Axial seamount basalts in P3 segment of Phoenix Ridge, Drake Passage, Antarctica: K-Ar age determination and geochemistry / Jong Ik Lee, Soon Do Hur, Mi Jung Lee, Kyu Jung Kim, Keisuke Nagao.

Title: Axial seamount basalts in P3 segment of Phoenix Ridge, Drake Passage, Antarctica: K-Ar age determination and geochemistry / Jong Ik Lee, Soon Do Hur, Mi Jung Lee, Kyu Jung Kim, Keisuke Nagao.
Author(s): Lee, Jong Ik.
Hur, Soon Do.
Lee, Mi Jung.
Kim, Kyu Jung.
Nagao, Keisuke.
Date: 2003.
Language: Korean.
In: Ocean and Polar Research. (2003.), Vol. 25(1) (2003)
Abstract: Presents results of whole-rock geochemical analyses and K-Ar age determination of basalts from axial seamount in Drake Passage. Younger ages towards crest of seamount indicate growth of submarine volcano by central eruptions; composition of trace and rare earth elements indicates formation by hotspot activity rather than seafloor spreading. Transitional alkaline- and subalkaline-series seamount basalts contain small amounts of normative quartz and olivine. Volcanic activity stopped when basaltic magma reached mild alkaline composition.
