geology. the carlin type deposits show enrichment in the elements gold, arsenic, antimony, mercury, thallium and barium.this enrichment is created by hydrothermal circulation with a temperature of up to 300 c. the underlying rocks out of which the minerals are dissolved are normally silty carbonates, although also silicates and other sediments are possible.
