  Coal - LoveToKnow 1911
Coal then meant the carbonaceous residue obtained in the destructive distillation of wood, or what is known as charcoal, and the name collier was applied indifferently to both coal-miners and charcoal-burners.
The Coal Measures which form part of the Palaeozoic or oldest of the three great geological divisions are mainly confined to the countries north of the equator.
The uppermost portion of the Coal Measures consists of red sandstone so closely resembling that of the Permian group, which are next in geological sequence, that it is often difficult to decide upon the true line of demarcation between the two formations.

The Bainmedart Coal Measures comprise an ~1875m thick sedimentary sequence of repetitive fining-upwards cycles which are dominated by quartzose and feldspathic sandstones, with minor carbonaceous siltstone, coal and claystone.
The period of deposition of the Bainmedart Coal Measures is presumed to have coincided with a relatively wet climate, resulting in high water tables and the formation of laterally extensive forest-mires and lakes within floodbasins.

Coal seams are more or less broken up by faults and hitches, and a greater or less quantity of coal must be sacrificed to the necessities of mining.
The coal measures consist of many alternated beds of sand, mud, coal, and ironstone, deposited during a long interval of time in estuaries, great swamps, fresh-water lakes, deltas, or flat shores, which gradually sank as the beds were added.

The plants of the coal period were not sub-aqueous, but required the influence of the sun's rays to promote their growth, just as we see in the great peat-bogs of the present time.
A single coal bed seldom exceeds five or six feet in thickness; when of greater thickness than this it is apt to contain a parting of fire-clay, which tends to show that it is a double seam, and liable, in other localities, to be separated by many feet of strata.

 Coal
The coal that is often mentioned in the County of Cavan has a somewhat curious history.
