The southern portion of Trail Ridge in Clay County, Fla., has been an important domestic source of altered ilmenite, zircon, and other minerals since 1949. The ridge as a physiographic feature extends in a north-south direction over 160 km and is 1 to 2 km wide. The ore is a fine- to medium-grained sand body that extends down from the crest of the ridge about 20 m. Average heavy-mineral content is about 4 percent. Over half of the ilmenite and zircon is contained in thin, dark laminae dipping 26° to 41 ° southwest; these laminae extend deep within the ore …
