(1) Reflex III core orientation device
(2) New HQ bit
(3) Drilling the first core run
The morning was spent with a acontinuations of set up and training. IDS showed us how the core is oriented using the Reflex III coring device (1). An HQ bit was attached to the drill string (2). By 12:30 PM, we had the first core (3, 4, 5, 6, 7, 8, 9) which consisted of rubbly basalt or "aggutinite". 3 ft was drilled and 3.5 ft was recovered.
Drilling proceeded until a depth of 40 ft at which point casing was inserted. Drilling proceed until 45 ft at which time coring was stopped for the day at 6:45 PM.
The rest of the cores were all in basalt and various other flavors of basaltic effusive rocks with vugs and fractures (10, 11, 12).
