The data was collected over a period of about two years in two different laboratories (University of Manchester and University of Bristol) using multi-collector ICPMS techniques. A description of the methods used to obtain the W and Mo isotope data can be found in Willbold et al. (2011) and Willbold et al. (2016). The determination of the Pb isotope data is detailed in Freymuth et al. (2016). The data of reference materials (standard solutions and geological reference materials) is used to assess the reproducibility and accuracy of the mass spectrometric setup at the time and used as uncertainty estimate for the geological sample data.
