SAMPLE INFO : 09KCnye104
Sample ID:09KCnye104
Station ID:09KCnye104
Latitude:52.16536
Longitude:-175.5206
Datum:NAD83
Date Sampled:0000-00-00
Sample Type 1:Other
Text Description:
Peregrine glaciovolcanic deposits. ~1.5m l-max boulder. Visible part of mode is 4-5mm faceted cpx. These large blocks are apparent lithics in the scoriaceous "pepperite" thus >= same age. Hopefully this block is datable and should be among the oldest rocks on the island. [INSECT collected: fly on rock in vial #106919.]. Medium gray (35%k) lava with faint greenish cast. 5% stubby prisms of cpx to 3x5mm. Some ambiguity about these, black, not emerald green in hand specimen, but with hand lens they seem to be vitreous olive green, unlike amphibole -- on the other hand, some prismatic section seem to have amphibole angles]. Sparse plag phenocrysts as 3mm long laths. Abundant plag in gms. Gms fine-grained sugary holocrystalline.
