The Earth as a planetary system has experienced significant change since its formation c.
4.54 Gyr ago. Some of these changes have been gradual, such as secular cooling of the …

A survey is given of the dimensions and composition of the present continental crust. The
abundances of immobile elements in sedimentary rocks are used to establish upper crustal …

Ultrahigh temperature (UHT) metamorphism is the most thermally extreme form of regional
crustal metamorphism, with temperatures exceeding 900° C. UHT crustal metamorphism is …

The Treatise on Geochemistry is the first work providing a comprehensive, integrated
summary of the present state of geochemistry. It deals with all the major subjects in the field …

Geophysical, petrological, and geochemical data provide important clues about the
composition of the deep continental crust. On the basis of seismic refraction data, we divide …

We report abundances of sixty-three major, trace, and rare earth elements in the upper crust
in five tectonic units (the interior and southern margin of the North China craton, the North …

Many granites result from anatexis of common crustal rock types and the segregation,
aggregation, ascent and emplacement of the resultant magma. What then is the connection …

To this day, there is a great amount of controversy about where, when and how the so-called
supercontinents--Pangea, Godwana, Rodinia, and Columbia--were made and broken …

Bulk continental crustal composition results from the net mass exchange between crust and
mantle. Crustal addition is mainly by the rise of mantle-derived melts into and through the …

The thermal structure of a generic subduction zone is investigated to elucidate the source
region of subduction zone volcanics. The steady state thermal field is evaluated for a model …
