The dynamical origin of Hawaiian volcanism

Melt Generation by Plumes: A Study of Hawaiian Volcanism

The mantle plume underlying the Hawaiian Swell has been modelled numerically using a stationary steady axisymmetric plume under a solid conducting lid. A method of calculating the rate of melt production from the plume has been developed, and the total melt production rate, the residual depth anomaly and the geoid anomaly have been used to constrain the model. The plume has a central potential ...

ORIGIN OF ACID FLUIDS ON MARS: IMPACTS vs. VOLCANISM

Rare Earth Contribution to the Origin of Hawaiian Lavas

Rare earth abundances were determined by neutron activation in twenty Hawaiian lavas and one diabase of known chemical and mineralogical compositions. These results demonstrate a systematic relationship between the absolute or relative rare earth abundances and the petroehemistry of these rocks. Three distinct lava groups are recognized. These correspond to: (1) tholeiites, (2) alkali series, (...

Nursery origin of yellowfin tuna in the Hawaiian Islands

Stable isotopes of carbon (δ13C) and oxygen (δ18O) in otolith cores (first 2 mo of age) of young-of-the-year (YOY) yellowfin tuna Thunnus albacares were used as natural tracers to predict the nursery origin of sub-adults (age-1) collected from the Hawaiian Islands. YOY fish were first collected from nurseries throughout the western and central Pacific Ocean (WCPO) to determine whether δ13C and ...
