SAMPLE INFO : 09KCNYE006
Sample ID:09KCNYE006
Station ID:09KCNYE006
Latitude:52.17337
Longitude:-175.49237
Datum:NAD83
Date Sampled:2009-01-01
Text Description:
Hand sample; >20g. Porphyritic ol cpx pl lava. Probably the same as other older lava samples today (002, 004). Light gray (25%k) basalt. Presumably similar to 02 and 04, but the lighter gms makes it easier to see mineralogy. ~20% total phenocrysts with plag (1-2mm) ~= cpx (1-2mm) > ol (1mm). Olivine is fairly abundant and coarse. Note that h.s. photo contains unusual 2cm inclusion of very fine grained (0.25mm) equigranular holocrystalline plag+ol+cpx mass w/ abt inter-crystal voids and vesicles. This was beach outcrop and it was difficult to find fresh stuff - hard to break far enough into the rock.
