L'évolution magmatique est étudiée en relation avec l'évolution tectonique globale de la région. Passage d'une tectonique de compression depuis 180 MA à un régime extensif actuellement.

Magmatic and metamorphic events, imprinted in the crystalline rocks of the so-called core mountains inside the Alpine structure of the Inner Carpathians, allow the re-construction of the history of the Rheic Ocean opening, its development and its
final closure. All magmatic suites, mafic and felsic, present in the Carpathians core mountains, show similarities to those found in the European Variscan Belt. All described- and dated metamorphic and magmatic events also have equivalents
in the evolution of the Caledonian-Variscan Belts of Europe. The Carpathian core-mountains, currently dispersed inside the Alpine mountain chain, can be considered the broken fragments of the eastern prolongation of the Variscan orogenic belts – possibly part

Evidence for variability of magmatic processes and upper mantle heterogeneity in the axial region of the mid-atlantic ridge near 22 and 36 N

Interactions between magmatism and tectonics in Iceland : a review
Magmatism and tectonics in Iceland. Special issue
Iceland is often assumed to be a good analogue to study the oceanic ridges. This short review highlights strong differences in terms of deformation pattern and magmatism distribution. These differences come from the large magma supply induced
and oceanic rift and thus remains the perfect object to analyse the interactions between magmatism and extension.

Tholeiitic basalt-rhyolite magmatism and massive sulphide deposits at Matagami, Quebec

and consequently to choose the most interesting indications for establishing simple two-dimensional diagrams| accessorily to verify the used terminology. So, for every series a two dimensional diagram is proposed allowing to follow the magmatic evolution during
the differentiation. Finally, the evolution of series of the North of Madagascar is also presented in the space defined by three principal axes.

On the multistage development of etch forms

to the evolution of etch forms, exploits magmatic, thermal, tectonic and sedimentary bedrock features at various scales, and of greater or lesser antiquity. It is more accurate and appropriate to view etchforms as complex and multistage features, some of which have

to shields, the type of the shelf crust exists, as illustrated by Central and Western Europe. The geosynclinal, tectogenetic and magmatic development conditioned by the drift in this shelf crust region is described in outline. The geotectonic events
are considered to be part of global processes. The drift stop at the end of the Palaeozoid epoch led to revolutionary changes in the system of global rotation, the major break in the evolution of life at the Permian-Triassic boundary being one of its sequels.

Metamorphose und Magmatismus in Venn-Stavelot-Massiv, Ardenen. (Metamorphosis and magmatism in the Venn-Stavelot-Massif, Ardennes)

A detailed study of granitic rocks round Zaria suggests that they are largely of magmatic origin. (EMS).

Evidence of tectonic influence on drainage evolution in an uplifting area: the case of northern Sila (Calabria, Italy)
The Sila Massif (Calabria, southern Italy) is a high-standing plateau with a rolling upland surface lying between 1000 and 1900 m. It is underlain by magmatic and metamorphic rocks thrusted over Mesozoic carbonate and terrigenous units. The Sila
the local tectonic constrains on the evolution of northern Sila drainage network in the context of the Calabrian Arc uplift. Results indicate that the drainage evolution has been strongly controlled primarily by local tectonics and secondarily by regional

Geochemical characteristics of the Eden Lake Complex : evidence for anorogenic magmatism in the Trans-Hudson Orogen

Orogenetic geosynclinal and magmatic cycles are controlled by worldwide lateral motions. To the end of herzynian cycle are in the area of Werdau-Hainichen trough and permocarboniferous basins in the northwestern part of CSSR eight or ten changes
of tectonic course. In times of dilation and while changes of tectonic direction intruded Hercynian magmatic bodies. (HL).

Magmatism and tectonics in Iceland. Special issue
The interaction of the Mid-Atlantic Ridge with the North Atlantic Mantle Plume has produced a magmatic plateau centered about Iceland. After a brief review of the tectonics of slow-spreading ridges, the AA. introduce the geological framework

metamorphism anatexis and magmatism in the district of the Ore Mountains-Lausitz. (HL).

According to the regional structural-tectonic and magmatic situation on the territory of the MPR there are three metallogenetic provinces. The mineralizations are essentially bound to the Caledonian, Hercynian and Mesozoic mineralization epochs. (HL).
