Co-rich ferromanganese nodules and crusts were sampled at water depths of about 1000 m on the southern flanks of the Tuamotu Archipelago in French Polynesia. Crusts developed on a hard sedimentary substrate form a continuous ferromanganese encrustati

The Galapagos mounds sea-floor hydrothermal system is at least 300,000 years old and once produced manganese-poor sediments, which nearly blanketed the area of the present mounds field. Present-day mound deposits are limited manganese-rich exposures,

The middle-Paleolithic dwelling place of Mauran, situated in a ten meters high quaternary open-air deposit, has recently been excavated. Preliminary stratigraphical and sedimentological analysis reveal several different climatic phases wich can be re

Tubotomaculum are cylinder-shaped bodies a few centimetres long which can be found in pretty large quantities in the "numidian clays" of the upper Cretacean to Oligocene Mediterranean boundary. We present the observations conducted with electron micr

The sediments of six cores from the Rio Grande Rise side of the Vema Channel reflect major phases in the sedimentary history of this area since Ihe lower Miocene. Cores taken from below the present-day lysocline (approx. 4 000 m) consist essentially

Results of stratigraphy and sedimentology from filling of cave "Soulabé" (Ariège) show four periods. Two of them are certainly from old Würmien. The most important (Würmien I) shows, like in tilling of cave La Calmette (Gard) five climatic stages
