Modeling Sedimentary Deposits on the Continental Margin
A first objective is to investigate the fabric (pattern) of seabed stratification on continental margins at small time and space scales (1 cm-50 cm depth into the seabed; 1 hr-3 yrs sedimentary record). To this end, we are testing the hypothesis that on muddy shelves such as the northern California shelf, Holocene event stratigraphy consists of the deposits of high-concentration storm regimes a...
متن کاملTectonic 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...
متن کاملGeochemistry 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...
متن کاملRift migration explains continental margin asymmetry and crustal hyper-extension
When continents break apart, continental crust and lithosphere are thinned until break-up is achieved and an oceanic basin is formed. The most remarkable and least understood structures associated with this process are up to 200 km wide areas of hyper-extended continental crust, which are partitioned between conjugate margins with pronounced asymmetry. Here we show, using high-resolution thermo...
