Thermal and microwave paleointensity data measured at the University of Liverpool on natural clinkers from Montana, USA, vitrified fort and volcanic material from Scotland, and volcanic material from the Yandiniling Dike Swarm, Australia

All paleointensity data gathered from the project at University of Liverpool. The data is divided into multiple four letter coded sections which refer to a specific locality and/or experiment type. The sections are as follows: CFEH - Thermal paleointensity experiment on natural clinkers from Montana, USA, looking primarily at the Epsilon Hematite phase, with an additional high-power alternating field demagnetisation step after each infield step of the experiment. LPRM - volcanic material from Kinghorn and Wormit Bay, Scotland (335 and 410 million years old). This was a specific experiment with samples given a prior high temperature applied field of 80 micro Tesla and a pressure remanent magnetisation of 80 micro Tesla. VFSS – a microwave paleointensity experiment carried out on Scottish vitrified fort material, sampled in the 1980s. WTBY – microwave paleointensity experiments carried out on Scottish volcanics from Wormit Bay. Sampled September 2015. YDSR – volcanics from Yandiniling Dike Swarm, in Yilgarn Craton, Australia, 2.6 billion years old. Sampled Nov 2018. Sampled with Yebo Li from the University of Curtin (Perth) as part of a collaboration, resampling of 16WDS sites from his palaeodirections paper. These were microwave demagnetisation (specimen orientation only) and paleointensities. NERC grant NE/P00170X/1.

Other constraints: Either: (i) the dataset is made freely available, e.g. via the Internet, for a restricted category of use (e.g. educational use only); or (ii) the dataset has not been formally approved by BGS for access and use by external clients under licence, but its use may be permitted under alternative formal arrangements; or (iii) the dataset contains 3rd party data or information obtained by BGS under terms and conditions that must be consulted in order to determine the permitted usage of the dataset. Refer to the BGS staff member responsible for the creation of the dataset if further advice is required. He / she should be familiar with the composition of the dataset, particularly with regard to 3rd party IPR contained in it, and any resultant use restrictions. This staff member should revert to the IPR Section ( ipr@bgs.ac.uk) for advice, should the position not be clear.

Statement: Paleointensity experiment - stepwise treatment of samples in both zero magnetic field and a known applied magnetic field to determine paleointensity. THI - thermal paleointensity where samples are heated in zero or applied fields and measured on multiple magnetometers as indicated in data files. MW - microwave experiments where samples are exposed to different powers of microwaves to demagnetise them, both in zero and applied fields.
