34 An Acconnt of the Great Derbyshire Denudation. 



length the first limestone, before the fault terminates or be- 

 comes too inconsiderable to be readily traced, owing to its 

 no longer deranging the order of the strata on the surface, 

 but has the first limestone on both its sides; and thus it 

 happens, that the third inner raised tract, or mineral-field, 

 consistina; of the four limestone rocks and three interposed 

 loadstone*, and containing about 105,000 acres, has about 

 5 1,500 acres of these on its eastern side, occupied by the 

 three upper limeslones and the toadstones, and the remain- 

 ing 53,500 acres in Deib\ shire and Staffordshire is occupied 

 by the fourth, or lowest limestone rock, in which only a 

 few mineral veins occur among its numerous open fissures 

 and cavtrns. 



In the sketch map which accompanies this, I have shown 

 a smaller, or fouth inner raised tract, on which Bakewell is 

 situated, in great part surrounded by a fault, which 1 have 

 thence denominated the great Bakewell fault. I have se- 

 lected this tract, among other small local raised ones, on 

 account of its approaching in shape and position to the 

 others which surround it, and because it explains several 

 curious appearances of the strata in these parts, which have 

 been, and are still likely lo be greatly misrepresented. 



The fault to which I allude, may be said to commence in 

 the limestone shale on the E. side of Beeley, to pass on the 

 S. side of the village, across the Derwenl and on the S. of 

 Haddon-Hall, continuing across the pastures to theLathkil 

 river about a quarter of a mile above Alport, then turns S. 

 past the W. end of Alport to the upper mill, thence W.S.W. 

 for about one mile, where this fault again turns to the N. 

 and crosses the Bradford river, and proceeding across the 

 Mead(iw-place Liberty, crosses Rubinstye Mine and the 

 Lathkil river above Over-Haddon mill; bears then a little 

 to the east of the north, and crosses the new Bakewell and 

 Buxton road at the rise of the hill, passes the N. end of 

 Bird's-head Mine, crosses the Wye river about a quarter of 

 a mile above Bakewell Cotton Mill, proceeds near to Row- 

 dale, turns E. towards Nether Burchill, then N.E. follow- 

 ing nearly the course of the brook, it continues the same 

 direction until about half a mile E. of Hassop, where it 

 turns lo the E. crosses the Derwent again half a mile above 

 Baslow, and terminates in the limestone-shale in Barbrook 

 Dale, as it began. The western side of this'fourth inner 

 tract being most raised (similar to the third tract) occasions 

 the great elevation of the shale, and its freestone in the 

 hills E. of Bakewell and N.E. of Haddon-Hall; the sudden 

 appearance of the limestone, on which Haddon-Hall stands,
