Extract

In the Geological Magazine for February the limestone-boulders in the Bowland Shales of School Share near Settle were redescribed by Dr. R. G. S. Hudson and the writer, and the conclusion reached that they represented a landslip from a fault-scarp raised along part of the Craven Fault-system during the mid-Carboniferous earth-movement. Whilst that article was in the press the writer became aware that great limestone-boulders occur in the Caney Shale of Oklahoma and that they have occasioned much discussion or even, owing to their size and varied fossils, uncertainty as to the age of the associated beds. His interest was piqued, for he recalled that a close comparison had been drawn by Bisat between the contrast of Bowland Shale (Culm) and Yoredale facies of sedimentation, displayed in the Craven Lowlands and in the Craven Uplands and the Yorkshire Dales, and a contrast in Oklahoma between the sedimentation in the Ouachita Mountains and that in the nearby Arbuckle Mountains.
