The experimental modelling of formation of minerals during transformation of serpentine in presence of metallic iron and graphite at the mantle <i>P-T </i>parameters
This work contains the results of experiments carried out using a high pressure apparatus BARS at pressures 4 и 5,5 GPa and temperatures 1200° и 1350°С, respectively. The composition of the phases formed during the interaction of the decomposition products of serpentine with metallic iron and graphite was studied. It was shown that a change of the redox conditions of crystallization during the experiments results in the change of the ferocity of the newly formed silicate minerals
