Cǒcte d'Ivoire-Ghana margin: seismic imaging of passive rifted crust adjacent to a transform continental margin

Evolution of the Kap Edvard Holm Complex : a Mafic Intrusion at a Rifted Continental Margin

The Kap Edvard Holm Layered Series forms part of the East Greenland Tertiary Province, and was emplaced at shallow crustal level (at depths corresponding to a pressure of 1-2 kbar) during continental break-up. It consists of two suites: a gabbro suite comprising olivine and oxide gabbros, leucocratic olivine gabbros and anorthosites, and a suite of wehrlites that formed from the intrusion of th...

A Mesoarchean Rifted Continental Margin in the Wyoming Province: Evidence for Supercontinent Breakup

Tectonic inheritance at a continental margin

GSA Today: v. 16, no. 2, doi: 10.1130/1052-5173(2006)016<4:TIAACM>2.0.CO;2 INTRODUCTION Forty years ago, the eastern margin of North America inspired Tuzo Wilson (1966) to ask, “Did the Atlantic close and then re-open?” The Wilson cycle of closing and opening of ocean basins incorporates the cyclic assembly and breakup of supercontinents. Alternate processes of extension and compression of cont...

Seismic Imaging of Microblocks and Weak Zones in the Crust Beneath the Southeastern Margin of the Tibetan Plateau

Geochemistry and Thermobarometry of Bazman volcanic rocks, An example of active continental margin volcano

  Bazman volcano is located in the Makran-Chaghi magmatic arc in southeastern Iran. Many studies have been done on this volcano, especially of petrology such as: Biabangard and Mollazadehbarvati, 2017; Berberian and Berberian, 1982; Mohammadi, 2005; Sahandi et al., 2010; Schmidt and Dabiri, 2019; Firoozkoohi, et al., 2017; Ghodsi et al., 2006; Glamghash et al., 2015; Karimpour et al., 2012; St...
