Figure F13. Relative borehole resistivity as imaged by LWD (golden/brown columns) compared to the presence of low temperature anomalies in recovered cores as imaged by IR camera scans (blue spikes). The resistivity data show a clockwise scan from north of the borehole wall. Light shades represent higher resistivity. Horizontal bands are parallel to strata, whereas S-shaped bands represent steeply dipping structures. IR anomalies represent the difference between local and background temperature. Background temperature was determined by eye and can be due to many factors, including air temperature on the catwalk and coring method. The base of the GHSZ (BGHSZ) is defined by the BSR, Horizon A, and the top of accretionary complex as defined by increased fracturing and variable density in the LWD data are also shown.
