Security of supply of a number of raw materials is of concern for the European Union;
foremost among these are the rare earth elements (REE), which are used in a range of …

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 …

Lithology describes the geochemical, mineralogical, and physical properties of rocks. It
plays a key role in many processes at the Earth surface, especially the fluxes of matter to …

Twenty-three clastic metasediments from the Kongling high-grade terrain of the Yangtze
craton, South China were analyzed for major, trace and rare earth elements and Sm-Nd …

The composition of clastic sediments and rocks is controlled by a complex suite of
parameters operating during pedogenesis, erosion, transport, deposition, and burial. The …

Shales and mudrocks are enriched with diverse suites of major elements and trace metals
that reflect their depositional environment, provenance and diagenesis. Here we present …

Factors controlling the geochemistry of a clastic sedimentary rock can include:(1)
composition of source terrain,(2) chemical weathering,(3) hydraulic sorting,(4) …

Early Proterozoic (1.8-1.7 Ga) metasedimentary rocks in northern New Mexico and southern
Colorado, USA, can be divided into turbidite successions (commonly volcanogenic) …

An attempt is made to evaluate 6 tectonic setting discrimination diagrams (1 discriminant
function and 5 bivariate diagrams) frequently used by many researchers. For this purpose …

The major and trace element chemical composition of Precambrian and Paleozoic shales
and sandstones from the Iberian Range (Spain) has been investigated to determine the …
