The application of Diamond Exploration Geoscientific Information System (DEGIS) technology for integrated diamond exploration in the north-central United States of America
Abstract. Discovery of diamondiferous kimberlite in northwestern Canada, and occurrences of similar intrusions and alluvial diamonds elsewhere, suggest North America is fertile ground for economic primary diamond deposits. Using a Diamond Exploration Geoscientific Information System (DEGIS) to develop an exploration model, we identified four areas of permissive terrain in the northcentral United States: Wisconsin-Upper Peninsula of Michigan, southeastern Wyoming, North Dakota-Minnesota-Ontario, and northwestern Iowa. Permissive areas feature lithosphere that is > 1.6 billion years old and > 150 km thick; and prospective zones within this terrain contain point and linear features that are associated with kimberlite and lamproite emplacement.
