The structural properties of GaN/AlN core-shell nanocolumn heterostructures

22 septembre 2014

The growth and structural properties of GaN/AlN core-shell nanowire heterostructures have been studied using a combination of resonant x-ray diffraction, Raman spectroscopy and high resolution transmission electron microscopy experiments. For a GaN core of 20 nm diameter on average surrounded (...)

Miocene karsts and associated Fe-Zn-rich minerals in Ain Khamouda (Central Tunisia)

2 mai 2012

The karstic system in Ain Khamouda (Central Tunisia) has been briefly exploited for its Pb-Zn mineralization in the first 20 years of the 20th century. Since then, little work has been dedicated to this system, apart from some detailed mineralogical studies. Here we place the Ain Khamouda (...)

Upper Cretaceous feldspars in the Cenozoic Limagne Basin : a key argument in reconstructing the paleocover of the Massif Central (France)

19 janvier 2012

The northern part of the N–S-trending basin of the Limagne graben, located in the northern part of the Massif Central (France), contains Oligocene and Miocene calcareous lacustrine deposits. The area is known for its stromatolite reefs surrounded by marl, clay and uncemented carbonate sand with (...)

Fluid geochemistry of natural manifestations from the Southern Poroto-Rungwe hydrothermal system (Tanzania) : preliminary conceptual model

19 janvier 2012

The South Poroto-Rungwe geothermal field, in the northern part of the Malawi rift, Tanzania divides in two main areas. The relatively high altitude northern area around the main Ngozi, Rungwe, Tukuyu and Kyejo volcanoes, is characterised by cold and gas-rich springs. In contrast, hot springs (...)

Occurence and diversity of lipids in modern coral skeletons

19 janvier 2012

Coral skeletons are composite acellular structures, in which organic macromolecules are intimately associated with mineral phases. Previous studies focussed on proteins and sugars of the soluble organic matrices extracted from the skeletons. Here we report the occurrence of diverse lipids which (...)

Preliminary dating of the Viluy traps (Eastern Siberia) : eruption at the time of Late Denovian extinction events ?

19 janvier 2012

In this short note, we report new age determinations from four samples of the Middle-Paleozoic Viluy Traps in Siberia, east of the more famous Permo-Triassic Siberian Traps. These samples, which were collected from three drill cores, have been analyzed in parallel and independently in the Orsay (...)

Ostracod-based isotope record from Lake Ohrid (Balkan Peninsula) over the last 140 ka

19 janvier 2012

The stable isotope composition of benthic ostracods from a deep-lake sediment core (JO2004-1) recovered from Lake Ohrid (Albania-Macedonia) was studied to investigate regional responses to climate change at the interface between the north-central European and Mediterranean climate systems. (...)

Lessons learned from natural and industrial analogues for storage of carbon dioxide

19 janvier 2012

The deployment of CCS (carbon capture and storage) at industrial scale implies the development of effective monitoring tools. Noble gases are tracers usually proposed to track CO2. This methodology, combined with the geochemistry of carbon isotopes, has been tested on available analogues. At (...)

Toxic levels of metals in Ferralsols under natural vegetation and crops in New Caledonia

19 janvier 2012

The chemistry of soil solutions and the potential toxicity of trace metals (Co, Cr, Cu, Ni and Mn) were investigated on soils formed on ultramafic rocks. Soil solutions were collected along a soil toposequence under natural vegetation and under a cropped field. In the latter, metal speciation (...)

Clay mineral distribution in surface sediments of the northeastern South China Sea and surrounding fluvial drainage basins : source and transport.

19 janvier 2012

Clay mineralogy of surface samples throughout the northeastern South China Sea (SCS) and surrounding fluvial drainage basins has been investigated to reveal source and transport of detrital fine-grained sediments. Three characteristic end-members in clay mineral compositions were observed from (...)

The paleostorm history of coastal lagoon environments (Pierre Blanche Lagoon, central part of the Gulf of Lions) has been established by integrating clay mineralogy and geochemical analysis. Clay mineralogy combined with bulk major and trace elements concentrations allow for the definition of (...)

Late-Holocene evolution of a coastal lagoon in the Gulf of Lions (South of France)

19 janvier 2012

central part of the Gulf of Lions shoreline is characterized by many coastal wetlands that resulted from the interaction between a process of shoreline regularization by migrations of littoral barriers and a slow filling of the back-barrier areas by the riverine and marine inputs.

Geophysical and atmospheric evolution of habitable planets

19 janvier 2012

The evolution of Earth-like habitable planets is a complex process that depends on the geodynamical and geophysical environments. In particular, it is necessary that plate tectonics remain active over billions of years. These geophysically active environments are strongly coupled to a planet's (...)

Implementation Strategies for Hyperspectral Unmixing Using Bayesian Source Separation

23 septembre 2011

Bayesian positive source separation (BPSS) is a useful unsupervised approach for hyperspectral data unmixing, where numerical nonnegativity of spectra and abundances has to be ensured, such as in remote sensing. Moreover, it is sensible to impose a sum-to-one (full additivity) constraint to the (...)
