ABSTRACT:
The article presents the results of
study of composition, structure and properties of three genetic types of
serpentinites from Ural: developed
by chromite-bearing ultrabasic rocks, by
metamorphic zones of carbonate rocks and within the zone of weathering of
ultrabasic rocks. The samples
were selected from deposits, located along the Main
Ural Fault - the Paleozoic subduction zone (named
GUR). Peculiarities of microstructure, chemical
composition and properties of serpentinites formed in different geological
conditions were investigated and their comparative study was held. Three groups
of serpentinites with oriented and non-oriented structure, which
formed by different protholites, were devided: mantle, lithosphere and crust.
