Abstract:
At Hole 511, on the margin of Maurice Ewing Bank, eastern Falkland Plateau, successful bottom hole temperature measurements were made at 52.5 and 113 meters below the seafloor. The results show a regular increase of temperature with depth of 0.074 °C m**-1.
Conductivity measurements on core samples, made on board ship and at the Lamont-Doherty repository, gave a mean value of 0.842 W °C**-1 m**-1. The heat flow indicated by these observations is 62.3 mW m**-2 (1.49 HFU), a value that is compatible with the geological evolution of the plateau.
