| Abstract: | In the Archean of Western Greenland a tungsten province ca. 300 km long and up to 120 km wide has been discovered with extensive banded amphibolites containing up to 2% W and 0.16 ppm gold. The tungsten occurs as scheelite which is associated with tourmalinites and strata-bound tourmaline-rich layers in amphibolites of presumed tuffaceous origin and with an iron-formation containing high amounts of tungsten, zinc, copper, lead, molybdenum, and tin. The scheelite is shown to be strata-bound and of submarine exhalative origin. |
