Jan 22, 2016 · The ghost of continental crust long eroded away may exist in certain element ratios found in Archean rocks. Tang et al. used Ni/Co and Cr/Zn ratios as a proxy for the magnesium oxide that long ago weathered away in Earth's oldest rocks. This allowed a reconstruction of rock composition, which appears to be very different from that of the crust today. The shift to contemporary crust composition China Q345b Mild Steel Plate with High Strength - China Steel Plate, Carbon Steel Plate, Mild Steel Plate manufacturer / supplier in China, offering Q345b Mild Steel Plate with High Strength, 1.2mm Thickness 201 Stainless Steel Sheet Plate, 2b Finished 0.5mm 0.8mm Thickness AISI 201 Stainless Steel Plate and so on.
