Geochemical analyses by plasma spectroscopy

Geologiska Föreningen i Stockholm Förhandlingar, 1977
Abstract Microwave plasma (MWP) and inductively coupled plasma (ICP) have been used as excitation sources in spectroscopic analyses. The results show that MWP and ICP sources are excellent for spectroscopic determinations of a large number of major, minor and trace constituents in various geological materials.

Geochemical analyses of geological layers and groundwater flows

Environmental Geology, 2000
X-ray fluorescent spectroscope analysis easily finds ratios of geochemical elements in soil. Applying the method of ratio matching to measured ratios, the classification of geological layers, and the flow directions of groundwater can be determined.

Applications of error propagation analyses to geochemical calculation

Chinese Journal of Geochemistry, 1991
Two examples are given for comparing applications and limitations of four methods which can be used to deal with error propagation in geochemical calculations. The examples indicate that the Monte Carlo method can also be employed to evaluate the effect of covariance.
