The Carboniferous Period lasted from about 359.2 to 299 million years ago* during the late Paleozoic Era. The term "Carboniferous" comes from England, in reference to the rich deposits of coal that occur there. These deposits of coal occur throughout northern Europe, Asia, and midwestern and eastern North America.

Lignite is geologically the youngest of the coal types. It is soft and brown in color. It is composed primarily of compressed, dehydrated woody material. The fixed carbon content ranges from about 20-35% by mass. This type of coal often is called brown coal. It is used mainly for electric power generation and produces 9-17 million BTU/ton.

Coal was central to the industrial revolution, but in the 20th century it increasingly was superseded by oil and gas. However, in recent years coal again has become the predominant source of global carbon emissions.

The demand of coal increased in the 18 th Century. In 1709, coke was first used in place of wood and charcoal. The first use of coal for lighting purposes occurred in the year 1786 . Since it was the most popular supply of fuel, coal was in immense demand. The coal mining industry was a very profitable one, when production went well (Everett).
