摘要：
A quartz porphyry dyke in the Kamioka Pb-Zn-Mo mining district shows large variations of Na, K, Ba and Sr concentrations with sodium negatively correlating to other three elements. These compositional changes are well explained by a model of liquid percolation through the rock, for which a mathematical formula was described by Haskin (1984). The liquid percolation brought about addition of K, Ba and Sr to the rock by compensating Na. Estimated composition for the liquid has K2O/Ba = 47 and Sr/Ba = 0.14. It is also indicated that D(Na) is in inverse proportion to the concentrations of K, Ba or Sr in the liquid.
