SAMPLE INFO : 91CND19

Sample ID:	91CND19
Station ID:	91CND19
Latitude:	58.921578
Longitude:	-153.422947
Datum:	NAD83
Date Sampled:	1991-01-01
Sample Type 1:	Lava

Text Description:
Sample from same flow lobe as 91CND08. Upper part of this flow is a few to several feet higher than adjacent Spotted Glacier, thus has been beheaded by glacial erosion. Surface of flow is glacially polished and rounded. Porphyritic andesite. About 50% phenocrysts and microphenocrysts of plagioclase (up to 0.8 x 0.4 mm) and pyroxene (0.7 x 0.3 mm) with a microlite-rich brown glassy groundmass.
