Controls for ore emplacement

  • Manganese Deposits Of The Region Are Associated With Spilites (Park, 1942, P. 311-312). Manganese Mineralization May Be Either Disseminated In Replacement Bodies Or Volcanogenic Exhalative/Diagenetic Bodies (Sorem And Gunn, 1967).

Comments on the geologic information

  • THE CRESCENT FORMATION ON THE OLYMPIC PENNINSULA CONSISTS OF PALEOCENE? AND EOCENE PILLOW BASALTS COMPOSITIONALLY SIMILAR TO OCEAN RIDGE BASALTS (SNAVELY, 1987, P. 306-308). CLASTIC ROCKS AND ASSOCIATED BASALTS OVERLIE THE CRESCENT FORMATION HOST MANGANESE MINERALIZATION AT THE BLACK HUMP DEPOSIT )TABOR AND CADY, 1987, GEOL. MAP).
