Course objectives
The course is focused on the acquisition of theoretical and practical background of geochemical data processing (mineral and rock analyses) using mathematical and statistical methods and graphic presentation using Microsoft Excel GCDkit.
Learning outcomes
Student will be able to use basic mathematical and statistical methods on geochemical data (mineral and rock analyses) using Microsoft Excel a GCDkit and will be able to interpret them after completing the course. Student will be able to process the data graphically in the given programs and interpret them.
Syllabus
  • 1. Geological data, types of geological data. Major and trace elements in rocks and minerals and their use in geochemical interpretations. Graphical presentation, types of graphs used in geosciences, Normalisation of geochemical data. Calculations of major geochemical parameters in normalised graphs 2. Geochemistry of magmatic rocks; Classification diagrams of magmatic (extrusive and plutonic) rocks. 3. Description of univariate data. Random sampling. Distribution of data in the population - frequency distribution. Graphing the frequency distribution; Graphical presentation of univariate data 4. Basic types of frequency distributions in geology. Distributions - normal, log-normal, binomial, special types (t-, F, chi square distributions). Examples of geological phenomena and their frequency distributions. 5. Basic statistical parameters Median, quantiles, mode, range, arithmetic mean, geometrical mean,….and their use in geology. 6. Testing statistical hypotheses Basic terms and testing procedures. The main tests in geology. 7. Statistical description of relations between variables. Correlation analysis. Regression analysis and their use in geology and substitution in minerals, Graphical presentation of substitution in minerals.
