influence of magnetic field. The magnetic properties of rocks arise from the magnetic properties of the constituent mineral grains and crystals. Typically, only a small fraction of the rock consists of magnetic minerals, and hence this small portion determines the magnetic properties and the magnetization of the rock .

Apr 24, 2017· Igneous rock, also known as volcanic rock, is formed by the cooling of magma or lava. This type of rock is classified by cooling time and the type of magma it is formed from. The properties of these rocks vary greatly, including their chemical composition, grain structure, texture and color.

The feldspar and olivine changed to a finegrained serpentine. It will attract a magnet and this characteristic is considered a positive means of identification. Scientists have estimated the age of Cumberlandite to be about one and onehalf billion years when a small volcano erupted and 24 different minerals mixed together with molten rock and when it cooled formed a slightly magnetic rock that is .

Granite is the most widespread of igneous rocks, underlying much of the continental crust. Granite is an intrusive igneous rock. Intrusive rocks form from molten material (magma) that flows and solidifies underground, where magma cools slowly. Eventually, the overlying rocks are removed, exposing the granite.
