Variable Sr Diffusion and Implications for Rb–Sr Biotite Geochronology

Journal of Metamorphic Geology, EarlyView.
ABSTRACT The rubidium–strontium (Rb–Sr) system has a long pedigree as a geochronological tool that relies on the application of an isochron approach. In particular, biotite contains strongly radiogenic Rb–Sr isotopes, and thus can yield meaningful crystallisation or cooling ages via this approach. However, the response of the Rb–Sr system in biotite to

The types of the earth's crust

Journal of Geodynamics, 1984
Abstract For the comprehensive mapping of the deep structure of the Earth's crust a determination of the general types of the crust based on its most essential structural parameters is attempted. Three parameters are considered as most informative, and are accepted as basic for this purpose: thickness of the Earth's curst, thickness of the ...

Structure of the Earth's Crust in the Continents

Science, 1950
In 1910 A. Mohorovicic published the first paper in which arrival times of elastic waves from a near-by earthquake were used to calculate the velocity of earthquake waves in the earth's crust, He found for longitudinal waves a velocity of 5.4 km/ sec in the upper 50 km and a velocity of about 7.8 km/sec below that.

The Earth’s Crust

1970
The part of the earth on which we live is the weathered crust of the lithosphere, the surface of our planet. Beneath the lithosphere are the mantle and the core of the earth. The crust is the exposed surface of the lithosphere that has been modified in various ways by climate and by the vegetation that forms a cover where the climate is favorable to ...
