A new method to evaluate the role of fractional crystallization is presented in this paper, based on the Rayleigh Law for trace elements. A major element "j" (x) and a trace element "i" (y) of a set ...

A new variation diagram has been devised in which the ratio $\frac{Total O not combined in OH^{-}}{Si^{+4}+ (A1^{+3} in 4-co-ordination)}X10$ is plotted as abscissa. This ratio, here called the ...

The continental crust is central to the biological and geological history of Earth. However, crustal heterogeneity has prevented a thorough geochemical comparison of its primary igneous building ...

Researchers at the US’s Idaho National Laboratory have taken a water treatment technology and adapted it for selectively separating rare earth elements and transition metals. This chemical process, ...

The charge of a single electron, e, is defined as the basic unit of electric charge. Because electrons - the subatomic particles that carry electricity - are elementary particles and cannot be split, ...

It's not uncommon in the scientific world for a process to have many unique applications. Researchers have taken a water treatment technology and adapted it for another environmentally important ...
