Extrusive rocks of Miocene and younger age have been dredged from the submerged insular slopes of the arcuate, 2,220-km-long Aleutian Ridge. Hornblende dacite porphyry recovered at station 70-B29 (lat 52.6/sup 0/N, long 174.8/sup 0/E; depth, 700 m) was extruded less than 610,000 yr ago. The dacite crops out approximately 80 km west of Buldir Island, the westernmost volcanic edifice of the 2,550-km-long Aleutian volcanic chain. The submerged dacite extends the westward limit of this chain of… CONTINUE READING
