The Chilean accretionary wedge is part
of a Late Paleozoic subduction complex
that developed during subduction of the
Pacific plate underneath South America.
The wedge is commonly subdivided
into a structurally lower Western Series
and an upper Eastern Series. Understanding
the contact between both series
has been a long standing problem
and is fundamental for the understanding
of the evolution of the wedge system.
We show the progressive development
of structures and finite strain from
the least-deformed rocks in the eastern
part of the Eastern Series of the accretionary
wedge to higher grade schist of
the Western Series at the Pacific coast...
