Sulfur isotopes of some central African sulfide deposits

Sulfur isotope ratios provide clues for separating the diverse effects of biogenic sulfur deposition, metamorphism and granitization, and igneous processes in various types of rock and ore deposits. It is concluded that metamorphic processes related to the rise of mantled domes during the Lufilian orogeny (Precambrian) have been important agents in the formation of the Rhodesian copper belt.
