“…Nevertheless, the model suffers from the large quantitative uncertainties underlying the diffusivity values and the partition coefficients. First elaborated for porphyrytype (Cu, Mo, W, Sn) deposits (Huber et al, 2012;Vigneresse, 2019), the model uses for simplicity a relative enrichment with respect to one component (Cl) of the MVP. It is the most common situation and best documented case of ore deposits related to granitic intrusions (Hedenquist et al, 2005).…”
