Question

What is mineralisation? Discuss it mechanism.

Answer 1

A mineral is an inorganic substance that occurs naturally. It has a distinct chemical composition and a distinct crystalline form. Mineralization is a process of converting a substance into a mineral.

In mineralization process, the organic substances (dead) are completely breakdown with the end products being carbon dioxide, water and nutrients.

It is a process in which an organism produces inorganic substance from organic substance. It is done through a chemical transformation in a natural way. In human bodies, mineralization is responsible for growth of bones, teeth etc. These inorganic substances are minerals formed from phosphorous, sulfur, iron, magnesium, manganese, calcium such as clacium carbonate, magnesium sulfate etc. The formation of egg shells is also due mineralization.

Mineralization below earth's surface can occur where there a small places like gaps in the buried bodies of animals and human beings. Minerals from underground water permeate through into the gaps and get deposited there.

Minerals form due to diffusion of water through sediments and buried basalt (lava from volcanoes cooled and hardened).  Important metals are formed in the form of ores due to mineralization process underground in Earth's crust.

High Pressure and high temperatures play important role in mineralization process. Silicates are the largest occurring minerals inside Earth.
