 Upper Keuper Tea-green Marls

A section on the west side, north end, showed Red Marl on one 

 side of the fault with two skerries below a thick bedded sandstone 

 above. Tea-green Marls are shown squeezed in between this, and 

 the Ilhsetic and Lias. Another section showed Lias with two beds of 

 limestone at the Loughborough or south end of the tunnel, rising to 

 the north above Upper Rhsetics with a band of White Hnr below, 

 and Lower Rhsetic beneath it. 



An interesting suite of fossils was obtained here (see Palaeontology). 

 Mr. W. T. Tucker found a piece of bone-bed, 2 inches thick, " stuffed 

 full of bones, scales, and similar to the Aust breccia." About 10 feet 

 above the Tea-green Marls a fish-band was found, also coprolites, 

 vertebrae, and teeth. He also noticed a nodular band 30 feet below 

 the first Lias grey nodular band, with 20 feet black shales beneath it. 

 If so, the Rhsetics here were 50 feet thick. 



At the junction between the Tea-green Marls and the black shales 

 there was a yellow band, but no regular bone-bed. The Tea-green 

 Marls showed traces of erosion. At the north end of the tunnel the 

 dip was 6° to the south. At the south end it was 2°-6°. 



To the east at Costock at Elint Farm in the stream section flinty 

 limestone is exposed, and some pits about here were formerly worked 

 for limestone. To the soutli at Rempstone flinty limestone occurs at 

 Sutcliffe Hill, and where the outcrop crosses King's Brook. The 

 Stanford fault shifts the outcrop again to the west, and about 

 Stanford Hall in the trough high ground is probably formed bj' these 

 beds. Between Walton and Barrow, in the valleys cut through the 

 Drift and Lower Lias, the Bhsetics have been exposed on each side 

 of the brook, and the outcrop is continuous between here and Walton, 

 black shales being struck in a well 500 yards west-south-west of 

 Walton Church. The outcrop continues westward from here to 

 Barrow Hill. 



H. B. Woodward ^ recorded the occurrence of Rhsetics at Barrow- 

 on-Soar, and remarked that " above the black shales there was 

 a considerable thickness of apparently unfossiliferous grey earthy 



Ansted (1866) noted them earlier.
