Appalachians in the Time Interval between the Grenville Orogeny and Variscan Collision America must be further reassessed according to the stages of movements..The Grenville Orogenic belt itself is far from being homogeneous and although . 1000 Ma orogenic ages are widespread, there are areas of much older metamorphic rocks within the Grenville Domain, and there is little juvenile Gr

Geodynamics of the Early Precambrian: Evidence for the Baltic Shield of the Baltic Shield is suggested. Ascent of superplumes was the leading mechanism of geodynamics. Archean granite-greenstone terranes and the early Paleoproterozoic cratons with mantle-derived magmatism occurred above extended superplumes heads. Between them zones of intense sagging movements took

Moreover, the fertile type is characterized by high Rb and low Sr. Also, direct relation between SiO. and Rb is obtained, while with Ba and Sr do not correlated well. The REE illustrate that the fertile granites possess high negative Eu value relative to the
