amical origins of seafloor spreading evolution were not available. For ancient times, a fundamental unknown is how seafloor spreading operates before the continents have reached their actual size. This study identifies the mechanisms of seafloor spreading evolution related to the growth of continents, making use of very recent and state-of-the-art 3D spherical dynamic models of convection in the mantle that produce plate-like tectonics. When continents grow, seafloor spreading becomes more active, the production of new seafloor increasing, along with its fluctuations. Because continental freeboard has remained close to its present-day value for two billion years, the results presented in this study reinforce the hypothesis that more than 90% of continental growth is restricted to the Hadean-Archean eons.


Crustal structure in southeastern Egypt: Symmetric thinning of the northern Red Sea rifted margins
Ahmed Hosny, Seismology Department, National Research Institute of Astronomy and Geophysics (NRIAG), Helwan, Cairo, Egypt, ahhosny2000@yahoo.com; and Andrew Nyblade, Department of Geosciences, Pennsylvania State University, University Park, Pennsylvania 16802, USA. Posted online 10 January 2014, http://dx.doi.org/10.1130/G34726.1.

From the abstract: Crustal structure in southeastern Egypt has been investigated to elucidate the nature of crustal thinning across the northern Red Sea. P-wave receiver function modeling for seven stations in southeastern Egypt yields typical Proterozoic crustal thicknesses of 35 to 38 km around Lake Aswan, and thinner crust (25 to 26 km) within 50 km of the Red Sea coast. Vp/Vs ratios are on average 1.78 and indicate an intermediate composition crust. These results, when combined with other estimates of crustal thickness in the region, reveal a symmetric pattern of crustal thickness benea
