SAMPLE INFO : KC11NYE005
Sample ID:KC11NYE005
Station ID:KC11NYE005
Latitude:52.17959
Longitude:-175.52595
Datum:NAD83
Date Sampled:2011-01-01
Text Description:
Hand sample; >20g. Large (3 to 5 m) beach boulder with radial fractures at edge 3-5 cm wide and exending 30-40 cm into interior of boulder before anealing. Massive block interior. Block itself is light matte gray grading to orangish-purple towards edges. This sample must have come off the cliffs above which form the tallest backdrop to Tundering Cove. (Hand samples KC11nye03, 04 -- collected from the base of the cliff itself ~100m asl confirm this, although they are friable ashy lava base, rather than decent samples.) This unit is distinct from all other massive lavas in that it has ABUNDANT LARGE AMPHIBOLE PHENOCRYSTS. This boulder also contains gabbro inclusions.
