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.

A Streamlined Workflow From Experimental Analyses to Dynamic Geochemical Modelling

SPE Europec featured at 82nd EAGE Conference and Exhibition, 2021
Abstract Dynamic-geochemical model is a powerful instrument to evaluate the geochemical effects on CO2storage capacity, injectivity and long-term containment. The study objective is to apply an integrated multi-step workflow to a carbon capture and storage (CCS) candidate field (offshore), namely hereinafter H field.

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.

Statistical analyses of geochemical variables in soils of Ireland

Geoderma, 2008
Abstract Geochemical variables in soils are affected by multiple factors, and different variables have different responses to these factors, causing complicated multivariate relationships between them. In this study, the relationships between a total of 45 geochemical variables in soils and in particular mineral soils of Ireland were investigated ...
