Extended Data Figure 4

a, BSE image showing the area mapped by EDS. EDS maps show the distribution of Fe (b, in green), Ti (c, in blue), and Al (d, in red). Colour-scale values represent X-ray counts per pixel for each energy band in the line type Ka1. During frictional melting of andesite and dacite, selective melting tends to affect the iron-titanium oxides more readily than silicate mineral phases owing to their lower fusion temperature30.
