Airport Amphibolite and Gorgon
We started off the day at Shark Cove to collect some conglomerate
cobbles for my thesis project! I would say it was pretty successful.
With help from Julia and Dr. P-D (below), we collected around 13
samples from the surrounding melange matrix. I am excited to get
started on my senior thesis work and see our hard days out in the field
sampling pay off.
After an awesome start and a lunch break we ventured back to the
amphibolite exposure near the end of the airport runway. The goal was
to sample more block core and rind traverses or pairs. Unfortunately,
that did not go as planned. The rocks here are just so weathered
and that made it was difficult to find a suitable piece. Instead, we
saw some amazing amphibole crystals. They were HUGE and possibly the coolest
amphibole crystals I have seen on the trip. We also got a good amount
of anthophyllite reaction zones and surrounding metaultramafic rock.
Then we went to one of my favorite outcrops on Catalina....Gorgon. Mega
garnet amphibolite blocks all over the hill side, we stayed briefly to
just collect some of our favorites. This is hard for me because how
could you pick a favorite?! They are all beautiful! We made out choices
and headed home satisfied with the work we had done for the day.
We had dinner at The Harbor Reef again and drank Buffalo Milk (yummy!)
and then walked on the beach before heading home.
