Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat. In its pure form, marble is a white stone with a crystalline and sugary appearance, consisting of calcium carbonate (CaCO 3).Usually, marble contains other minerals, including quartz, graphite, pyrite, and iron oxides.These minerals can give …Calcite is number 3 on the Mohs hardness scale; thus, it can be scratched readily by a knife blade or geologic pick. It has a specific gravity of 2.71. Three perfect cleavages give calcite its six-sided polyhedrons with diamond-shaped faces; the angles defining the faces are 78° and 102°. The three important crystal habits (distinctive shapes ...

Limestones are for the most part primary carbonate rocks. They consist of 50 percent or more calcite and aragonite (both CaCO3). Dolomites are mainly produced by the secondary alteration or replacement of limestones; i.e., the mineral dolomite [CaMg(CO3)2] replaces the calcite and aragonite minerals in limestones during diagenesis.Dolomite. The mineral dolomite is the main component of the sedimentary rock that is also called dolomite. It is similar to the mineral calcite but contains magnesium as well as calcium.

It may contain considerable amounts of magnesium carbonate (dolomite) as well; minor constituents also commonly present include clay, iron carbonate, feldspar, pyrite, and quartz.Based on some experimental data where mineral precipitation temperature and clumped isotope derived temperature doesn't match, a need of mineral specific calibration emerges. The mismatch arises since bonding in magnesite is different from calcite/dolomite and/or acid digestion is conducted at higher temperature.2.1. Preparation of inorganic catalysts from Aceh's local dolomite minerals Initially, the dolomite minerals are crushed with a mortar led to obtain smaller particles by using a mortar led. The particles are then crushed into powder and then sieved using a sieve so that it is expected to obtain particles with an average size of around 75 m.The significance of specific mineral content (e.g., quartz, dolomite, calcite, feldspar, and clay) on the rock strength can be verified by the ANOVA statistical tool. Using the Mixed Stepwise Regression method, the predicted rock strength by mineral composition can achieve the maximum significance by simultaneously considering multi-minerals.
