Fold growth due to kink-band migration in repeated earthquakes, Sierra de Villicum, San Juan, Argentina

Creator:

Krugh, William C.

Abstract:

Growth strata geometries and deformed geomorphic surfaces reflect the shorttimescale growth of Sierra de Villicum (San Juan Province, Argentina). Accumulated deformation in repeated earthquakes is recorded by the structural geometry of deformed geomorphic surfaces. Through geologic mapping and topographic surveying, six strath terraces were identified on the eastern flank of...

Can growth strata identify individual paleoearthquakes and characterize fold kinematics? A case study from the La Laja fault system, Sierra de Villicum, Argentina

Creator:

Schultz, Emily S.

Abstract:

A large, damaging earthquake in 1944 on a blind thrust fault caused 60 cm of surface rupture on the subsidiary La Laja fault and additional unmeasured growth of an associated backlimb fold. Both the fold and fault are components of the La Laja Fault System (LLFS) located 25 km northeast...
