Title

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

Abstract

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.

Quality and validity

Lineage

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.
