Nottingham Excursion, May, 1913

Page 5 P805005 The Vale of Belvoir. Ironstone Quarry Stonepit Houses near Wartnaby. Nottingham Excursion, 10th May 1913. Middle Lias Ironstone. This ironstone is of the same horizon as the celebrated Cleveland iron ore which belongs to the Marlstone or upper part of the Middle Lias.
Page 5 P805006 The Vale of Belvoir. Ironstone Quarry Stonepit Houses near Wartnaby. Nottingham Excursion, 10th May 1913. Ironstone overlaid by Boulder Clay. This Ironstone is of the same horizon as the celebrated Cleveland iron ore which belongs to the Marlstone or upper part of the Middle Lias.
Page 5 P805007 The Vale of Belvoir. Ironstone Quarry Stonepit Houses near Wartnaby. Nottingham Excursion, 10th May 1913. Step-fault in Ironstone with 'Roche Moutonnee' surface. The hollow was originally filled with Upper Lias Clay which has to be removed together with the Boulder Clay before the ironstone can be used.
Page 5 P805008 The Vale of Belvoir. Ironstone Quarry Stonepit Houses near Wartnaby. Nottingham Excursion, 10th May 1913. Method of working the ironstone. All the clay and top hamper is wheeled across these boards and deposited on the opposite side as the ironstone is removed in the rail trucks, thus causing a flat surface but at a lower level than before.

Added note: Satin spar is a special kind of fibrous gypsum which is remarkably translucent and at present is quarried in only one place viz East Bridgford. Fibrous gypsum is not sufficently translucent.

Page 27 P805050 Nottingham Brick Co. Carlton Road. Nottingham Excursion, 14th May 1913. Skerry in Keuper Marls. The thin bands of sandstone are locally known as skerries. When several bands are close together and divided by narrow beds of shale as seen at the top of the section it forms a 'skerry belt' causing a plateau surface.
