Mid-Cretaceous Hawaiian rocks in Kamchatka
Scientists from IFM-GEOMAR found geochemical evidence for preservation of ~100 m.y. old Hawaiian hotspot rocks in Kamchatka (Far-East of Russia). New trace element and isotope data show that the Hawaiian mantle plume is very persistent in composition during millions of years and originates from a la...

| Summary: | Scientists from IFM-GEOMAR found geochemical evidence for preservation of ~100 m.y. old Hawaiian hotspot rocks in Kamchatka (Far-East of Russia). New trace element and isotope data show that the Hawaiian mantle plume is very persistent in composition during millions of years and originates from a large chemically isolated mantle domain at the Earth core-lower mantle boundary. |
