Limestone And Marble Form Project

Sedimentary rocks form layers at the bottoms of oceans and lakes.

Limestone and marble form project.

Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral foraminifera and molluscs its major materials are the minerals calcite and aragonite which are different crystal forms of calcium carbonate caco 3 a closely related rock is dolomite which contains a high percentage of the mineral dolomite camg co 3 2. As the rock is subject to natural heat and pressure it recrystallizes growing harder and denser over time. Marble is a metamorphic rock formed when limestone is exposed to high heat and pressure within the earth. When limestone experiences high heat and pressure beneath the earth it may transform into marble a metamorphic rock.

Under the conditions of metamorphism the calcite in the limestone recrystallizes to form a rock that is a mass of interlocking calcite crystals. Sure klean 1260 limestone marble poultice is an easy to use low odor paste poultice. When the pressure continues it can turn into marble. 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.

It is generally thought to be from italy but in actuality it is quarried all over the world. Share this science project limestone is composed of tiny shells that fell to the ocean s floor when sea creatures died. Layers of sedimentary rocks are called strata. Marble has the same general properties of limestone and can stain etch or scratch but only becomes more beautiful over time and use.

The internal carbonate crystal structure of limestone and marble are different to each other. Marble granular limestone or dolomite i e rock composed of calcium magnesium carbonate that has been recrystallized under the influence of heat pressure and aqueous solutions. Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. Limestone a sedimentary rock forms when shells sand and fossils solidify over millions of years.

Most marble has veining mineral deposits throughout. Commercially it includes all decorative calcium rich rocks that can be polished as well as certain serpentines verd antiques.
