In this work we analyse the origin, transport, and deposition processes of pumice fragments up to 30 cm in size, deposited in the Northern Patagonian Foreland more than 200 km from the Andean volcanic arc. ABSTRACT There are numerous studies analysing volcaniclastic supply to continental environments in distal areas from source volcanoes.

European Arid Anomaly Explained With Southward Drift of Eurasia During the Late Jurassic Polar Shift
Abstract The sedimentary successions of several basins in Europe show evidence of widespread Late Jurassic aridification that is considered a long‐standing conundrum in paleoclimate modeling. The distinctive feature of this event is that it appears concentrated in a discrete time interval between the Kimmeridgian (Late Jurassic) and the Berriasian ...

An assessment of latest Cretaceous Pycnodonte vesicularis (Lamarck, 1806) shells as records for palaeoseasonality: a multi-proxy investigation [PDF]
In order to assess the potential of the honeycomb oyster Pycnodonte vesicularis for the reconstruction of palaeoseasonality, several specimens recovered from late Maastrichtian strata in the Neuquén Basin (Argentina) were subject to a multi-proxy ...

ABSTRACT Turbidity current behaviour is affected by interactions with seafloor topography. Changes in flow dynamics will depend on the orientation and gradient of the topography, and the magnitude and rheology of the incoming flow. A better understanding of how unconfined turbidity currents interact with topography will improve interpretations of the ...
