Core from 800 mbsf

Core sample split in half from 800 mbsf (metres below seafloor)

This core is from 800 mbsf (metres below seafloor) in the Hikurangi subduction zone basin. It has been split in half so geologists can describe it and take samples for experiments. It is mudstone with some nuggets of volcanic debris scattered through it (called basaltic clasts). The fossils in them have been dated to about 40 million years old.
