... adakites, with fractionated REE and pronounced negative Eu anomalies; they are comparable to FI type rhyolites of other Archean greenstone belts, likely melts of thick mafic crust at ∼40 km with residual garnet, in an extensional setting. Consequently, the switch from arc basalts and boninites to adakites...

For example, a seismic reflection profile through the high-amplitude...
