Lemkeinis aseamountin theWestern Pacific Ocean,west ofKwajalein.[1]
It is part of theMagellan Seamounts[2]and is avolcanicseamount covered with sediments.Ferromanganesecrusts occur in some places.[3]Basaltsin the form ofpillow lavasaltered toclayandzeolithshave been recovered from Lemkein.[4]Like other Magellan Seamounts, it formed south of the equator and was moved to its present-day position byplate tectonics.[5]
