Zusammenfassung

Fluid inclusion data from Aznalcóllar and Los Frailes stockworks indicate that hydrothermal fluids changed continuously in temperature and salinity, both in time and space. Th values change from 140 to 380 oC and salinity from 0.4 to 12.4 NaC/ eq. The highest values for both parameters have being found for central stockworks and later fluids. Statistic population analysis of fluid inclusion data points to three stages of hydrothermal activity, at low <200 ºC intermediate (200-300 °C) and high temperatures (300-400 ºC). Salinity values show similar variation trend with higher values for the last hydrothermal stage.
