Seamount in the Pacific Ocean
Lemkein is a
seamount in the
Western Pacific Ocean , west of
Kwajalein .
It is part of the
Magellan Seamounts
[2] and is a
volcanic seamount covered with sediments.
Ferromanganese crusts occur in some places.
[3]
Basalts in the form of
pillow lavas altered to
clay and
zeoliths have been recovered from Lemkein. Like other Magellan Seamounts, it formed south of the equator and was moved to its present-day position by
plate tectonics .
