Late Paleozoic rifting in northern Pakistan
Article Abstract:
Late Paleozoic rifting in northern Pakistan was investigated using stratigraphic, structural, geochemical and radiometric analyses of samples and sites in the area. Derived clasts from Jafar Kandao is indicative of extensional tectonics that took place in the Early Carboniferous. The area underwent uplift during the early Permian and Carboniferous periods accompanied by magmatism. The tectonic history in the north parallels that of central Pakistan indicating continuity of the two areas before the Neo-Tethys opened up.

Contrasting styles of rifting: models and examples from the eastern Canadian margin
Article Abstract:
A study of the wide range of crustal thinning patterns across rifted passive margins reveal that the patterns can be produced by varying the geotherm, the lithospheric composition and the strain rate. Locus of extension migrates when the thinned area cools and hardens during extension. In such cases, along one edge of the thinned area rupture takes places. The locus of extension migrates from the center of the rift to the edges when it is cool, and results in an asymmetric breakup.

Early Paleozoic orogenic collapse, tectonic stability, and late Paleozoic continental rifting revealed through thermochronology of K-feldspars, southern Norway
Article Abstract:
The middle to late Paleozoic thermal history of the southern Norwegian crust was studied using K-feldspar thermochronology and geologic constraints. It was observed that the late Paleozoic period was characterized by a cooling phase. This may be attributed to decrease in the base level and the rise in the rate of erosional denudation around the margin of southern Norway due to rifting.
