HGRP Data

Rock Core Run Depth Log, Hole 1 – A record of the depth interval of each rock core run drilled.

Rock Core Run Depth Log, Hole 2 – A record of the depth interval of each rock core run drilled.

Working Core Box Log, Hole 1 – A record of the depth interval of rock contained in each core box.

Working Core Box Log, Hole 2 – A record of the depth interval of rock contained in each core box.

Hole 1 Lithologic column – You’ll want to click on the image below and zoom in to see the details.

Location map of the PTA2 and KMA1 boreholes and the cored sections of PTA2 and KMA1 – The map is on a topographic and bathymetric map of Hawai`i (bathymetric map from USGS, Eakins et al., 2003). Locations of a selection of additional cored boreholes drilled on Hawai`i are also indicated (red dots) (SOH4 1989, 2.0 km; SOH1 1991, 1.7 km; HSDP1 1993, 1.1 km; HSDP2 1999, 3.1 km) (see also Garcia et al., 2007) (MK – Mauna Kea, ML – Mauna Loa, KI – Kilauea, HU – Hualālai, Ko – Kohala). (b) The cored sections of PTA2 and KMA1 are indicated with their generalized volcanic facies and well information.

Example of raw borehole sonic waveform data analysis from PTA2 – Near- and far-receiver traces (50 cm spacing) with first arrival picking (FAP) results. The derived velocities are shown on the right side together with results from a separate semblance analysis (SA). The light-blue curve is the measured water wave velocity, and total GR is shown for depth correlation.

Borehole Logging Results for PTA2

Gamma ray log results compared to volcanic facies in the PTA2 and KMA1 boreholes – Two panels in the center display key intervals from PTA2 at a larger scale (b, c). Black lines display flow boundaries within pāhoehoe packages in the bottom middle panel.

Vp and Vs data from the PTA2 sonic log plotted against the volcanic lithofacies – Zoomed-in logs which both display data with a 1 m running average applied; black lines indicating flow and contact boundaries between similar facies. Ol rich stands for olivine rich.
