"Apparues au XIXe siècle, les fractales furent considérées comme des curiosités mathématiques jusqu'au milieu du XXe siècle. Pourtant, nous pouvons voir des fractales partout... Cette géométrie est une extension de la géométrie classique qui peut faire des modèles précis de structures physiques comme des fougères ou des galaxies. La géométrie fractale est une nouvelle langue. Une fois que vous la parlez, vous pouvez décrire la forme d'un nuage aussi précisément qu'un architecte peut décrire une maison. Ce petit ouvrage retrace l'évolution historique de cette discipline mathématique, explore ses pouvoirs descriptifs dans la [sic] monde naturel, puis se penche sur les applications et les implications qu'elle a induites."

Fractals and Multifractals in the Geosciences details the application of a wide range of multifractal methods, including many novel ones developed by the author, along with the assessment of uncertainty in sample classification and stability of spatial patterns. This book also provides criteria for selection of the most effective combination of data pre-processing and multifractal modeling to extract desired features or signals in the data. The book specifically aims to introduce, apply, and test novel multifractal models that account directly for changes in relationships between variables, as well as the effects of distance between samples and the source of anomalous metal contents in geoscience samples. Linked to this will be assessment of the effects of different pre-processing of data prior to application of the models and quantification/model uncertainty in geochemical anomaly maps, associated with sample classification and spatial interpolation. Gaussian simulations such as Sequential Gaussian Simulation and Monte Carlo Simulation will be applied to the new multifractal models developed and a suite of existing models, including (simulated) concentration-area, spectrum-area, singularity and other models.Fractals and Multifractals in the Geosciences will be invaluable for mathematical geoscientists, geostatisticians, exploration, applied, urban and environmental geochemists, computational geoscientists, data scientists, and GIS professionals who need to better understand fractal geometry, along with its theory and applications in geochemical anomaly classification to generate maps that are helpful for decision-making for follow-up sampling and explorations.
