Lignite thin section slide. Lignite coal and indeed all other varieties of coal are classed as organic sedimentary rocks. It has a high carbon content 25 - 35% & a moisture content up to 66%. The high volatile content makes it easier to convert into gas and liquid petroleum products than higher ranking coals. Often referred to as 'brown coal', it forms due to the compression of peat material. Having been under minimal compression in comparison to the higher grade coals i.e. bituminous and antracite, coarser material and plant matter is often preserved in lignite rock, this is reflected in the thin section. The slides are 30 microns thick and measure 46 x 27 mm in size and have a cover slip of the section along with a protective cardboard sleeve.
