FOLIATED COAL Meaning and
Definition
-
Foliated coal refers to a specific type of coal that displays a distinctive layered or foliated structure, primarily consisting of alternating layers of bright and dull coal. This unique characteristic is a result of the intense pressure and heat that coal undergoes during its formation process.
The bright layers in foliated coal typically contain higher amounts of carbon and possess a glossy appearance, while the dull layers consist of lower carbon content and display a matte or dull surface. These alternating layers are often clearly visible upon visual inspection or microscopic examination of the coal sample. The bright layers are dense and tightly compacted, while the dull layers may be more porous or less compacted.
The formation of foliated coal can be attributed to a several factors, including changes in temperature and pressure conditions during coalification, which is the process of organic matter transforming into coal over millions of years. Additionally, variations in the composition and moisture content of the original organic material, as well as the presence of minerals and other impurities, can contribute to the formation of foliated coal.
Foliated coal is often utilized as an indicator of coal rank or maturity, with the bright layers indicating higher rank or more advanced coalification. It is commonly found in certain coal deposits around the world and can provide valuable information about the geological history and conditions under which the coal was formed.

Etymology of FOLIATED COAL
The etymology of the word "foliated coal" can be broken down as follows:
1. Foliated: The word "foliated" originates from the Latin term "foliatus", which means "furnished with leaves". It is derived from the Latin word "folium", meaning "leaf". The term "foliated" refers to something that has a leaf-like structure or appearance.
2. Coal: The word "coal" has its roots in the Old English term "col", which can be traced back to the Proto-Germanic word "kula". This term referred to charred or burnt material and is akin to the Old High German word "kolo" and Middle Low German word "kol".
Therefore, "foliated coal" can be understood as coal that exhibits a leaf-like structure or appearance, possibly due to layered formations or mineral deposition within the coal.
