(NERC Grant NE/P00170X/1) 2021-11-07 creation http://data.bgs.ac.uk/id/dataHolding/13607844 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.

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
