Finished logging, editing logs, preliminary sampling

Over the past few weeks we have continued to stay busy working on the rock core.  We finished logging at the end of August, and started right up on editing the logs for consistency and clarity.  So far, we have edited up to about Box 400 (~1670 feet). 
In addition to these activities, we also spent a couple days earlier this week taking preliminary samples from throughout much of the hole.  In the photo above there are 32 whole-rock samples made up of twenty aphyric rocks, seven intrusive units, and five picrites (>12% olivine).  The chemistry of these samples will be analyzed over the next couple months, and hopefully at least a few of them will be suitable for Ar-Ar dating as well.  The results of this preliminary work will then form the basis of further proposals to study the rocks in greater detail.
