This map shows most of the known occurrences of beryllium minerals and of rocks that contain 0.003 percent or more beryllium (0.01 percent Be0) in the United States (exclusive of Alaska and Hawaii). The occurrences are subdivided on the map according to genesis and size. The genetic types of deposits...
A new occurrence of beryllium minerals on the Seward Peninsula, Alaska
C.L. Sainsbury
1962, Open-File Report 62-114
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...
Geology of the Straight Creek tunnel site, Clear Creek and Summit Counties, Colorado, and its predicted effect on tunnel construction
