Abstract
Beryllium in the form of chrysoberyl was found at a new locality on the public domain on the Seward Peninsula. The beryllium is associated with altered dikes and marmorized limestone veined with fluorite-tourmaline-chrysoberyl veinlets. Although the chrysoberyl is fine grained and intergrown intricately with the fluorite and tourmaline, it has been separated and identified by X-ray diffraction. Specimens of ore selected randomly from areas of fluoritized limestone contain beryllium in the range .01 to 3.3 percent BeO. The area warrants detailed mapping and sampling, which will be done by the U.S. Geological Survey in 1962.
