Beyond a few casual referencesthe literature of the Warwickshire ironstones is scanty.

The CoalMeasures lie in a broad syncline. Along the eastern and north-western edges the strata turn up sharply, but they rapidly flattenout towards the centre of the basin near the Coventry Pits ofthe Warwickshire Coal Company (Fig. 6, p. 53).
