    Previous studies of deforestation have focused on agriculture, population and migration, timber exploitation, macroeconomic policies and geographic factors to explain the variability of deforestation rates among countries. This study tests the hypothesis that countries with a high proportion of petroleum or nonpetroleum mineral exports in total exports experience a relatively low deforestation

    Effects of mineral distribution at mesoscopic scale on

    [1] The mesostructure (millimeter to micrometer scale) of clayrich sedimentary rocks is generally characterized by a connected finegrained clay matrix embedding coarser nonclay minerals. We use the CallovoOxfordian clayrich rock formation (France) to illustrate how mesostructure influences solute transfer in clayrich rocks at larger scales.

    Mineral species are differentiated solely by mineral composition, whereas mineral varieties are differentiated solely by mineral structure. e. A mineral species, which is a single type of mineral that varies due to the impurities that it contains, is a subsection within a mineral variety, which is a collection of mineral specimens that exhibit similar internal structures and chemical compositions.
