Limitations on Public Access

otherRestrictions

Other constraints

restricted

Other constraints

The dataset has been formally approved by BGS for access by external clients under a BGS Digital Data Licence, issued via BGS's IPR Section. The dataset must not be provided to, or be accessible by, an external client until the IPR Section confirms that signed licence documentation is in place. Refer to the IPR Section (DigitalLE@bgs.ac.) if further advice is required.. Constraint applies until 2022-12-31

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

Zircons from the <300 µm fraction were concentrated using standard gravity settling and magnetic separation techniques. Samples were then mounted in resin, polished and analysed using an Agilent 7900 LA-ICP-MS. Plešovice zircon (Sláma et al., 2008) was used as a primary standard to correct for instrumental mass bias and depth-dependent inter-element fractionation. Approximate U and Th concentrations were calculated by comparison with NIST 612 glass (Pearce et al., 1997). Data reduction of the time-resolved mass spectrometer data was performed using GLITTER 4.5 (Griffin, 2008). Ages younger than 1100 Ma were calculated using the 206Pb/238U ratio whilst older grains used the 207Pb/206Pb ratio. Data were filtered to exclude non-zircons based on zirconium concentrations and a -5/+15% discordance threshold was applied. Final data were processed using IsoplotR (Vermeesch, 2018).
