The development and testing of the Magma-Metal Series Chemical Classification of Igneous Rocks and Mineral Deposits began in the 1970’s. Since the early 1980’s, development and testing of the classification has been done by MagmaChem Exploration, Inc. The MagmaChem Classification was originally applied to mineral exploration, leading to the discovery of 21 metal deposits on 3 continents, and has been used as a predictive tool to help unravel the complex geology of regions such as the western United States.
The following is an historical overview and generalized description of the MagmaChem Classification, and how it has contributed to the mineral deposit discoveries. The overview is written chronologically and divided into four decades (Figure 1).
