Digant looking at core alteration

We restarted drilling operations on Monday, November 14. This is last Big Push. Depth about 1188.7 meters, bottom hole temperature about 93C. November 20 -- were at 1364.6 meters below surface. There has been a lot of highly altered basalt that have a greenish tint to them. A lot of brecciated basalt, subaqueous hyaloclastites with sediment mixed in. Sometimes it appears to be a basalt but is very rich in a green clay. Drilling is going smoothly. They had to install a blow-out preventer (BOP) which is mandatory when they get higher temps. Last bottom hole temp 96.8ÂșC.
