ДО УМОВ ФОРМУВАННЯ АСОЦІАЦІЙ МІНЕРАЛІВ І ВЕРТИКАЛЬНОЇ ЗОНАЛЬНОСТІ НА КВАСІВСЬКОМУ РУДНОМУ ПОЛІ (ЗАКАРПАТТЯ)

Two types of zoning of local value are distinquished in the vertical section of mine
field. The conditions of tuff formation are marked by wide temperature limits (from
>1400°C to 800-900°C) and different magma saturation by volatiles components. Regime
of phase changes in magmatic inclusions during heating essentially depends from ratio of
thermovolumetric expansion (contration) of magmatic melt in inclusions and quartz
coefficients (taking account α-β-transition). Hydrothermal process is characterized by decrease of temperature and general concentration of solutions (accordingly: 300-100°C, 12,3-2,0 vol.%). Francolite (carbonat-apatite) is a mineral of the finishing stage of this process.
