USA's Oldest Rocks are From Michigan!
Although most scientists consider the oldest rock in the world to be Canada’s Acasta Gneiss, turns out the oldest rocks in the U.S. are from Gogebic County in the Upper Peninsula (UP) of Michigan. In the latest edition of GSA Today, they reveal that the Watersmeet Gneiss is estimated to be 3.62 billion years old!
MGS geologists have been actively mapping the Watersdome region in the UP and we are looking forward to sharing our findings with everyone! Keep an eye out for our next edition of the MGS Core Quarterly for more details about the oldest rocks in the U.S.
from the Watersmeet Dome.

Update about Michigan's Potash Deposit and Research
Dr. William Harrison recently described Michigan’s potash deposit and the research we have been conducting about it. The article discusses the history of the deposit, where it is, and why it is particularly important now. He discusses the collection of potash rock cores that we preserve at MGRRE from 77 different wells in 9 counties. Research by MGRRE staff and students identified the geologic and stratigraphic distribution of this deposit, and analytical testing by industry has confirmed it to be the highest grade potash known throughout the world.
This story was also featured in the latest issue of Geologically Speaking, a Michigan Section AIPG Publication; see page 11.
