The bituminous black pelite of the Messel UNESCO world heritage site is an exceptional
palaeobiological archive from the Middle Eocene greenhouse climate. The pronounced …

Foulden Maar is a highly resolved maar lake deposit from the South Island of New Zealand
comprising laminated diatomite punctuated by numerous diatomaceous turbidites. Basaltic …

Abstract The sediments from Eocene Eckfelder Maar display a cycle from an initial clastic
stage via organic oil shale deposition to a final clastic stage. Increasing aridity is related with …

Deposition of distal tephra-fall deposits in lake systems with low watershed sediment fluxes
can represent large geochemical anomalies in sediment elemental composition. We …

[en] Phosphate-cemented uranium-bearing lithologies in the Helikian Thelon Formation
occur predominantly in the basal fluvial clastics but also as vein systems in the sub-Thelon …

Evaporites characterize the Lopingian of Europe, but present obstacles for biostratigraphic
analysis. We present a case study for processing the Lopingian Zechstein Group evaporites …

Abstract In the Forez Basin of the French Massif Central, clay-rich alluvial deposits include a
series of red-and green-colored sediments and carbonate cement that record evaporation …

We have analyzed the relative mobility of trace elements in five rhyolitic and two basaltic
tephra layers preserved in both altered and unaltered states, as a means of developing a …

Silicified fossils and authigenic silica are common in ancient seep limestones. Silicification
of calcareous fossils facilitates the preservation of even fine details and is therefore of great …

A complex peatland in Alberta was chosen for a paleoecology and peat chemistry study.
Paleoecology was examined through a macrofossil study. The peatland was subdivided into …
