Deposit PATCHES, VEINLETS AND IRREGULAR MASSES OF MN OXIDES OCCUR IN AT LEAST TWO HORIZONS IN TUFF MEMBERS OF THE BOLEO FM. MOST ORE BODIES LESS THAN 1 M THICK, TEND TO WEDGE OUT WITHIN 20 M. LOCALLY, A FOSSILIFEROUS TUFFACEOUS LIMESTONE MEMBER OF THE BOLEO IS IMPREGNATED WITH MN OXIDES AND CONTAINS MOLDS AND CASTS OF PELYCEPODS AND GASTROPODS REPLACED BY MN OXIDES.
