Architecture of the distal Piedmont-Ligurian rifted margin in NW-Italy: hints for a flip of the rift system polarity†

DOI: 10.1002/2017tc004561
Abstract: The Alpine Tethys rifted margins were generated by a Mesozoic polyphase magma-poor rifting leading to the opening of the Piedmont-Ligurian “Ocean”. This latter developed through different phases of rifting that terminated with the exhumation of… read more here.

DOI: 10.1007/s00445-020-01391-7
Abstract: The composition of gas emitted from a volcano producing basalt magma can vary during an eruption and according to the volcano-tectonic setting of the degassing vents. Post-eruptive filter-pack gas samples from the 2014–2015 Holuhraun crater… read more here.

DOI: 10.1016/j.chemgeo.2020.120019
Abstract: Abstract Mesozoic diamondiferous lamproite pipes occur along the Kapamba River within the Luangwa Valley of eastern Zambia, which is a ca. 300–200 Ma old Karoo-age precursor branch to the East African Rift System. The Luangwa Rift… read more here.

Aspects of the Archean-Proterozoic transition: How the great Huronian Glacial Event was initiated by rift-related uplift and terminated at the rift-drift transition during break-up of Lauroscandia

DOI: 10.1016/j.earscirev.2018.12.013
Abstract: Abstract The Archean-Proterozoic transition was among the most important in geological history for it includes evidence of establishment of ‘modern-style’ plate tectonics, unprecedented paleoclimatic upheavals, and oxygenation of the atmosphere. The early Paleoproterozoic sedimentary record… read more here.

DOI: 10.1016/j.epsl.2017.11.040
Abstract: Abstract The Baikal Rift Zone (BRZ) is an active intracontinental rift zone with almost no rift-related magmatism along the rift axis. Most magmatism is observed outside the rift center, and e.g. the major Vitim volcanic… read more here.

DOI: 10.1016/j.epsl.2018.01.037
Abstract: Abstract In continental rifts structural heterogeneities, such as pre-existing faults and foliations, are thought to influence shallow crustal processes, particularly the formation of rift faults, magma reservoirs and surface volcanism. We focus on the Corbetti… read more here.

DOI: 10.1016/j.epsl.2018.02.027
Abstract: Abstract Magma plays a vital role in the break-up of continental lithosphere. However, significant uncertainty remains about how magma-crust interactions and melt evolution vary during the development of a rift system. Ethiopia captures the transition… read more here.
