A Morphological and Mineralogical Study of the Gray Hydromorphic Soils of the Hawaiian Islands!
Gray hydromorphic soils are imperfectly to poorly drained soils that occur on the coastal fringes of the Hawaiian Islands on surfaces of Pleistocene to Recent age. Mottling is characteristic of the soils, and gley horizons occur in the more hydromorphic soils in the group . As the soils become hydromorphic, soil color values increase and structures deteriorate. Halloysite is the dominant clay m...
متن کاملRare 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, (...
متن کاملFALSE KILLER WHALE (Pseudorca crassidens): Hawaiian Islands Stock Complex – Main Hawaiian Islands Insular, Northwestern Hawaiian Islands, and Hawaii Pelagic Stocks
STOCK DEFINITION AND GEOGRAPHIC RANGE False killer whales are found worldwide mainly in tropical and warm-temperate waters (Stacey et al. 1994). In the North Pacific, this species is well known from southern Japan, Hawaii, and the eastern tropical Pacific. There are seven stranding records from Hawaiian waters since 1974 (Nitta 1991; Maldini et al. 2005, NMFS PIR Marine Mammal Response Network ...
متن کاملGeology and Volcanology of the Hawaiian Islands
This article summarizes the present state of knowledge of the geology of Hawaii. It tends to concentrate on aspects not usually covered by review articles. Current ideas on hotspots and mantle plumes are applied to the specific example of Hawaii, the eight volcanic systems currently nourished by the hotspot are identified, and gross differences in magma-supply rate are related to position of th...
متن کاملOsmium-isotope variations in Hawaiian lavas: evidence for recycled oceanic lithosphere in the Hawaiian plume
Isotopic heterogeneity in Hawaiian shield lavas reflects the presence of two distinct recycled components in the Hawaiian plume, both from the same packet of recycled oceanic lithosphere. Radiogenic Os-isotopes and anomalously heavy oxygen-isotopes in Koolau lavas reflect melt generation from recycled oceanic crust plus pelagic sediment. In contrast, Kea lavas have unradiogenic Os-isotopes but ...
