Stratabound gold deposits in Archean banded iron …

Experimental evidence on gold solubility and data from active fumarolicstage geothermal areas support the view that thermal brines are capable of transporting significant quantities of gold and other metals to the surface as soluble complex ions. A volcanogenic model for the origin of banded ironformation, the sulfides, and the gold is favored.
