The
Chonos Metamorphic Complex
is an
accretionary complex
composed of
metamorphic rocks
located in western
Aysen Region
,
Chile
. The deposition of the
sedimentary
protoliths
occurred in the
Triassic
and they were later
metamorphosed
in the
Jurassic
. The formation has been subdivided into a highly deformed Western belt and an Eastern belt where sedimentary structures are preserved.
