The investigated dolomitic marble shows no remarkable foliation and commonly shows granoblastic texture. It consists mainly of Mg-rich calcite, dolomite, and olivine (Fo ~89–93), with a small amount of tremolite, clinohumite, and phlogopite along with trace apatite (Fig. 2a). Carbonate minerals (calcite and dolomite) occur in a wide range …
Dololime is crafted from premium dolomitic limestone sourced from high-quality deposits. Our limestone boasts a magnesium carbonate content ranging from 40% to 44%, ensuring superior quality and purity.
Dolomite is a limestone compound containing calcium and magnesium.. The best mixtures contain 8 to 12 percent magnesium and 18 to 23 percent calcium. These elements influence the soil pH while providing valuable nutrients to your plants.
ECHNICAL DATAPCC 200 AGRICULTURAL DOLOMITIC LIMESTONE. PCC Agricultural Dolomitic limestone is manufactured from a dolomitic (Calcium Carbonate – Magnesium Carbonate) quarry at our Catanach plant in Malvern, Pennsylvania. It is a finely particled, tan product and is used in a variety of agricultural applications.

The "dolomite problem", which has confused scientists for nearly two centuries, is an important fundamental geological problem. The mineralogical characteristics of carbonate minerals show that the dolomite structure consists of an ordered arrangement of alternating layers of Ca 2+ and Mg 2+ cations interspersed with C O 3 2 − anion …

There are three distinct types of limestone, defined by their magnesium carbonate (MgCO 3) concentrations.These types are Dolomitic (35 to 46% MgCO 3), Magnesian (5 to 35% MgCO 3) and High calcium (less than 5% MgCO 3).
The highly dolomitized Main Limestones of approximately Mississippian age, which crop out in South Wales, are classified according to their Ca Mg ratio values. The results based upon the Ca Mg ratio determination of these rocks permitted their classification into six major categories, namely: (1) limestone; (2) slightly dolomitized …
Due to the continued Mg 2+ loss during advanced stage of the dolomitization process, the dolomitizing fluid will approach the dolomite–calcite–water three-phase equilibrium and pass a kinetic threshold below which dolomite precipitation is significantly limited while dissolution rates of calcite remain relatively rapid (Machel, 2004 ...
