  abstract = {{A}rtificialized soils encompass a large diversity depending both on the environmental conditions and the history of land uses. {T}heir study requires to develop an approach to compare and classify them. {V}ibrational spectroscopies are used in soil science to collect rapid and cost-effective molecular information about inorganic and organic soil constituents [1]. {C}oupled with chemometrics approaches (e.g. [2]), they can be used to estimate some properties and/or to classify soils [3]. {T}his study aims at exploring the potential of mid-infrared spectroscopy (i) to differentiate soils depending on past land uses, (ii) to propose a soil typology and (iii) to define markers of human activities. {A} set of 150 surface soil samples from the {N}orth-{E}ast of {F}rance was selected, including agricultural and forest soils developed on various bedrocks and soils impacted by iron and glass industry, mining, charcoal production or old human settlements. {M}id-infrared analyses were run in diffuse reflectance mode. {A}n exploratory study was performed on the preprocessed spectra using ascending hierarchical classification and principal component analysis. {S}tudied soils can be distinguished based on their mineralogical composition (carbonates, clays) and, to a lesser extent, on the presence of organic compounds ({F}ig1). {H}owever, changes related to old settlements, mining or charcoal production were more difficult to discriminate. {T}his could be improved by coupling several spectroscopic analyses providing complementary information on the samples.},
