Geochemical Characteristics of Archaean Ultramafic and Mafic Volcanic Rocks: Implications for Mantlat least for the upper mantle, was completed before 3.8 Ga ago. Moreover, a significant degree of mantle-crust and/or intra-mantle differentiation in the pre-Archaean (>3.8 Ga) is indicated by Nd and Sr isotopic data..Chondritic ratios for refractory lithophile elements (e.g. Al, Ti, Zr, Y, REE) are

Archaean Sedimentary Rocks and Their Relation to the Composition of the Archaean Continental Crust,thought to reflect the composition of the exposed upper continental crust. In contrast, Archaean sedimentary rocks display highly variable trace element abundances, but on average have lower levels of incompatible elements (Th, LREE), lower La/Yb ratios and lack the Eu depletion characteristic of po

Origin of Archaean Charnockites from Southern India,a continuous series exists from mafic to tonalite-trondhjemite end members. With the exception of K.O, major element distributions reflect the original igneous parentage of the rocks. Rb, Cs, Th, U, and Pb are depleted in charnockites although the degree of depletion does not correlate well with inf

Radiometric Ages (Rb-Sr, Sm-Nd, U-Pb) and REE Geochemistry of Archaean Granulite Gneisses from East and trace element geochemistry. A consistent age of about 2.5 Ga has been obtained by the Rb-Sr and Sm-Nd whole-rock isochron methods, in agreement with the zircon U-Pb data (Pidgeon 1980; Liu et al. 1984). Geochemical arguments from initial isotopic ratios (I. and I.) and elemental distribution pa
