Amphibolite-facies rock composition, Appendix B data for \"A reference Earth model for the heat producing elements and associated geoneutrino flux\"

This dataset is a compilation of chemical composition of global distributed amphibolite-facies rocks. Both meta-igneous and meta-sedimentary rocks are included. The goal of this compilation is to estimate the average composition of middle continental crust, where the temperature and pressure is close to amphibolite-facies metamorphism condition.
