Temperature-dependent resistivity variations in serpentinites from the Bazhenov deposit (the Urals)

The paper considers the effect of high temperatures on the behavior of elec trical resistivity of dunite and harzburgite serpentinites from the Bazheno v chrysotile-asbestos deposit. This behavior was found out to depend on the source-rock composition and genesis of serpentinites. Namely, the temperat ure dependence of resistivity, Ig R = f(T) is controlled by rock mineralogy (presence or absence of brucite) determined by the primary composition bf the ultramafics and the physicochemical conditions of serpentinization. The obtanied results have been correlated with data of thermal, mineralogical, chemical, and other analyses.
