Webthe extension value estimated from preservation of the volume of the crust is about 12 km [Bois, 1993]. As it has been shown that the northern segment was affected by two distinct periods of extension, the extension value resulting from the West European rift episode only is probably about 12 km. Thus the extension rate deduced WebSeven alkali basalt centers in the southern Canadian Cordillera INTRODUCTION contain mantle xenolith suites that comprise spinel Cr-diopside Spinel peridotite xenoliths occur in many alkali basalt peridotites, spinel augite-bearing wehrlites and orthopyroxene-poor centers of the Canadian Cordillera, a Phanerozoic conlherzolites, and minor pyroxenites. Web15 mei 2002 · When extension is characterized by lower velocities, the lithosphere reacts differently. The results of one representative test (total extension rate of ∼6 mm/yr) have been selected to illustrate this. The lithosphere is stretched relatively slowly in this case for a period of more than 100 Myr. irr00/new/default.asp

Web10 nov. 1991 · Abstract. A simplified model of continental extension including lower crustal flow is developed. The model employs the thin sheet approximation in estimating lithospheric yield strength and gravitational buoyancy forces arising from lateral variations in crustal thickness and temperature. Web[2] Lithospheric modification during continental rifting is an axiomatic consequence of plate tectonic processes. The processes whereby the continental crust is modified by magmatism during the progressive evolution from continental rifting to seafloor spreading, are however poorly constrained.
