Marble
Marble is a metamorphic rock consisting of carbonate minerals that recrystallize under the influence of heat, pressure, and aqueous solutions (most commonly calcite (CaCO3) or dolomite (CaMg(CO3)2) and has a crystalline texture of varying thickness. Marble is typically not foliated (layered), although there are exceptions. In geology, the term marble refers to metamorphosed limestone, but its use in stonemasonryMarble that contains impurities such as clay minerals, iron oxides, or bituminous material can be bluish, gray, pink, yellow, or black in color.

From mine to kitchen, here's how raw marble is processed
Step 1: Slicing the raw marble. The first step is to obviously source some marble. Once either mined or delivered to the processing plant, the main production phase can commence. Raw marble blocksMarble originates within the Earth’s crust and is popularly known as calcium carbonate (CaCO3). This is the chemical name of marble, which is produced when limestone goes through immense pressure and heat. Marble gets formed under such pressures because the calcite that is required to form limestone recrystallizes.Where Does Marble Come From? Interesting Mineral Rock Facts

Beginners Guide to Quarry Mining An Underground Miner
Quarrying, or removing gravel, sand, rock, and other minerals from the earth's surface, is a process to obtain materials for various purposes, primarily construction. Quarries have a long history and have been integral to erecting many ancient and modern artistic and engineering feats. Quarry mining operations have evolved a great deal sinceMining and the Environment. Although mining provides people with many needed resources, the environmental costs can be high. Surface mining clears the landscape of trees and soil, and nearby streams and lakes are inundated with sediment. Pollutants from the mined rock, such as heavy metals, enter the sediment and water system.3.7: Mining and Mineral Use Geosciences LibreTexts
