Mineral Rich Lava Flows?
« on: 16/05/2006 04:29:01 »
Is it possible that a volcano could erupt spuing up gold ore and Iron and Vanadium instead of just cheap glass...?

Don't know of any that spew out pure gold, iron or vanadium.  Volcanic systems (especially silicic systems) are commonly enriched in these elements.  Since these elements (with the exception of iron) are usually found in the more volatile parts of the magma, they are commonly deposited by hydrothermal fluids in the volcanic system.

Subduction causes orogeny.

Many calderas are associated with important ore deposits, commonly lead-zinc-silver-gold, but also copper, molybdenum, tungsten, beryllium and uranium, and are associated with geothermal systems that originate in the volcano-plutonic transition zone.
