Tracking Kimberlites in Minnesota
Researchers believe they have found chemical traces and specific indicator minerals (such as garnets) within glacial sediments that may have originated from kimberlites. By tracking where past glaciers came from and where they scoured out rock and sediments, the researchers believe they may be able to ultimately find the source of these chemical deposits, and ultimately the potential Mother Lode.
Diamond bearing deposits in North America aren’t unprecedented. Canada began operations to mine for diamonds in the late 1990’s, and diamonds have also been found in Wisconsin and Arkansas as well.
