Pelagic Sediments - On Land and Under the Sea

About this book

This first "IAS Special Publication" contains the oral presentations from a special symposium on pelagic sediments held in Zurich in 1973. The aim of the symposium was to bring together sea-borne researchers involved with the Deep Sea Drilling Project and land-locked researchers studying ancient sediments.
