Petrology of a Suite of Eclogite Inclusions from the ...

1984-1-1 · The Type II eclogites show a full range of mineral compositions and appear to have evolved toward peraluminous compositions by igneous fractionation. It is inferred that the suite crystallized at pressures of 30 to 50 kbar and temperatures of 1350 to 1550°C, although compositional differences suggest that they may not be related to a single igneous event.

The resulting cataclastic rocks are known as fault breccias, mylonites, or pseudotachylites, corresponding to diminishing grain size. A pseudotachylite is so intensely sheared that it looks like black basaltic glass (tachylite).
