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

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.

–rock interactions. Chemical weathering is clearly, at least, partly controlled by the input of magmatic CO2, either under hydrothermal (hot) or surficial (cold) weathering regimes. This study shows that the contribution of magmatic CO2 to chemical

to a distance of 1500 km from the studied sections, can be considered as the possible source of this layer. Nevertheless, tectono-magmatic evidence suggests that it may represent the witness of the activity of a calc-alkaline submarine volcanic arc located

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

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

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).
