Le volcan du Yasür, en activité, l'importante plaine de cendres, les fortes densités de population vivant autour contribuent à former un paysage fortement typé. L'occupation du sol apparaît dense mais fortement contrastée, révélant les signes d'une
Phases d'arasion d'un volcan et installation corallienne. Contribution de la morphologie du soubassement volcanique (Atoll de Mururoa, Polynésie française) in Proceedings. Volume 3. Symposia and seminars.
The conditions of reef initiation over the Mio-Pliocene volcanic substrate are discussed. Drill holes 1000 m deep have revealed six carbonate layers intercalated with volcanic material, giving evidence not only of subsidence movements, but also
Petrography of the youngest known Murihiku Supergroup, New Zealand: latest Jurassic arc volcanism on the southern margin of Gondwana in Gondwana Five. Selected papers and abstracts of papers.
Early Cretaceous volcanism and the early break-up history of southeastern Australia: evidence from fission track dating of volcaniclastic sediments in Gondwana Five. Selected papers and abstracts of papers.
Developing on volcanic ash, these soils owe their distinctive appearance and properties to the nature of the soil parent material rather than climate. Not as fertile as once presumed, the soils are no longer capable of sustaining continuous cropping
Coast of the South Island, while a tectonically-controlled basin developed on the east coast of both islands. This early extensional phase was accompanied by volcanism ranging from rhyolitic to basaltic. The Late Cretaceous transgression and pene
Late Quaternary shorelines give evidence of an elastic flexuring of the lithosphere in relation to the volcanic load of Tahiti and Moorea islands. Elastic models are however insufficient to explain all the sea-level data: thermal variations
