Chile Triple Junction
The
Chile Triple Junction
(or
Chile Margin Triple Junction
) is a geologic
triple junction
located on the seafloor of the
Pacific Ocean
off
Taitao
and
Tres Montes Peninsula
on the southern coast of
Chile
. Here three
tectonic
plates meet: the
South American Plate
, the
Nazca Plate
, and the
Antarctic Plate
. This triple junction is unusual in that it consists of a
mid-oceanic ridge
, the
Chile Rise
, being
subducted
under the South American Plate at the
Peru–Chile Trench
.
