Yemen Trap Series | John Seach


The Yemen Trap Series is located on the plateau of Yemen. It is one of the largest outcrops on the Ethiopian-Yemenitic plateau.

The series is related to tectonics in the Afro-Arabian plate.

The first phase of activity occurred between 26-30 Ma and produced alkaline to transitional basalts with some ryholite iginimbrites.

The second phase of activity between 19-23 Ma, rhyolites and some transitional basalts were erupted in the south and southwest of the area.
