First core of the project!

Aloha, we’re all excited around here as the night shift produced the first ~35′ of rock core for the project.  They had a rough time with some of the rig equipment though, so the day shift is currently doing maintenance on the drill rig. The core processing team examined and boxed up the core shown below, the rock looks like it all comes from a single thick pāhoehoe  flow. There are few fractures, and the core is chemically altered with secondary minerals (probably zeolites) filling most of the small vesicles and lining the larger ones. The olivine is quite altered and seems to be larger and more abundant with depth in the unit, indicating it settled downward as the hot flow cooled.

The first ~35′ of rock core dries quickly in the Lāna‘i sun
