Among the various uses of coal, thermal power generation is the most important. iii Domestic fuel In cooler regions, where room heating is necessary, coal is very useful. In under-developed and developing countries of Asia and Africa, coal still provides bulk of the fuel in domestic cooking. Use of coal for this purpose is now being reduced.
Coal - Coal - Coal types Coals contain both organic and inorganic phases. The latter consist either of minerals such as quartz and clays that may have been brought in by flowing water or wind activity or of minerals such as pyrite and marcasite that formed in place authigenic. Some formed in living plant tissues, and others formed later during peat formation or coalification.

The coal formation process involves the burial of peat, which is made of partly decayed plant materials, deep underground. The heat and pressure of burial alters the texture and increases the carbon content of the peat, which transforms it into coal, a type of sedimentary rock. This process takes millions of years. Types, or ranks, of coal are determined by carbon content.
These rocks are further sub-divided into types. Though all rocks look similar, they have different physical and thermal properties. We have organized information in a tabular form where you will find the origin, discoverer of all the types of rocks, list of their colors and textures and many unique and intriguing facts about Rocks in Africa.
