Birth and decay of an intracontinental magmatic swell: early Cretaceous tectonics of southern Israel
Article Abstract:
A study was conducted on the intracontinental magmatic swell that was formed during the Early Creatceous in Israel to examine its formation, growth, decay and geodynamic mechanism. Results showed that most of the swell's crest remained elevated for 10 Myr after the initial uplift indicating that the permanent buoyancy effect of intrusions was the major cause for uplifting. Transient effects may have also took place, but have a minimal influence to the local uplifting.

40Ar/39Ar evidence for middle proterozoic (1300-1500 Ma) slow cooling of the southern Black Hills, South Dakota, midcontinent, North America: implications for early proterozoic P-T evolution and posttectonic magmatism
Article Abstract:
The 40Ar/39Ar evidence for middle proterozoic slow cooling of the southern Black Hills, SD, was examined to determine its implications for early proterozoic P-T evolution and posttectonic magmatism. The research utilized proterozoic mica dates from metasedimentary rocks. Results revealed that uplift and crustal thinning before the Harney Peak Granite intrusion was due to differential thinning of the subcrustal lithosphere beneath the Black Hills.

Slab breakoff: a model for syncollisional magmatism and tectonics in the Alps
Article Abstract:
A quantitative thermo-mechanical modeling strategy proved useful in elucidating the nature of tertiary evolution of the European Alps mountain ranges. This slab breakoff hypothesis model provides plausible explanations of the Tertiary magmatism, uplift and exhumation of continental rocks displaced to mantle depths.
