    Interpretacja chemizmu wód kopalnianych metodami analizy danych złożonych
    (2007) Labus, Krzysztof
    The paper presents the principles bases of Compositional Data Analysis (CDA). This statistical method enables interpreting the data, being proportions of some whole. The implementation of this method was presented on an example of mine waters from the Chwałowice coal mine (Silesia). The visualization by means of ternary diagrams was helpful for interpreting the results. CDA was especially useful in identifying the following hydrochemical processes to occur in the mine waters' environment: ion exchange, halite dissolution, sulfates reduction, barite precipitation, and desorption of iodine from the aquifer material.
