Using the ideas of similarity of spatial parameters of structures and treatment of materials on spatial characteristics of crystalline cells and monocrystals in comparison with conditional potentials of ionization, we obtained the equation of regression (R2 = 0.96): Y = 1100.7 (K’ pm*) 0.099 (kdzh/g), where K’ = h/S – dimen-sionless magnitude characterizing vertical and horizontal sizes of a structure, p = 2.154…; m* = ± 0,1,2,… .Taking into account the sizes of structures of micro- to macro-levels, we used Y parameter for characteristics of different-scale tectonic and tectonomagmatic systems and called it a conditional geodynamic potential.
Calculations of the potential are given for a wide spectrum of objects – from minerals to island arcs, rifts, and seismic centers. Values of the geodynamic potential of structures are discrete and form the quantized energetic zones: Ys = Y0ds, where s – a number of a zone and d = 1.0789… .
As tectonomagmatic systems develop with decreasing rate of propagation of geodynamic field (deformation rate), the geodynamic potential of structures increases and radiation of seismic energy decreases. This event results in more intensive force interaction in the “melt-structure” system and, consequently, in increase of the relative differentiation index of the composition of magmatism products. In the composition of accompanying mineralization, the role of parageneses of oxyphylic elements, having higher energetic relations with oxygen, increases.
The geodynamic potential and P-T parameters of formation of mineral associations are in direct dependence. Increase of a share of magmatic matter with enhanced alkalinity correlates with increase of the geodynamic potential of structures, pressure, and temperature in the process of generation and differentiation of magmas.
