A study of the anchizone-epizone metamorphic transition
(University of St Andrews, 1990-07) - ThesisThe offshore Karoo Supergroup (+2 km thick) of the Seychelles has been divided into five members based mainly on sandstone/mudstone development as revealed by wireline logs and lithological samples. The four lower members ... -
