Chemical differentiation of the Earth: the relationship between mantle, continental crust, and oceanic crust
The average chemical compositions of the continental crust and the oceanic crust (represented by MORB), normalized to primitive mantle values and plotted as functions of the apparent bulk partition coefficient of each element, form surprisingly simple, complementary concentration patterns. In the continental crust, the maximum concentrations are on the order of 50 to 100 times the primitive-man...
متن کاملModels of Vertical Movements of the Earth Crust Surface in the Area of Poland Derived from Leveling and Gnss Data
The known models of recent vertical movements of the Earth crust surface in the area of Poland were processed in the form of contour line map on the basis of the data of the first and second class geometric state levelling network. Second map done by Wyrzykowski (1985) was based on the results of measurements made in 1871-1882, 1926-1937, 1952-1956 and 1975-1977. The newest results of assignmen...

متن کاملSickness Assessment of Abbasid Caliphs and Their Causes of Death
Despite the peak of medical knowledge in the Abbasid period, the presence of famous medical families in the Abbasid court, translation and writing of medical works, attention to nutrition and health in the court of the Abbasid caliphs, the expectation of long life and quality was created for the Abbasid caliphs. However, all these possibilities were not used much by the caliphs, and if they had...
