Wilde's Guyot  


expandable pdf version

     An example of a seamount, the Wilde guyot. A guyot is a seamount
with a flat top created by wave action  when the seamoune sea level. As the seamount is 
carried by plate motion, it gradually sinks deeper below sea level. 
 The depth was contoured from echo sounder data collected along the ship track 
(thin straight lines) supplemented  with side-scan sonar data. Depths are in units of 100 m.

  white, fine-grained limestone or ash, similar to ARIES 19D, except conglomerate has small
  basalt pebbles and is suboradinate to white fine-grained material. Mn crust is up to 3 cm thick
  on some specimens. Slabs of rock are up to 2 feet across. Foraminifera in white material are of
  Eocene age.
