Lemkein is a seamount in the Western Pacific Ocean, west of Kwajalein.[1]
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.[4] Like other Magellan Seamounts, it formed south of the equator and was moved to its present-day position by plate tectonics.[5]
