Dust provides ecosystem-sustaining nutrients to landscapes underlain by intensively weathered soils. Here we show that dust may also be crucial in montane forest ecosystems, dominating nutrient budgets despite continuous replacement of depleted soils with fresh bedrock via erosion. Strontium and neodymium isotopes in modern dust show that Asian sources(More)
Late Quaternary, post-shield lavas from the Mauna Kea and Kohala volcanoes on the Big Island of Hawaii have been dated using the Ar/Ar and U–Th/He methods. The objective of the study is to compare the recently demonstrated U– Th/He age method, which uses basaltic olivine phenocrysts, with Ar/Ar ages measured on groundmass from the same samples. As a(More)
