Abstract
Seismic profiles on the Eastern front of the Andean belt of Bolivia show pre-existing pre-Devonian thrust structures. The ramp anticlines are located beneath an erosional unconformity at the bottom of the Mesozoic sediments. These pre-Devonian structures are probably late Ordovician or Eocambrian in age and seem to have influenced the distribution of Paleozoic sediments as well as subsequent deformations. The ramps of the pre-Devonian thrust system were slightly reactivated during the Cenozoic migration of the Andean thrust system front. There is an abridged English version. -from English summary
