Apollinaris Patera
This view of Apollinaris Patera, shows characteristics of
an explosive origin and an effusive origin. Incised valleys in most of the flanks of
Apollinaris Patera indicates ash deposits and an explosive origin. On the west side
(left), landslides that have shaped its surface also indicate ash deposits. Towards
the south flank, a large fan of material flowed out of the volcano. This indicates
an effusive origin. Perhaps during its early development Apollinaris Patera had an
explosive origin with effusive eruptions taking place later on.
