Abstract

Volcanic dikes are emplaced along ~30 km of the Socovos Fault trace. These dikes intruded the fault zone through different structures generated along the fault, providing a singular framework to inquiring the relationships with transcurrent tectonics. The volcanism age helps us to constrain the fault timing, to integrate with regional volcanism and to inquire about its origin and the movement of the Socovos Fault. 40Ar/ 39Ar ages indicate a westward propagation of volcanism that lasts ~ 2 Ma from 9.3 Ma to 7.15 Ma, with a propagation rate of 5 mm/year, consistent with the estimated strain rate for the Miocene. These data together with the supposed origin of lamproites in the lithospheric mantle indicate that there must be an active lithospheric structure that allows the continuous ascent and emplacement along the Socovos Fault, showing both the lithopheric structure and the Socovos Fault a coupled movement, indicating a close genetic relationship.
