Hawaii Scientific Drilling Project: Summary of Preliminary Results

摘要: Petrological, geochemical, geomagnetic, and volcanological characterization of the recovered core from a 1056-m-deep well into flank Mauna Kea volcano in Hilo, Hawaii, downhole logging fluid sampling have provided unique view evolution internal structure major oceanic unavailable surface exposures. Core recovery was ~90%, yielding time series fresh, subaerial lavas extending back to ~400 ka. Results this 1993 project provide basis for more ambitious drill 4.5 km deep nearby location with goal recovering an extended, high-density stratigraphic sequence lavas.
