Thermal and Alternating Field demagnetisation data from Viesan-age carbonates from the Meathop quarry section, Cumbria sampled in 2018, measured at the University of Lancaster. (NERC Grant NE/P00170X/1)
Thermal and Alternating Field demagnetisation data from Visean-carbonates from Meathop Quarry sampled in 2018. This covers the Martin Limestone Formation. MQ are sample codes sampled and data collection carried out by Tereza Kamenikova and Dr Mark Hounslow. The AF demagnetisation data flagged with a *G has a GRM correction applied along the lines described in Stephenson (1993). Data measured on a 2G instruments RAPID, with blank correction as in Hounslow(2019). File for of demagnetisaon data in in header and also described in the GM4Edit software (Hounslow et al. 2019). Sub-samples from main sample given codes like MQ2.1, MQ2.2 etc Hounslow, M.W. 2019. GM4Edit (v.5.6) - a windows program to manage, plot, export and manipulate palaeomagnetic magnetometer datasets. http://dx.doi.org/10.13140/RG.2.2.31877.91361/1.

Data Quality
One to three specimens from each sample were treated to stepwise thermal demagnetisation, in 25–50 °C steps up to 700 °C Low frequency magnetic susceptibility (Klf) was monitored after heating stages, measured using a Bartington MS2B sensor to assess thermal alteration. Most specimens were treated with a combination of thermal and alternating field (AF) demagnetisation at Lancaster using static axis-AF demagnetisation on a 2G RAPID magnetometer, with GRM correction using GM4Edit (Hounslow, 2019). This combined procedure was to better isolate the remanence in those which were subject to thermal alteration, which started ~250–350 °C
