Ga/Ge and Ga/Zn atomic ratios are interpreted as the chemical result of hydrolysis reactions of silicate rocks. Under simplifying assumptions diagrams of Ga/Ge and Ga/Zn vs. pH have been calculated for various temperatures. These graphs allow to read best-fitting sets of parameters (T, pH, ΣS) for each ore subprovince in areas like the Calcareous Alps. For Gorno/Italy, Rauschberg/Germany and Bleiberg-Kreuth/Austria sets of parameters for the last equilibration of the ore fluid have been derived. These data indicate that hydrothermal solutions entered the depositional environment.

Ga/Ge and Ga/Zn-Atomverhältnisse werden als das Ergebnis der Hydrolyse von Silikaten gedeutet. Unter vereinfachenden Annahmen werden Ga/Ge vs. pH- und Ga/Zn vs. pH-Diagramme für verschiedene Temperaturen berechnet. Mit ihrer Hilfe lassen sich wahrscheinlichste Sätze von Parametern (T, pH, ΣS) aus den analytisch ermittelten Ga/Ge and Ga/Zn-Verhältnissen in Sphaleriten verschiedener Regionen der Kalkalpen ableiten. Die Ergebnisse für Gorno (Italien), Rauschberg (Deutschland) und Bleiberg-Kreuth (Österreich) zeigen auf, daß die Erzlösungen das letzte Mal bei T > 200°C (Gorno, Rauschberg) und T > 50°C (Bleiberg-Kreuth) mit Silikaten im Gleichgewicht standen.
