The Origin and Evolution of Seamounts

This special section is the outcome of a symposium held at the Lamont-Doherty Geological Observatory November 17th, 1982, on the origin and evolution of seamounts. The topic for the symposium arose from the realization that although there is now a wealth of new ideas on the geology, geophysics, and geochemistry of the ocean floor, the study of seamounts has been relatively neglected despite their great importance to plate tectonics.

      Two views of Hawaiian plume structure (pages 5308–5322)

      Albrecht W. Hofmann and Cinzia G. Farnetani

      Version of Record online: 20 DEC 2013 | DOI: 10.1002/2013GC004942

      Key Points

      • Small-scale heterogeneities do not explain geochemical structure Hawaiian plume
      • Rejuvenated volcanism is derived from the fertile underside of the plume
      • Its source comes from the upper portion of the thermal boundary layer

      Version of Record online: 4 OCT 2013 | DOI: 10.1002/ggge.20267

      Key Points

      • 40Ar/39Ar ages for new samples from the Hawaiian-Emperor Seamount Chain (HESC)
      • Hawaiian-Emperor Bend (HEB) is at least 47.5 Myr old
      • Remarkably linear age-progression for 1900 km in the central part of the HESC

    1. Re-Os isotope and platinum group elements of a FOcal ZOne mantle source, Louisville Seamounts Chain, Pacific ocean (pages 486–504)

      Maria Luisa G. Tejada, Takeshi Hanyu, Akira Ishikawa, Ryoko Senda, Katsuhiko Suzuki, Godfrey Fitton and Rebecca Williams

      Version of Record online: 19 FEB 2015 | DOI: 10.1002/2014GC005629

      Key Points:

      • The LSC mantle source has a small range of mantle-like (187Os/188Os)i
      • The Os isotopes and PGE contents suggest little or no recycled components
      • The PGE variations are best explained by sulfide-present low-degree melting

      Version of Record online: 16 JUN 2014 | DOI: 10.1002/2014GC005298

      Key Points

      • New geomagnetic paleointensity data in Late Cretaceous and earliest Paleocene
      • VADMs obtained are close to the long-term average during the last 200 Myr
      • No discernible relationship between polarity length and paleointensity

      Version of Record online: 11 JUN 2014 | DOI: 10.1002/2014GC005288

      Key Points

      • LSC mantle source is surprisingly homogeneous
      • A Hawaiian-type tholeiitic shield-volcano stage is absent from LSC seamounts
      • LSC mantle source is isotopically distinct from Ontong Java source
