Regularities of influence of a single-phase SP oxidation and a subsequent decomposition of synthetic titanomagnetites TM of a different original composition Fe3-x TixO4 where x = 0.2, 0.4 and 0.6 upon the change of their hysteresis parameters and on properties of the resultant chemical remanent magnetization CRM were determined as a result of the laboratory researches. Calculations were made of the changes of magnetization of the igneous rocks similar to the investigated TM of a composition with x = 0.4 taking into account SP changes of the primary titanomagnetite at a high partial pressure of oxygen. The influence of CRM on safety of the primary thermoremanent magnetization at different stages of the SP oxidation of TM and decomposition of the cation-deficient TM was assessed. The results which were obtained may be used for interpretation of changes in the magnetic properties of the submicron grains of TM in the course of their thermal transformation on the earth surface.
