Dredged Trachyte and Basalt from Kodiak Seamount and the Adjacent Aleutian Trench, Alaska
Blocky fragments of aegirine-augite trachyte (with accompanying ice-rafted gravels) were recovered from the upper slopes of Kodiak Seamount in several dredge hauls. An alkali basalt pillow segment was also dredged from a moatlike depression, at a depth of 5000 meters, near the west base of the seamo...
