208 A. R. Horicood — Upper Trias of Leicestershire. 



marl, capped by a hard bed Avhicli I took to represent the upper 

 limit of the Rheetic formation. Above it the ordinary Lower Lias 

 limestones and clays come on ". 



Laminated lumpy shales overlying Tea-green Marls have been 

 exposed in the Midland Railway cutting 600 yards north-west of the 

 station. South of Barrow at Netherfield grey shale and nodular 

 limestone was found with a dip of 12°, accentuated by the Barrow 

 and Sileby fault. At Barrow Hill black shales and a bone-bed 

 overlaid Tea-green Maid. 



To the south, in the Wreake Valley, Lias comes on directly against 

 Red Marl owing to the Sileby and Barrow fault, which causes 

 a displacement of the beds to the west, and in a well-sinking at 

 Ratcliffe Boulder-clay (80 feet) rests on Red Marl, showing they are 

 absent here. The lowest beds of the Lower Lias are seen to the 

 east at Kirby Bellairs, so that the fault runs north of the "Wreake 

 Valley. 



In the boring for water at Melton Rhaetic black shales and 

 a nodular limestone 16 ft. 4 in. thick rest on 247 ft. 10 in. of Red 

 Marl, with sandstone near the base, and gypsum beds. 



At Brooksby Red and Grej' Marls are found up the Wreake 

 Valley, indicating the extension of the Rhaetics so far east. In the 

 stream-side between Queniborough and Gaddesby Grey Marls and 

 mottled clays are exposed, and further south near the village east 

 of the new liall Grey Marls are seen along the slopes. In the 

 brook at Barkby and half a mile from the village Grey Marls are 

 also exposed, as well as in fields. At the ISTew York Farm on the 

 Ridgemere road, black shales were met with for 52 yards. Paper 

 shales have been exposed on the ridge north of the fault at Barkby- 

 thorpe, which makes a bold escarpment. 



At Humberstone the Rhsetic beds have been exposed at various 

 points and pierced by borings and well-sections to the east of the 

 Spinney Hills in the low ground between the latter and Crown Hills 

 from Evington Road to Uppingham Road. The shales were struck 

 in the boring at Lodge Farm (2) and appear in the other adjacent or 

 Crown Hill borings (16 ft. 9 in.), but were absent in the Willow 

 Brook boring. They crop out in the Humberstone drive, where Lower 

 Lias beds succeed them. The well-boring at the Asylum pierced 

 Lias and 20 ft. of Rhsetics with nodular limestone. The nodular 

 septaria were recently met with in a well in Freeman's Road North 

 below river gravels, and the slopes at the junction of Green Lane and 

 Coleman Road are in Rhoetic shales. 



At the top of the Gipsy Lane Pit, on the east side, thin bands of 

 black shales succeed a thick section of Tea-green Marl. At their 

 junction I found Esther ia mimita. In a small pond in a field to the 

 east they are again exposed. Following the hillside they run in 

 a north-east direction to a point just north of the Humber Stone, 

 where in a ditch the line of fault brings the Red Marls against the 

 black shales in the second field on the Humberstone and Barkby- 

 thorpe bridle-road. 



In an excavation for St. Philip's Church 2 feet of Rhsetic shales 

 were encountered beneath 9 feet of soil and drift. In Green
