What Are the Characteristics of Limestone?
Like other sedimentary rocks limestone forms from layers of other material that undergoes compression over time. Because of its calcium carbonate limestone is an organic sedimentary rock and much of the calcium in limestone comes from the remains of ancient marine life such as coral.

Magnetism in Rocks
The magnetic field has not always been in its present configuration. At times in the past the poles have reversed or changed direction so that the north magnetic pole becomes south and vice versa. There does not appear to be any regularity to these magnetic reversals as they are called nor do we know how reversals occur.
4 Common Limestone Problems and How to Avoid Them
4 Limestone Problems that You Might Come Across and How to Avoid Them. Weathering: Limestone is a rock which is more prone to especially chemical weathering than other types of rocks such as granite. This is because calcium carbonate which is one of the minerals found in limestone readily reacts with rainwater.

The magnetic properties of most rocks depend on the proportion of magnetite within the rocks. See the approximate percent of magnetite by volume highlighted by the red lines. Igneous rocks tend to be more magnetic than sedimentary rocks but there is a very wide range of overlap.
How does the Earth& 39;s core generate a magnetic field?
In a sense yes. The Earth is composed of layers having different chemical compositions and different physical properties. The crust of the Earth has some permanent magnetization and the Earth’s core generates its own magnetic field sustaining the main part of the field we measure at the surface.
Marble Rock: Geology Properties Uses
Limestone the source material for marble forms when calcium carbonate precipitates out of water or when organic debris shells coral skeletons accumulates. Marble forms when limestone experiences metamorphism. Usually this happens at a convergent tectonic plate boundary but some marble forms when hot magma heats limestone or dolomite

How does weathering affect limestone? - Internet Geography
How does weathering affect limestone? Weathering is the breakdown of rock by physical chemical or biological processes. Limestone areas are predominantly affected by chemical weathering when rainwater which contains a weak carbonic acid reacts with limestone.

Each call is based upon the feel of the grains that make up the limestone. Robert J. Dunham posted his system for limestone in 1962; it specializes in the depositional material of carbonate rocks. Dunham divides the rocks into 4 important corporations based on relative proportions of coarser clastic particles.
