SAMPLE INFO : 71-PCL-39

Sample ID:	71-PCL-39
Station ID:	71-PCL-39
Latitude:	62.4833
Longitude:	-143.08528
Datum:	NAD83
Date Sampled:	1971-00-00
Sample Type 1:	Lava
Sample Type 2:	Flow
Field Lithology:	Basalt

Text Description:
Wrangell Lava. Basalt flows. Dark-gray to greenish-black, vesicular, fine- to medium-grained flows; locally porphyritic. Olivine, pigeonite, and abundant plagioclase (labradorite) occur as phenocrysts and in the groundmass. Locally, vesicles filled with chalcedony and minor calcite and chlorite. Rocks locally chloritized and altered to clay minerals. Individual flows generally thin (<5 m), although entire unit may exceed 100 m in thickness locally. K-Ar date on sample from Wait Creek (sec. 12, T. 6 N., R. 12 E.) yielded age of 13.9 +/- 0.8 m.y. (Deininger, 1972).
