Our forthcoming database will list the porosities of the tested samples, and Figure 1 shows the range and distribution of porosities by lithology. The dolomites have the lowest porosities (2–6%), the shales have the widest range of porosities (8–29%, although most are less than 15%), and the sandstones have the highest porosity (11–32%).A white nonmetallic, natural mineral identified chemically as calcium metasilicate, CaSiO 3.

Dolomite is a calcium/magnesium carbonate mineral. It has a formula unit composition of CaMg(CO 3) 2. Dolomite has a trigonal crystal system with rhombohedral habit. In ideal dolomite, calcium and magnesium are separated into completed separate planes, quite unlike magnesian calcites in which Mg randomly substitutes for Ca. Most dolomite …The formula of calamine ore is : Define a chemical formula. What is the chemical formula of sulphuric acid and Sodium hydroxide? Q. (a) Which metal is extracted from calamine ore?
