The Lherz orogenic lherzolite massif (Eastern French Pyrenees) displays one of the best exposures of subcontinental lithospheric mantle containing veins of amphibole pyroxenites and hornblendites. A reappraisal of the petrogenesis of these rocks has

The calibration of the olivine-spinel geothermometer by Fabries (1979) is commonly adopted by a number of petrologists. But the temperatures calculated in this way for ultramafic rocks are significantly lower than those obtained by the pyroxene geoth

Metamorphism in the Vosges massif is characterized by rocks formed under a wide range of pressures and temperatures: high-pressure rocks (garnet peridotites and eclogites facies rocks) are found together with low-pressure rocks (garnetcordierite stab

Clinopyroxene and orthopyroxene megacrysts with lamellar intergrowths of pyroxenes and garnet rarely survive in pyroxenite layers from the exposed spinel-lherzolite massifs because of the emplacement history into the crust. Such features are remarkab

Upper mantle material can be sampled from two distinctive suites in the North Pyrenean Zone (NPZ) of the Pyrenees. These occur either as ultramafic tectonic slices in the central and western part of the NPZ, or as discrete xenoliths in alkaline magma

Compared to the other ultramafic associations from the French Pyrénées, the small layered spinel-lherzolite bodies scattered around Bestiac (Ariège) all display some unusual mineralogical characters : 1) Kelyphitic assemblages (Opx + Sp ± Cpx) ap

In sodic amphiboles of igneous origin, Fe3+ ions are more abundant than Al3+ in the occupancy of the octahedral sites, even in varieties showing a great substitution of Al for Si in tetrahedral sites. On the other hand the Mg/Fe2+ ratio ranges are mu

An empirical calibration of the spinel-olivine geothermometer (Evans and Frost, 1975) is attempted and applied to parageneses of lherzolitic rocks. In ultramafic complexes, most of the derived temperature estimates range between 700 ° and 850 °C, a

The precambrian postorogenic pluton of the Fort-Trinquet area (Northern Mauretania) is composed by a series of granitic rocks in which amphiboles are the characteristic mafic minerals. Twenty six amphiboles have been separated and chemically analysed

Grandidierite has been found in an alumina-rich hornfels xenolith within the granodiorite stock of Tizi-Ouchen, district of Bejaia, Algeria. Optical properties, electron microprobe analyses and paragenetic data are given ; they are compared with data
