Which would the Andean-type margin not have more of, in comparison to an Aleutian-type margin?
A)complicated crustal compressional structures
B)felsic pyroclastics
C)deformed high pressure/low temperature accretionary wedge rocks
D)subaqueous mafic pyroclastics close to the volcanoes

Question

Quizplus · Accepted Answer

Andean-type margins are characterized by continental volcanic arcs, leading to more felsic pyroclastics and complex crustal structures due to the subduction of an oceanic plate beneath a continental plate. Aleutian-type margins, being oceanic-oceanic plate boundaries, are more likely to have subaqueous mafic pyroclastics close to the volcanoes due to the nature of the oceanic crust and its volcanic activity.
