small spherical pyrites inclusions called "Brazils" and softs. The Middle Hards are a good steam generating coal. The coal forming the top and bottom few inches of this seam were often very poor quality, containing sulphur and forming large amounts of ash. These layers were called "bags" or "dandies" were left in place.
490:
A high quality, low sulphur coal used for coke manufacture and as a manufacturing and household coal. The seam deteriorated to the north and south of the coalfield as it was split by dirt partings. Named after the village where the seam outcropped. The seam consists of three parts: bottom and top

This was the most important seam in the coal field, and 50% of the coalfield's output came from this seam. It was generally 3 m thick. The seams consistency varied from top to bottom. The upper portion was a bright soft coal, the middle portion a hard dull coal known as the "hards" and the

A good quality industrial coal used for gas manufacture that after the
Barnsley seam is the most important in the South Yorkshire Coalfield. This is a three part seam consisting of Tops, Bottoms (used for gas manufacture) and the middle hards. The tops are split into Bright Hards which contain

There are two seams of
Flockton coal, the Flockton thin which is the lowest and generally too thin to work and the Flockton Thick 30 m above the latter. This is a good household and coking coal. The thick seam itself is split in two by a dirt band, often 1 m thick.

The list of coal seams that follows starts at the shallowest seam and proceeds downwards with the outcrops occurring progressively further west until the deepest coal seam, the
Silkstone Seam which outcropped at the western edge of the coalfield.
309:
The quality of this coal seam varied but it generally provided a household and gas coal and was some times used as second class steam coal. The seam was often split by dirt partings. The better quality coal was found north of
Barnsley.
295:
Between the
Barnsley Seam and the Swallow Wood seam numerous thin seams of coal are found. To the south and east of Barnsley these coalesce to form the Dunsil seam, a poor quality coal with a high ash and sulphur content.

A good quality low ash coal that was used for steam raising, gas and house coal. The smalls were used for coke manufacture. The seam, whilst extensive over the coalfield, was often split by dirt partings.

A gas & coking Coal. The seam is often split by a "spavins", thin layers of earthy clay with rootlets or larger partings of shale. This often results in two distinct seams called High and Low Fenton.

and the Abdy seam south of the town. A household coal with a low sulphur content which was not mined extensively because the roof of the seam was often a shaly mudstone which made mining it difficult.
252:
This thin band of coal lies 15 to 30 m above the main
Barnsley Seam and is not often worked. The seam is generally split by dirt and clay partings and the coal itself often contains pyrites.

Coal suitable for gas and coke production. The seam consists of two parts the "tops" and the "bottoms" split by a dirt parting. The seam is very variable and seen little south of
Barnsley.
