Annotation

The Okhansk meteorite belong to group of olivine-bronzite H-chondrites [1-3]. It is intensively brecciated and is represented by a disorderly mixture of silicate chondrules, their breaks and their fine-grained matrix enclosed by silicate minerals, interstitial silicate glass and ore minerals (kamacite, troilite). The chondrules fill about one third of the meteorite volume. Their size is usually 0.2-0.9 mm. They consist of olivine, bronzite, diopside, plagioclase. Often they contain silicate glass. The chondrules and Okhansk meteorite substance underwent secondary low-temperature (hydrothermal) transformations. It can be assumed that the substance of future Okhansk meteorite was located in near-surface zone of parent body, in which the processes of internal differentiation of its substance took place, and in its near-surface part they were expressed in development of hydrothermal processes with addition of H2O, CO2, CO, Si, Ca, Mg, K, Na and hydrocarbons. These processes led to the hydrocarbonization, carbonatization, silicification, serpentinization, chloritization.
