Measurement of rates of surface lowering of limestone in the southern Pennines: an example in the Wye catchment, Derbyshire, UK

Abstract

Measurement of the differential denudation between chert and limestone in a Carboniferous limestone sequence that was cut during excavations for a railway tunnel (in 1865) has provided a means of assessing limestone dissolution rates in a valley side setting in the southern Pennines over the last ~150 years. Dissolution rates of 0.035 mm/ annum have been determined. This rate falls within the range of previously determined limestone dissolution rates in the UK, which have been described in the context of different methods of measurement and the difference in denudations rates over time.

Karst hazard assessment in the design of a residential complex in Moscow

“…First of all, it concerns the estimation of cavity growth rate in soluble rocks (i.e., their dissolution rate), which has recently been persistently cultivated as a necessary element of karst hazard assessment [17]. This criterion has not been evaluated for two reasons: firstly, it is meaningless in relation to limestones that have very low dissolution rates, and secondly, such an evaluation can only be correctly carried out experimentally in the field [18] or laboratory [19], which in these circumstances is difficult and time-consuming.…”

“…Clearly the PGA is making a significant contribution to this field of Earth Science research with a substantial body of new information and ideas.The PGA has a long tradition of publishing important work on aspects of Quaternary geology and climate change in the form of building-block papers that underpin the subject, and this tradition is continued in the issues considered here. Methodological papers includeFindlater et al (2014) who use sodium and strontium in mollusc shells to help determine the palaeosalinity and palaeotemperature of the Middle Pleistocene of eastern England;Collins et al (2014) who present an illustrated guide to the cirripedes from the Plio-Pleistocene of East Anglia, andBanks and Jones (2014) who report the results of measurements on the rates of surface lowering in limestone terrain in the southern Pennines. Within the classic Quaternary stratigraphy modeMurton et al (2015) provide the latest information on the interglacial and periglacial climates and environments of Marine Isotope Stages (MIS) 7 to 5 in south Midland England.…”
