Marble Rock Density

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism.

Marble rock density.

The racial makeup of the city was 99 39 white and 0 61 from two or more races. Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat. The streak of marble is white whereas its fracture is not available. Streak is the color of rock when it is crushed or powdered.

It is composed primarily of the mineral calcite caco 3 and usually contains other minerals such as clay minerals micas quartz pyrite iron oxides and graphite under the conditions of metamorphism the calcite in the limestone recrystallizes to form a rock that is. Some of the heaviest metallic minerals like iridium and platinum can have densities as high as 20. There were 157 housing units at an average density of 187 9 per square mile 72 2 km 2. 1 kg m3 0 001 g cm3 0 0005780 oz in3 0 16036 oz gal imperial 0 1335 oz gal u s 0 0624 lb ft3 0 000036127 lb in3 1 6856 lb yd3 0 010022 lb gal imperial 0 008345 lb gal u s 0 0007525 ton yd3.

Marble is commonly used for sculpture and as a building material. The population density was 390 1 people per square mile 149 8 km 2. 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 marble a pink brown gray green or variegated coloration. The hardness of marble is 3 4 whereas its compressive strength is 115 00 n mm 2.

Rocks with hardness 1 3 are soft rocks from 3 6 are medium hardness rocks and 6 10 are hard rocks. Density of marble solid is equal to 2 711 kg m. Most of the major rock forming minerals in the earth s crust like quartz feldspar and calcite have very similar densities around 2 6 to 3 0 g cm 3.
