Today we continued our multi beam surveying and described and processed the three peridotite dredges from yesterday. At 6pm, we dredged a large, 3000m high, mountain (rises up to 500 metres below sea level) in the north of our area. The hunch was that it might be a large basalt volcano, but no!, once again massive peridotite; with a bioclastic carbonate cap. And the question of the day quickly became, “How do we raise a mountain of peridotite to near sea level?”
