Liberation of selenium from alteration of the Bowland Shale Formation: evidence from the Mam Tor landslide

John Parnell, Liam Bullock, Joseph Armstrong, Magali Perez
Published: 21 August 2018
Quarterly Journal of Engineering Geology and Hydrogeology (2018) 51 (4): 503–508.
DOI: https://doi.org/10.1144/qjegh2018-026
...John Parnell; Liam Bullock; Joseph Armstrong; Magali Perez Abstract The Bowland Shale Formation is anomalously rich in selenium (Se) at levels an order of magnitude greater than other black shales. The Mam Tor landslide, Derbyshire, England, offers an opportunity to measure whether the Se anomaly...

Quantifying creep behaviour of clay-bearing rocks below the critical stress state for rapid failure: Mam Tor landslide, Derbyshire, England

E.H. Rutter, S. Green
Published: 01 March 2011
Journal of the Geological Society (2011) 168 (2): 359–372.
DOI: https://doi.org/10.1144/0016-76492010-133
...E.H. Rutter; S. Green Abstract: The Mam Tor landslide (Derbyshire, England) slips downhill at up to 0.5 m a −1 , and offers an excellent opportunity to study time-dependent creep in mudstones under in situ conditions. Annual surveys show that creep rates increase following heavy rainfall...

...E.H. Rutter; J.C. Arkwright; R.F. Holloway; D. Waghorn Abstract The spectacular Mam Tor landslip, near Castleton, Derbyshire, formed over 3000 years ago on an oversteepened slope left after the last ice age. A section of the Namurian Edale mudstones and overlying Mam Tor sandstones has collapsed...

Movement of the Mam Tor landslide, Derbyshire, UK

A. C. Waltham, N. Dixon
Published: 01 May 2000
Quarterly Journal of Engineering Geology and Hydrogeology (2000) 33 (2): 105–123.
DOI: https://doi.org/10.1144/qjegh.33.2.105
...A. C. Waltham; N. Dixon Abstract The Mam Tor landslide is a kilometre‐long feature in shales and sandstones. The initial slope failure occurred over 4000 years ago as a rotational landslide that developed into a large debris flow at its toe. A road built across it nearly 200 years ago, and now...

Colour enhanced infra-red photography of landslips

Published: 01 November 1984
Quarterly Journal of Engineering Geology and Hydrogeology (1984) 17 (4): ii–v.
DOI: https://doi.org/10.1144/GSL.QJEG.1984.017.04.01
... Abstract The combined effects of geology and geomorphological development at Mam Tor in Derbyshire have produced a series of large and impressive landslips. In 1977 the A625 Castleton to Whaley Bridge road, which crosses one of these slips, was finally closed after further movement displaced parts...
