introduction geological background ophiolites have played a major role in our understanding of earth’s processes ranging from seafloor spreading, melt evolution and magma transport in oceanic spreading centers, and hydrothermal alteration and mineralization of oceanic crust to collision tectonics, mountain building processes, and orogeny. they provide the essential structural, petrological, geo...

For nearly thirty years, Killarney Park has been one of Canada’s principal study sites for research into the ecological effects of acidification. Results of university and government-based research at Killarney contributed to major environmental improvements in North America including for example, the Clear Air Act Amendments. The area is now, once again, providing research opportunities unpara...

The Massif Central, like the southern part of the Massif Armoricain, belongs to the North Gondwana margin. The Massif Central consists of a stack of nappes resulting of six main tectonicmetamorphic events. The first one, D0, is coeval with an Early Late Silurian (ca 415 Ma) highpressure (or ultra high-pressure) metamorphism for which the associated structures are poorly documented. The Early De...
