0214 - Two different overlapping enclosures at Moreiros 2?

This is what the geophysics interpretation might suggest. 

General interpretation of Moreiros 2 geophysics (magnetogram from Helmut Becker)

A first one (A) presents mainly palisade structures and has a more irregular design, following the layout of topography.

A second set of enclosures (B), partially overlapping the first, is characterized mainly by ditches, with patterned features (namely gates) and with different designs, more concentric and that don´t respect the topographical layout.

The two possible sets of enclosures.

The two inner ditches of this second sequence (the only ones archaeologically excavated, have been dated from Late Neolithic. That means that the first sequence of enclosures is earlier, maybe from a middle Neolithic. To be true, that would take back a little the emergence of enclosure in Alentejo (as it happens in central Portugal with Senhora da Alegria enclosures).

It would also be interesting to date the outside ditches of the second sequence, the ones that have a sort of polygonal design, for the only parallel we have for that layout is in Chalcolithic walled enclosures (S. Pedro, Porto das Carretas).
