SAMPLE INFO : 09KCNYE003M
Sample ID:09KCNYE003M
Station ID:09KCNYE003M
Latitude:52.17463
Longitude:-175.49533
Datum:NAD83
Date Sampled:2009-06-12
Field Lithology:Gabbroic
 Text Description:
Matrix separate from 09KCNYE003. Coarse, equigranular cpx-hb-pl rock. This one sampled because it looks like it has gms/interstitial glass preserved. Question, is this interstitial melt the main-phase magma? Coarse-grained amph plag gabbro. Color index ~60, mean grain size ~3mm. But some amphibole crystals are crystallographically coherent for up to 3.cm - these are poikilitic. This specimen is unusual compared to others in this unit because it contains zones of disseminated intergranular melt from a few mm to 1 cm across. Melt is 60%k, finely vesicular and sparsely phyric. Sample 09KCnye300m is ~7g of handpicked intergranular magma from 472 g of coarse crushed material. This separate is about 90%melt and 10% crystal fragments.
