nt flows with time resulting in a complex basin fill. The seafloor was dominated by very coarse-grained sediments -- some as large as houses -- that were sourced from steep slopes, a multitude of rivers, and small deltas. In comparison with other submarine rift-margin-basins globally, Strachan and colleagues found little commonality in vertical sedimentary trends -- a testament to the wide variety of sub-environments and flow processes, and their response to coeval tectonic and paleoclimatic events


The continental record and the generation of continental crust
P.A. Cawood et al., Dept. of Earth Sciences, University of St. Andrews, North Street, St. Andrews KY16 9AL, UK. Posted online 31 October 2012; http://dx.doi.org/10.1130/B30722.1.

Continental crust is the archive of Earth's history. It is characterized by peaks of crystallization ages are that linked to the timing of the assembly of supercontinents. These peaks of ages reflect a tectonic bias because igneous and metamorphic rocks generated in late stage convergence and collision zones are most likely to be preserved, rather than fundamental pulses of magmatic activity. New analysis of the isotope ratios in the mineral zircon, which occurs as fragments in sedimentary rocks, suggests that at least ~60%-70% of the present volume of the continental crust had been generated by three billion years ago. These data show that growth of continental crust was continuous rather than episodic, and there was a marked decrease in the rate of crustal growth at about three billion years ago that may have been linked to the onset of significant crustal recycling, probably though subduction at convergent plate margins. The 60%-70% of the present volume of the continental crust estimated to have been present three billion years ago, contrasts markedly with less than 10% of crust of that age apparently still preserved.
