ORE DEPOSITS 6101 - Part 6 - Carlin Gold Deposits
- last year
Carlin-type gold deposits are sediment-hosted disseminated gold deposits. These deposits are characterized by invisible (usually microscopic and/or dissolved) gold contained in arsenic-rich pyrite and arsenopyrite. This dissolved gold is called "invisible gold" because it can only be found by chemical analysis. The deposit is named after the Carlin Mine, the first large deposit of this type discovered in Carlin Trend, Nevada.
