Controls on facies mosaics of carbonate platforms: a case study from the Oxfordian of the Swiss Jura

Strasser, André ; Védrine, Stéphanie

In: Special publication of the International Association of Sedimentologists, 2009, vol. 41, p. 199–213

Modern shallow-water carbonate systems commonly display a complex pattern of juxtaposed depositional environments with a patchy facies distribution (facies mo saics). On ancient carbonate platforms, the reconstruction of lateral facies distribution is often hampered not only by discontinuous outcrop but also by lack of suffi ciently high time resolution. This case study from the Oxfordian (Late...

Cadmium anomalies in Jurassic carbonates (Bajocian, Oxfordian) in western and southern Europe

Rambeau, Claire ; Föllmi, Karl B. (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2006 ; 1858.

The trace metal cadmium (Cd) is a highly toxic element, with adverse effects both on human health as well as on ecosystem equilibriums. Its transfer into the environment occurs by the mediation of natural and anthropogenic processes. Important natural sources comprise volcanic emissions and the biogeochemical weathering of Cd-enriched rocks, such as phosphorites or organic-rich deposits. This...
