Eh and pH in Geochemical Exploration

Geochemical dispersion of metals under various environmental conditions is discussed within the frame\ work of Eh (oxidation potential) and pH (acidity). In general, two aspects are considered - (1) the oxidation of certain primary sulphides in the outcrop or sub-outcrop environment, and (2) the movement of metals in different dispersion media. Practical applications of each are illustrated by means of exploration case histories representing environmental conditions in the Canadian Shield, the southwestern United States and the Caribbean.
