Apr 24, 2017· Intrusive rock is typically very hard and erodes slowly. This allows the surrounding rock to be worn away by wind and water, leaving only the harder rock in place. Heavy particles, such as gold, are likely to accumulate against the harder rock while the lighter materials are more easily moved away.
Jan 23, 2020· Rock density is very sensitive to the minerals that compose a particular rock type. Sedimentary rocks (and granite), which are rich in quartz and feldspar, tend to be less dense than volcanic rocks. And if you know your igneous petrology, you will see that the more mafic (rich in magnesium and iron) a rock is, the greater its density.
Rockchip sampling has returned gold to ppm in the conglomerate, ppm in the ashflow tuff, 435 ppb in silicified sandstone, 636 ppb in argillized basalt and 896 ppb in silicified limestone.
