The average thickness of the crust in eastern Antarctica is found to be about 35 km, as is typical of continents, whereas Marie Byrd Land with an average thickness of about 25 km cannot be regarded as truly continental. Love wave dispersion indicates that the thickness of the solid crust in...
The surface of the earth can be divided into the continental crust and the oceanic crust. The continental crust is made mostly of granite while the oceanic crust is made of basalt. The average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5...
thickness for various crustal types are summarized inFigure 4. Note that water layer thickness is included for oceanic structures. The averagePvelocity of the crust is 6.45 ± 0.21 km sec−1, the average continental crustal thickness is about 40 km and average oceanic crustal thickness is 12.6...
of the main density boundaries of the lithosphere, subtraction of these effects from the observed gravity field, and the subsequent conversion of the residual gravity anomalies first to the Moho depth and then to the total thickness of the Earth's crust and the thickness of its consolidated part...
Plot of averages of median Sr/Y values corresponding to the 2–6 wt.% MgO interval versus average arc crust thickness (ref. 35); (b). Plot of averages of median Sr/Y values corresponding to the 2–4 wt.% MgO interval versus arc thickness; (c). Plot of averages of median Sr/Y...
Here, using a statistical treatment of >23000 whole rock geochemical data, I show that average Sr/Y values and degree of maturation (MgO depletion at peak Sr/Y values) of 19 out of 22 Pliocene-Quaternary arcs correlate positively with arc thickness. This suggests that crustal thickness exerts...
Thickness of the sedimentary layer of structure of the Earth\"s crust in seas and oceans based on seismo-acoustic measurements. (In Russian; English abstract) : Udinsteb G. B., Yu P. Neprochnov and V. M. Kovylin, 1965. Oceanolog. Issled... None - 《deep sea research\\&\\oceanogr...
Crustal types representing properties in the crystalline crust are assigned according to basement age or tectonic setting. The classification of the latter loosely follows that of an updated map by Artemieva and Mooney (2001) (http://www.lithosphere.info). Statistical averages of crustal properties...

The great variety of rocks of which the crust of the earth is composed has been divided into three great groups in accordance with the manner in which they were formed. These groups are igneous, sedimentary and metamorphic. The igneous rocks are those which have solidified from a melted condit...
