Dataset supporting the University of Southampton doctoral thesis "Using cumulates as an insight into explosive volcanic eruptions and a geochemical understanding of the magma reservoir below Tenerife" by Emma Horn.

This data set contains two spreadsheets and one ‘Read Me’ file giving an outline of each of the data spreadsheets. The dataset contains petrographic and geochemical data relating to Chapter 4 of the PhD thesis; modal abundance data, major and trace element chemistry for the Tenerife juvenile nodule sample collection. The second dataset contains fieldwork data on the abundance, size and composition of lithic and juvenile clasts present in the lithic-rich breccia of the Ravelo unit of the Fasnia Member.
