This dataset is an additional sample list, as an Excel spreadsheet, providing details of the major sample suites collected by Delia Cangelosi during SoS RARE and not added to the master spreadsheet (https://webapps.bgs.ac.uk/services/ngdc/accessions/index.html#item165705) It includes location details and descriptions for rock samples collected in China and Namibia. Most material is still held by the institutions that did the work, as recorded in the sample list.
