| Mineralogical analyses of sediments from the Makassar Strait, collected during the Corindon and Misedor cruises (dredges, piston and box cores) show the existing differences between sediments supplied from Kalimantan in the West and sediments supplied from Sulawesi in the East. The Kalimantan source is characterized by quartzitic sand, with rare feldspars, heavy minerals consisting mainly of pyroxene (hypersthene) and amphibole and predominant illite-kaolinite in the clay mineral assemblage. In contrast, the Sulawesi source differs by a great abundance of feldspars, lithoclasts and micas with predominant amphibole and pyroxene (augite) and major illite-chlorite clay minerals. |

| During the PROGEMA I cruise which took place on the south-western Pacific coast of Mexico (between 14 degrees and 16 degrees N, 92 degrees and 96 degrees W), 3.5 kHz echo-sounding profiles, surface samples and cores as well as hydrological and oxygen minimum measurements down to 2250 m water depth were made in the Gulf of Tehuantepec. Chemical, sedimentological, mineralogical, X-ray and BEM analyses of waters, core and surface samples provided new data which permit a better knowledge of the Gulf of Tehuantepec margin, where tectonic activity is due to an active subduction. On the shelf of the gulf, the distribution pattern of quaternary deposits is affected by a double tectonic forcing and by eustatic oscillations of the sea level. The first tectonic... |

| The aim of this oceanographic cruise, included in this GIS MISEDOR project was to study the distribution and evolution of the organic matter in the Strait of Makassar, within a distance ranging from the Mahakam delta to the abyssal plain. The particularity of the strait lies in its morphostructural aspect and climatic trend. It is a half-closed basin situated at the far end of the Asiatic (passive margin of Borneo) and Indo-Australian plates (active margin of Sulawesi). Its geographical proximity to the Equator accounts for the very few climatic variations during the Quaternary, a period characterized only by glacio-eustatic fluctuations of the sea level. |

| Corings have been obtained during the Misedor Cruise in the Strait of Makassar (Indonesia). Previous works showed that Recent Quaternary sediments originated from Kalimantan and Sulawesi. These deposits are associated either with settling processes or with paleogeographic events related to eustatic variations. At low sea level, gravity flow from Kalimantan supply deep-sea zones where deposits are arranged locally in stratodecreasing successions. During the rise of the sea level, inputs change both qualitatively and quantitatively. In addition to river-borne inputs (Mahakam), one can observe reworked sediments originating from the continental shelf in the course of its immersion. At high sea level (Holocene) inputs issued from Kalimantan contribute to the... |

| Biomarker data associated with isotopic curve partial differential super(18)O served to establish a stratigraphic scale and thereby a chronology of fluctuations in the circulation and sedimentation of the Kalimantan continental rise throughout the last climatic cycle. During the glacial maximum, period of low sea-level sediments were deposited by turbidity currents originating from Kalimantan. During deglaciation, during rise of the sea-level and more particularly in the Holocene, material issued from Kalimantan either contributed to the building of the Mahakam delta or was dispersed over the shelf. Sulawesi inputs, less abundant and mineralogically different from Kalimantan material, were observed onto the Kalimantan rise. During this same period,... |
