Description: Geology of the Iron Mountain Kimberlite District. Describes kimberlite discoveries, diamonds and possibilities for additional discoveries. Contains detailed geological map. The author investigated this kimberlite district (the second largest kimberlite district in the US) as a mapping project and found it to represent a classical, deeply eroded, dike-blow complex. The geochemistry of the kimberlites suggest that all should contain diamonds - to date, one 0.3 carat diamond was recovered from very limited sampling.
Notes: One of the two largest kimberlite districts in the U.S.
