Samples were coarsely crushed in a hardened steel press, then milled to fine powders in an agate planetary mill. For XRF analysis, pressed powder pellets (trace element analyses) were produced from mixing 7 g of sample powder with 12 to 15 drops of a PVA solution (Moviol 8-88). Major elements were determined on fusion beads made from pre-ignited powders which were fused with lithium metaborate flux in a ratio of 1:5. Analysis was carried out at U Leicester on a PANalytical Axios-Advanced XRF spectrometer using a PANalytical SuperQ system with IQ+, WROXI and ProTrace extensions, as the controlling and processing software. ICP-MS analysis at U Leicesteonr used a Thermo iCAP-q quadrapole, along with in-house reference material (WS-1b) and a blank. Samples were prepared as above using a standard HF-HNO3 digestion. Additional samples were analysed commercially by ALS.
