How Gold Ore is Formed · Genesis
Among such rocks are granite, aplite, gneiss, eurite, quartz-trachyte, syenite, andesite, basalt, diorite, gabbro, diabase, schists, porphyry and slate. These deposits seldom pay to work and in that case can hardly be called gold ores. J. E. Spurr writes—"Native gold has been found in both basic and acid rocks.
