Visualization and interpretation of geochemical exploration data using GIS and machine learning methods
1. Introduction. Geochemical surveys have provided significant clues for mineral exploration, and many mineral deposits discoveries have been aided by the interpretation and visualization of geochemical survey data (Zuo et al., 2021).Various methods, including classic statistics (Hawkes and Webb, 1962), multivariate statistics (Reimann et al., 2008), geostatistics (Matheron, 1963), fractal ...
Current and emerging analytical techniques for geochemical and
Progress in both basic and applied geochemical studies highly depend on the progress of the analytical instrumentation in general. In recent times, there have been spectacular developments in different instrumental analytical techniques used for accurate determinations of elemental/isotopic abundances from per cent levels to pg/g levels in a variety of geological materials.

State-of-the-art analysis of geochemical data for mineral exploration
A critical component of geochemical analysis is the monitoring of all procedures that result in the analytical values. Quality control measures include the use of blanks, duplicates and standards to ensure that the results produced are fit for purpose. Two 'quality' parameters are commonly determined: precision, which measures the ...
Classification of geochemical data based on multivariate statistical
Identifying the data structure including trends and groups/clusters in geochemical problems is essential to discuss the origin of sources and processes from the observed variability of data. An increasing number and high dimensionality of recent geochemical data require efficient and accurate multivariate statistical analysis methods.
Geochemistry in earth sciences: a brief overview
Geochemistry is fundamentally based on the chemical analysis of natural materials (albeit for many of us mostly rocks and minerals). Geochemistry was born with our capacity to analyse and will grow for as long as we increase our capacity to analyse: i.e. widening the range of sample types and miniaturization of sample sizes, improved accuracy and precision and lowering of detection limits ...
Sample preparation for geochemical analysis: Strategies and
Sample preparation is a critical step in the geochemical analysis, and complete sample dissolution is a pre-requisite for obtaining accurate and precise data for geological materials in most studies. Sample matrix, analytes of interest, the analytical technique, and intended purpose play a major role in selecting the optimum sample preparation ...

Statistical analysis of soil geochemical data to identify pathfinders
Soil geochemical anomalies can be used to identify pathfinders in exploration for ore deposits. In this study, compositional data analysis is used with multivariate statistical methods to analyse soil geochemical data collected from the Coles Hill uranium deposit, Virginia, USA, to identify pathfinders associated with this deposit.
