Abstract

Introduction: The Ni-laterites were mostly derived from ultramafic rocks in opHiolite complexes during weathering in tropical climate. Lateritization processes result in leaching of some major elements (Si and Mg) from the source rocks and concentration of some others (Ni, Fe, Cr and Co) in the residual soils. The Ni-bearing laterites are divided into three major subgroups including oxides, silicates and clay types (Berger et al., 2011). Hematite and goethite are the main constituents of the oxides type, whereas garnierite is the main carrier for Ni in silicates type. In the clay laterite, saponite and smectite are the main Ni-carriers. The Bavanat region contains Ni-bearing laterites as discontinuous outcrops which have formed on opHiolite ultramafic rocks in the northeast Fars province. These ultramafics are remnants of Neo-Tethys oceanic lithospHere which have been emplaced on continental margin along the Zagros Suture Zone in the Late Cretaceous era (Rajabzadeh, 1998). These laterites have recently attracted some geologists to work on them (e. g. Khademi and Hasheminassab, 2010; Rasti and Rajabzadeh, 2017). The aim of this study is to determine the effects of pH, organic matter (OM) and weathering intensity on the geochemical and mineralogical characteristics of Ni-laterites in the Chesmeh Rostami area, Bavanat region...
