Title: Submarine Geology of Ranger Bank, Mexico

Author(s): K. O. Emery (2)

Abstract:

A large collection of bottom samples and underwater photographs from the top of a 67-fathom flat-topped bank off Baja California, Mexico, was studied. The data indicate that wave action bevelled Jurassic (?) metamorphic and Miocene (?) volcanic and sedimentary rocks during a time of greater relative emergence. After submergence of the bank or rise of sea-level, the top of the bank was partly veneered by glauconite and organic sediments composed of Foraminifera and small pieces of mollusks. Abundant phosphorite pebbles on the surface may be derived from underlying Miocene strata. The loose sediments found on the bank are completely unlike those of the truncated rocks and are also different from the muds of surrounding deeper areas.
