The greenstone, together with the rest of the Windermere in this region, is highly sheared, altered, and metamorphosed, except for a small exposed mass of relatively unaffected rocks near the community of Chewelah, Washington. K-Ar ages on whole rocks and mineral separates from the Chewelah area indicate the greenstone was probably extruded between 827 and 918 m.y. ago. This content is PDF only.
