Material fluxes associated with fluid expulsion at cold seeps and their contribution to oceanographic budgets have not been accurately constrained. Here we present evidence that the barium released at cold seeps along the San Clemente Fault zone may significantly impact the geochemical budget of barium within the basin. Barium fluxes at seep localities on the fault scarp, measured with benthic ...

[1] Level, bench-like platforms edged with scarps facing the interior of the Martian Gorgonum Chaos basin may have formed in conjunction with an ancient ice-covered lake. These benches, however, lack the typical features of shorelines associated with wave and current transport and erosion, such as crescentic embayments, spits, barrier islands, and wave-cut cliffs. Rather, the basin-facing platf...

Introduction: The dichotomy boundary represents one of the most important geological and geophysical features of Mars. We have been assessing the nature of modification processes along the dichotomy boundary at northern mid-latitudes in the Deuteronilus-Protonilus region and have found evidence for extensive regional Amazonian glaciation in lobate debris aprons (LDA) and lineated valley fill (L...

Lineated valley fill (LVF) and lobate debris aprons (LDA) in the Deuteronilus Mensae northern dichotomy boundary region, Mars: Constraints on the extent, age and episodicity of Amazonian glacial events a r t i c l e i n f o a b s t r a c t In order to assess the nature, degradational processes and history of the dichotomy boundary on Mars, we conducted a detailed morphological analysis of a 70,...

Great interest has recently been focused on dating and interpreting alluvial-fan surfaces. As a complement to the radiometric methods often used for surface-exposure dating, this paper illustrates a rapid method for correlating and dating fan surfaces using the cross-sectional shape of gullies incised into fan surfaces. The method applies a linear hillslope-diffusion model to invert for the dif...

The seismic hazard assessment across the densely urbanized region in Sofia Basin Bulgaria can be improved through using fault data, search of which we first aim to attain a better knowledge on past earthquake ground ruptures. Currently focused North-Sofia fault, investigated whether, and how, fluvial system responded displacements at site located near village Gorni Bogrov. At studied site, scar...
