Beds, and is the same as a bed seen in the brickj^ard at Hathern. The 

 bed exposed in the cutting of the Great Central Railway to the east 

 is probably on a higher horizon and may represent the Dane Hill 

 Sandstone in an attenuated form. In the brickyard there is a section 

 63 ft. 7 in. of red and green and white marl with two thick skerries 

 and thinner green bands, with ripple-marks. 



A boring in the brickyard passed through 48 feet (dug well), Eed 

 Marl 228 feet, sandstone and marl 126 feet, and ended in Forest 

 rocks. In a second boring south of the village, below 110 feet Red 

 Marl and 140 feet Lower Keuper Sandstone, 256 ft. 4^ in. Bunter 

 and 362 feet of Carboniferous Limestone Shales and Millstone Grit 

 were met with. 



In regard to the Bunter limits, Fox-Strangways considered " they 

 were not deposited much to the east of a line drawn through Castle 

 Donington and Ashby, though the boring at Hathern shows that they 

 were abnormally thick in what is now the valley of the Soar". 

 De Ranee remarks, "The eastern boundary of the outcrop of the 

 Pebble Beds of the Bunter ranges along the River Trent, past 

 ]S'ottingham, as far as Stanton and Swarkeston. Eastward of this 

 line the Keuper Sandstone rests on the Coal-measures of Ashby- 

 de-la-Zouch and the Carboniferous Limestone of Breedon Hill. 

 Ranging parallel to this line and eastward of it, the Lower Keuper 

 Sandstone building stones and conglomerate thin out, being last met 

 with at Hathern, ranging north of Charnwood and Atheistone. Soutb 

 of Nuneaton fine-grained white sandstone used for building occurs, 

 interbedded with evenly bedded shale of the waterstones." 



Horace Brown remarks that the Permian too, in Leicestershire, is 

 not met with east of Packington. There is thus abundant evidence 

 that the Trias deposits overlap each other in all directions, the newer 

 divisions transgressing upon older rocks beyond the area of the newer 

 divisions, indicating a considerable subsidence during this period. 

 Whilst the Lower Keuper is slightly thicker in some directions to 

 the south-east it attains its maximum at Hathern, and though there 

 is a south-easterly attenuation of the Trias generally around the 

 older rocks there is, especially in this area, a thickening of the 

 deposits eastward, borings at Leicester showing a thickness of over 

 600 feet. 



The borings at Piper Wood, north of Shepshed, are difficult to 

 correlate, but there appears to be here, as at Hathern, underlying 

 the Red Marl a considerable thickness of Millstone Grit, and possibly 

 Carboniferous Limestone Shales. Taken with the outcrop of Millstone 

 Grit at Castle Donington, it would seem that there is an anticlinal of 

 the Carboniferous rocks, perhaps, related to an older anticlinal of 

 Charnian rocks running north-west by south-east, and to this we may 

 attribute such evidence as there is of flexures in the Red Marl, 

 forming the Diseworth inlier. This was produced in post-Triassic 

 times along a fold which had previously, and has since, been subjected 

 to renewed activity. Between here and Loughborough much more 

 drift obscures the Red Marl, and exposures are few. Here the Red 

 Marl is thicker and dips south-east at a low angle. In a few brick- 

 vards in the town the marls are used for brick- and tile-making, but
