Trace and major element concentrations of mineral phases present in ETZ-13 (alkaline basalt of the main Ethiopian rift) and glass/mineral compositions in the products of experiments conducted at different P-T-XH2O in an internally heated autoclave using this basalt.

We have carried out experiments on a basalt from the main Ethiopian Rift to assess its pre-eruptive conditions in the magma chamber. The files contain all the analyses carried out on the starting material (basalt) and the products of the experiment, for both the glassy and mineral phases. Several experiments were carried out at temperatures between 1080°C and 975°C, mainly at 2 kbar and under reduced conditions. The age spectrum of the basalt used (40Ar/39Ar) is also presented.
