Abstract
Experimental, theoretical, and field investigations have demonstrated that chemical factors at the magmatic stage are important in determining Cu/Sn/W/Mo ratios in magmatic hydrothermal mineral deposits. However, physical characteristics probably work in concert with chemical controls to determine whether or not a mineral deposit will form and the size of the mineral deposit. An often neglected factor in the study of magmatic volatiles is the efficacy of transport of the volatile phase in the magma. In this communication, field evidence is presented that is consistent with a percolation cluster model for magmatic volatile-phase connectivity in a melt + crystal matrix. -Authors
