FY79 Lava Lake Drilling Program - geoscience studies; plans and results

Abstract

Fifteen experimental studies were planned for the geoscience studies portion of the FY79 Lava Lake Drilling Program at Kilauea Iki Lava Lake, Hawaii, grouped under headings of petrologic, thermal, strength, liquid/permeability, electrical, and other. This report gives a location, purpose, description, and feasibility analysis for each experiment. A "Results" section for each experiment includes data gathered and analysis to date, where available. Later reports on completed data analyses and conclusions will be published as warranted .

Drilling report and core logs for the 1981 drilling of Kilauea Iki lava lake (Kilauea Volcano, Hawaii), with comparative notes on earlier (1967-1979) drilling experiences

“…Shaw on 1/5/77. The re-entry history of KI76-2 as shown here differs in several details from that given in Colp (1979).…”

Major-element compositional data and thermal data for drill core from Kīlauea Iki lava lake, plus analyses of glasses from scoria of the 1959 summit eruption of Kīlauea Volcano, Hawaii

“…The first drilling episode took place shortly thereafter; results from the 1960-1962 drillings were reported in Richter and Moore (1966). The lava lake was drilled subsequently in , 1975in , 1979in , and 1988in (Helz and others, 1984Helz and Wright, 1983;Helz, 1993). The locations of the leveling network and boreholes are shown in map view ( fig.…”

“…Dashed lines indicate that the rhyolitic residual glass is metastable. Thermocouple profiles (Colp, 1979) are in appendix table 2.4. The glass geothermometry data are from appendix table 1.1.…”
