We spent our day in the amphibolite
facies working on sampling blocks
and rinds for Julia's MS project. In the morning we tried sampling with
our rock saw. This rock saw has been quite the experience all along. We
got it to work and made four parallel slices in a rock. However, after
those four slices, it decided it had enough, and we couldn't get it to
start again. Also, when we tried to chisel out the slices, they came
out in flakes - not ideal.
So, for the afternoon, we decided to
go to one of my favorite locations
on the island - Ripper's Cove. There are several loose boulders that
are garnet amphibolite blocks that have rinds on the edges. We spent
our afternoon hammering away at several of these and came away with
several samples. While some of the sampling was frustrating, I believe
we came away with the best samples we could - a success!
