17 Σεπ 2020 · We present an updated oceanic crustal age grid and a set of complementary grids including spreading rate, asymmetry, direction, and obliquity. Our data set is based on a selected set of magnetic anomaly identifications and the plate tectonic model of Müller et al. (2019, 10.1029/2018TC005462).
3 Απρ 2008 · Here we present a new set of grids, including a complete grid of oceanic crustal ages without gaps, based on a revised set of global plate rotations (auxiliary material Tables S1a–S1f), as well as gridded seafloor spreading half rates and spreading asymmetry.
Seafloor Spreading. Description. This data table provides spreading rates for divergent boundaries (spreading centers) in the Pacific, Atlantic, and Indian oceans. The rates differ between the 3 spreading centers and along their respective boundaries.
older than previous studies. We also present data sets showing various seafloor spreading parameters such as spreading rate, asymmetry, direction, and obliquity. Slow and intermediate seafloor spreading rates produce the most stable spreading behavior in terms of asymmtery and obliquity. Our data sets and
2 Οκτ 2020 · The results from our modeling show that the initial seafloor spreading began approximately 16 million years ago, with spreading rates varying from 12.29 to 20.12 mm/yr (average = 15.75...
25 Σεπ 2008 · The authors present four companion digital models of the age, age uncertainty, spreading rates and spreading asymmetries of the world's ocean basins as geographic and Mercator grids with 2 minute resolution.
Spreading rate is the rate at which an ocean basin widens due to seafloor spreading. (The rate at which new oceanic lithosphere is added to each tectonic plate on either side of a mid-ocean ridge is the spreading half-rate and is equal to half of the spreading rate).
