Many Lodes in the Comstock were in quartz veins, solidification by cooling of pre-historic molten silicon dioxide intrusions from volcanism. There are locations where the magma flooded into spaces, fissures, faults, fracture planes, known as sills (horizontal) and dikes (vertical). Some formations may be called quartz flooding.

	Lec 12 \| MIT 3.091 Introduction to Solid State Chemistry 1970s along came catalytic converters which we have to this day. And these are precious metal catalysts, platinum, palladium and rhodium. But when tetraethyl lead burns the carbon forms CO2, the hydrogen forms H2O and the lead forms lead dioxide. And lead dioxide is volatile. And it goes with the exhaust gases. And it will pass over the catalyst. And the catalyst's job is to break bonds. And so it breaks the lead-oxygen bond and reduces it to lead. And now the lead alloy is with the catalyst ...
