The dynamics of soil moisture and temperature states are forced by land surface fluxes that form the coupling between the soil and the atmosphere. This twoway interaction between the soil and the atmosphere results in feedback mechanisms that affect the temporal patterns of variability of the system. To understand these characteristics of soil moisture and temperature variability, a one-dimensi...

Deciphering the exhumation mechanism of high-pressure−low-temperature (HP-LT) metamorphic rocks can provide important insights into tectonic evolution oceanic subduction zones at active continental margins. Here, we present a multidisciplinary study examining tectonics Permo−Triassic eclogite-bearing HP-LT terranes Central Qiangtang belt (CQMB) in central Tibetan Plateau. Field geological relat...

Les références principales pour l’interprétation du produit de mélange de deux séries en termes d’automates et les applications aux identités syntaxiques sont [Lo 2002] 1.3 et [J 1980]. Dans le cours du 14 mars les exemples suivant sont traités: 1. Mélange de deux éléments de K < X > 2. L’identité x∗0x(x1 · · ·xn) = x∗0x1x∗0x2 · · ·x∗0xnx∗0 3. L’identité (x0 + x1)∗ = x∗0xx∗1 4. L’identité (1 + ...

RÉSUMÉ. L’idée à l’origine du modèle de mélange conjoint (MMConjoint) est de classer simultanément deux ensembles d’observations en introduisant un a priori conjoint entre les deux classifications et un lien statistique entre les deux observations. Nous étudions en particulier le cas de mélanges gaussiens et le cas de mélanges paramétriques non gaussiens construits à partir de copules et de mar...

Ž . Gabbroic sills intruding dunite in the crust–mantle transition zone MTZ of the Oman ophiolite have textures and compositions very similar to those in modally layered gabbros that form the lower part of the gabbro section in the ophiolite, and different from those in non-layered gabbros near the dike–gabbro transition. The presence of gabbroic sills in the MTZ indicates that modally layered ...

This paper reports the effect of chronic high fluoride exposure on children`s intelligence quotient (IQ). In this cross sectional study, two urban communities with similar socio-economic and cultural status but with different levels of fluoride in drinking water, in Kerman province of Iran were studied: Koohbanan City (fluoride 2.38 mg/L), Baft City (fluoride 0.41 mg/L). Study samples consisted...

Fluid inclusions and geological relationships indicate that rodingite formation in the Asbestos ophiolite, Québec, occurred in two, or possibly three, separate episodes during thrusting of the ophiolite onto the Laurentian margin, and that it involved three fluids. The first episode of rodingitization, which affected diorite, occurred at temperatures of between 290 and 360 degrees C and pressur...

Gold has been found in the Cyprus-type volcanogenic massive sulfide ore (VMS) deposits of Corchia ophiolite (Parma province, Italy) in the Cantiere Donnini, Speranza and Pozzo mining sites. At Cantiere Donnini and Speranza, the mineralization occurs at the contact between pillow lava and sedimentary rocks. The Pozzo mineralization is hosted by a serpentinite. Concentrations of gold up to 3070 p...

7 The Unst Ophiolite is the best exposed of a chain of early Ordovician ophiolites in the 8 Scottish Caledonides and is widely regarded as having formed in a supra-subduction zone 9 setting within the Iapetus Ocean. Reinterpretation of sheeted dykes suggests that it formed 10 as an oceanic core complex, presumably during subduction roll-back immediately prior to 11 obduction onto the Laurentian...
