“…Combining the Anglian and post-Anglian incision rates gives a rate of 0.055 mm a -1 , which corresponds reasonably closely with longer term uplift rates, e.g. 0.03 to 0.06 mm a -1 (post Late Miocene uplift) determined by Pound et al (2012), but is clearly lower than the rates suggested by Westaway (2012) for the Quaternary. Banks et al, (2012) presented the incision rates in components, because it was considered that they may contribute to future assessments of crustal movements, operating over differing time-scales and wavelengths of uplift, i.e.…”

We thank Westaway (2012) for his interesting discussion of the uplift rates derived from the Alport tufa and its geomorphological setting. His comments highlight the tentative nature of geological approaches to determining rates of glacio-isostatic and tectonic uplift. In particular, Westaway (2012) questions the validity of the uplift rates that were presented within our original paper (Banks et al., 2012) and we welcome the opportunity to clarify this further. We also welcome the opportunity to comment on the practicalities of determining uplift measurements from karst environments within the wider, long-term, tectonic evolution of the Peak District.Westaway (2012) makes reference to two (of four) cited incision rates (Banks et al., 2012) that correspond with the Late Ipswichian to Holocene period, and the end of the Anglian to present and compares them with values that span the entire Quaternary (Westaway 2009(Westaway , 2012. Accordingly, it should be noted that the uplift rates that were presented by Banks et al. (2012) were linked to specific durations, which also included periods of accelerated down-cutting during the Devensian to Holocene (0.165 mm a Based on geodynamic modelling Westaway (2009 and 2012) presents a case for on-going hot-spot related lowering of viscosity in the lower crust as the driver for lower crustal flow coupled to surface process and resulting in elevated rates of uplift in northern England. This contrasts with the Shennan et al. GIA model, which assumes an elastic lithosphere and viscous structure within the mantle. Modelling undertaken by Westaway (2009) uses observed uplift that is, in part, estimated from "karstic base-level lowering". Calculation of uplift rates in karst environments is particularly difficult. This is due to the paucity of dated surfaces and the hydrogeological complexity largely due to the solubility of limestones, which facilitates subsurface flow at the expense of surface flow. Accordingly, Westaway (2009Westaway ( , 2012) is forced to draw from an extensive literature review of karstic levels, using speleothem dating as the basis for calculating uplift rates. It is assumed that the dated karstic levels

“…Lloveras et al 2011). Plant studies are dominated by palynology, either for dating of infilling sediments (Higgs & Beese 1986;Higgs & Jones 2000;Simms & Boulter 2000;Pound et al 2012) or to reconstruct local environmental history in Quaternary cave sequences, in particular those of interest to archeologists (Weinstein-Evron et al 2013). Reports on the record and preservation of megascopic plants or invertebrates are nearly nonexistent (Camacho et al 2000;Moldovan et al 2011;Worobiec 2011).…”

Karstification produces a unique and spatially complex architecture of accommodation space for the accumulation of later sediments. The sedimentary record within caves can act as a repository for stratigraphic and palaeoenvironmental information that has been locally removed by subsequent surface erosion. Caves and karst also allow for the preservation of biota not usually found in the fossil record. Pennsylvanian palaeokarst from Illinois, USA, illustrate the potential of ancient caves as a home for 'lost stratigraphy'. These palaeocaves have dissolutional features associated with contemporaneous sediment influx (paragenesis), indicating that speleogenesis and cave sediment deposition were synchronous. These features also provide evidence of changing water tables. The fill within the caves suggests multiple flood events on the surface. The enclosed biota contains rare upland plants, such as conifers, as well as scorpions. Both plants and animals preserve original organic constituents. The presence of charcoal, as well as diagnostic polyaromatic hydrocarbons, point to wildfires and thus dry episodes on the land surface. The cave fills are outliers from correlative formations in the region. The filled voids of these ancient caves thus fill palaeontological, palaeoenvironmental, and stratigraphic gaps.

“…Boulter and Chaloner (1970) proposed a Pliocene age for this unit, which had been previously attributed to the Carboniferous, Permian and Triassic. The age of the Brassington Formation was subsequently revised to Miocene-Pliocene (Boulter 1971) and, more recently, to Middle-Late Miocene (Pound et al 2012;Pound and Riding 2016;Walsh et al 2018).…”
