Petrochemistry, trace elements of the Denezhkin Kamen’ rocks (the platinum-bearing belt of the Urals)

The 170 samples from 7910 meters profile long of the massif of Denezhkin Kamen’ (the Platinum-Bearing Belt of the Urals) were selected for determination of trace elements concentration by FS HR ICP-MS Elenent2. Results of this analysis is identification of reflecting process of plastic deformation, tectonic and chemical mixture of two solid initial units - the dunit- pyroxenic and olivin-gabbro. The revealed geochemical gradients correlate with a block stratigraphy, and the absolute majority of trace elements concentrations finds an obvious tendency to accumulation in the bottom 3-km zone of the section put by sharply expressed porphyroclastic structure rocks.
