Their indicator role during serpentinization process is considered on the basis of the regularities of the distribution of the iron family elements in the main types and varieties of serpentinites. Despite the fact that these elements are very close according to geochemical features, their behavior in this process is sharply different. While titanium and vanadium gravitate toward magnesian rock-forming minerals then cobalt and nickel give preference to more ferrous varieties. From this position behavior of chromium and manganese are different. If absolute stability is considered in manganese behavior then chromium in the initial stages of serpentinization occurs mainly as intrinsic mineral-chromite. Further it enters isomorphically into the composition of rock-forming minerals replacing aluminum and ferric iron.
