineral dolomite. It depends on specific conditions which include low Ca: Mg ratio in solution, reactant surface area, the mineralogy of the reactant, and high temperatures. Hence the dolomite mining companies are ...

The process of dolomitization, by which limestone is replaced by dolomite, has been studied for centuries, but there is still no cohesive understanding of how this occurs. It is particularly enigmatic because modern oceans are enriched in Mg, but dolomite does not precipitate directly from seawater in the same way that calcite does.
Dolomitization is a geological process by which the carbonate mineral dolomite is formed when magnesium ions replace calcium ions in another carbonate mineral, calcite. It is common for this mineral alteration into dolomite to take place due to evaporation of water in the sabkhas area.
As an opposite process of dolomitization, the studies of formation condition of dedolomitization and calcitedolomitesolution system can help to analyze the origin of dolomitization. The nearsurface dedolomitization is generally relevant to the dissolution of gypsum and the meteoric water of vadose zone and phreatic zone.
Dolomitization model and formation depend on the source dolomitization site and lastly, there must exist a favorable condition for a chemical reaction. One particular type of dolomite which may be ...
Dolomitization is an ubiquitous phenomenon of metasomatism in the diagenetic realm (Machel, 2004;Warren, 2000), where a carbonate rocks (CaCO3) interacts with a magnesiumrich fluids to form...
