THE main object of the research described in this monograph was to ascertain the amounts of many of the less common elements, including, certain members of the rare earth series, in the minerals and rocks of the East Indian Archipelago....
Earth, third planet from the Sun and the fifth largest planet in the solar system in terms of size and mass. Its single most outstanding feature is that its near-surface environments are the only places in the universe known to harbor life. Learn more ab

作者: S.,R.,Taylor,S.,M.,McLennan,R.,L.,Armstrong,J.,Tarney 摘要: The composition of the present-day upper crust, inferred from the uniformity of sedimentary rock r.e.e. (rare earth element) patterns, is close to that of granodiorite. A revised `andesite' model is used to obtain ...
Soil, the biologically active, porous medium that has developed in the uppermost layer of Earth’s crust. It is one of the principal substrata of life on Earth, serving as a reservoir of water and nutrients, as a medium for the filtration and breakdown o
DECIPHERING the geological evolution of the Earth's continental crust requires knowledge of its bulk composition and global variability, The main uncertainties are associated with the composition of the lower crust, Seismic measurements probe the elastic properties of the crust at depth, from which comp...
