Classification of Mineral Deposits | Geology for Investors
Most mineral deposits are formed by more than one process, so attaching a single label to them is difficult. Hence, there is a tendency to talk about Stillwater Complex type or Carlin-type gold deposits, which rather defeats the purpose of finding a general from the specific. There are two main approaches to mineral deposit classification.
