Abstract
The subandean Ucayali Basin is an active fold and thrust belt propagation, which constitutes part of the<br>wedge-top depozone of the Peruvian Amazonian retroforeland basin system. In the North, the Ucayali<br>Basin is limited from the Marañón basin by the NW-SE overthrust Contaya Arch. In the east, the Ucayali Basin<br>reaches the NNW-SSE trend of the Brazilian Moa Divisor structure, which disappears progressively to the<br>south on the northern flank of the Fitzcarrald Arch.
