Research Abstract	In order to reconstruct the paleolatitude for the last glacial sedimentary units of the Paleoproterozoic Huronian glacial epoch, I performed paleomagnetic measurements of sedimentary rocks from the Marquette Range supergroup, USA. Mean paleolatitude values obtained are ranging from 11 to 21 degrees. However, these characteristic remanent magnetizations do not pass some field tests, suggesting that they possibly are secondary remanences.
