Abstract

Leg 115 was the first of a nine leg program of investigation of the lithospheric, tectonic, sedimentological and oceanographic history of the Indian Ocean Basin. This leg presents the results of the JOIDES Resolution cruise from Port Louis, Mauritius, to Columbia, Sri Lanka, undertaken in the summer of 1987. The 45 peer reviewed papers, each abstracted seperately are distributed between 6 sections. The first section covers volcanics and tectonics, including volcanism in the vicinity of the Reunion Hotspot, petrogenesis of the basement rocks and geochronology of the Mascarene Plateau. The second section deals with biostratigraphy and palaeontology and concentrates on the distribution and stratigraphic use of Cainozoic calcareous nannofossils. Papers in section 3 reconstruct the palaeoceanography of the region from data on carbonate accumulation and preservation, carbonate compensation depth and oxygen isotope stratigraphy. Section 4 is concerned with sedimentology and sediment geochemistry, with papers on porewater chemistry and carbonate and silica diagenesis, grain size and composition. Section 5 is dedicated to palaeomagnetism and physical properties and includes papers on the palaeoposition of the Reunion Hotspot, magnetostratigraphy, magnetic susceptibility and acoustic properties. Section 6 consists of data reports on site survey, Neogene plankton and foraminifera. Section 7 presents a list of the JOIDES Advisory Groups and the ODP policy. Subject, site and palaeontological indexes are provided. -S.J.Stone
