  abstract = {{I}n the {G}uateque-{M}edina area, {P}aleozoic basement and {M}esozoic rift basins have been uplifted and exhumed during the {A}ndean orogeny (12 {M}a to present). {S}urface exposures and subsurface data constrain the deformation style and the rift geometry. {W}e have mapped a regional transect and restored a cross section. {W}e have also reconciled existing stratigraphic data, from cordillera, foothills and foreland basin, and have added new data of our own. {I}n {E}arly {C}retaceous shales, there is evidence for fault-controlled sedimentation. {A} brecciated evaporitic layer, which is locally emerald bearing, has acted as a regional detachment. {T}he underlying basement, composed of {P}aleozoic sediments, crops out as the {Q}uetame {M}assif. {I}t was uplifted during the {A}ndean orogeny on a series of high-angle reverse faults. {T}he main {SE}-verging {T}esalia fault has resulted from {A}ndean reactivation of an {E}arly {C}retaceous normal fault, which bounded a half-rift. {A} series of {NW}-verging back-thrusts may have resulted from {A}ndean reactivation of {P}aleozoic faults. {B}etween the back-thrusts and the {T}esalia fault is a basement pop-up. {I}t may be part of a flower structure, because components of right-lateral slip have been identified. {T}hese are attributed to eastward subduction of the {N}azca plate beneath {S}outh {A}merica. {I}n general, the style and timing of {A}ndean deformation in the {G}uateque-{M}edina area are compatible with the plate tectonic setting of the northern {A}ndes.},
