It is observed that the ratio of sand and clay in soil horizons developed on gabbro increased with the depth of the profile. The mineralogical studies carried out on gabbro indicate that the amount of quartz minerals in upper horizons of the soil increased, but that the amount of feldspar, pyroxene, amphibole and olivine minerals decreased. The soil horizons developed on gabbro, the amount of oxides such as Al2O3, Fe2O3 and MnO were increased and CaO, MgO, Na2O, K2O and P2O5 decreased with respect to host rock. It is observed that in this locality, the mobile trace elements such as Co, Sr and Cd were leached vertically, the semi mobile trace elements such as Cu, Ni, Ba and Zn, are leached away completely and the immobile trace elements such as Cr, Nb, Ce, and Zr were concentrated in soil profile. The data obtained from this locality is in the range of the North American Shale Composite (NASC).trinfo:eu-repo/semantics/closedAccessForest soilsgabbroacid soilsmineralogical contentmajor and trace element contentWeathering of Gabbroic Rocks in the Central Black Sea Area (Ordu) and Formation of Acid SoilsArticle14281912-s2.0-85044774122Q3WOS:000453165700010N/A
