The Kletno deposit in the Śnieżnik Massif (Central Sudetes, SW Poland), mined for Fe, U, Ag, Cu, fluorite, and marble through the ages, developed at the contact of marbles and orthogneiss. Here, we present a new Fe-Ti-V-ore (containing up... more
The Mesoarchean Nuasahi chromite deposits of the Singhbhum Craton in eastern India consist of a lower chromite-bearing ultramafic unit and an upper magnetite-bearing gabbroic unit. The ultramafic unit is a ∼5 km long and ∼400 m wide... more
This study reports the composition of the oceanic crust from the 16.5°N region of the Mid-Atlantic Ridge, a spreading ridge segment characterized by a complex detachment fault system and three main oceanic core complexes (southern,... more
The Puy Beaunit maar presents a large variety of mantle xenoliths (spinel peridotites, pyroxenites and layered rocks). A detailed study of the textures and mineral equilibria shows the unusual character of this occurrence and the local... more
Although the structure of mantle plume-derived oceanic plateaus has recently been assessed using remote geophysical techniques combined with petrological modelling, it is nevertheless desirable to test whether these (theoretical) rock... more
Lors de la 2eme campagne de restauration architecturale de Tell Beydar (avril-mai 2004), le demontage d’un mur ancien du temple C a permis la decouverte d’un fragment de bol en pierre, d’apparence inhabituelle. Le prelevement d’un tres... more

The Troodos complex, Cyprus, provides an opportunity to study the structural configuration along a fossil intersection of a spreading axis and a transform fault. We complement studies at Troodos that have reconstructed the brittle... more
An Ediacaran mafic intrusion of south Jordan is a distinctive appinitic igneous rock with a possibly unique texture, characterized by spherical clots up to 40 mm in diameter composed of amphibole cores from which plagioclase euhedra... more
Orthopyroxenes and clinopyroxenes in metabasites in contact with the massif-type Ana-Sira anorthosite yield the following equilibrium temperatures using various geothermometers: 840°C (Wells 1977); 8000 C (Wood & Banna 1973), 650"C... more
