Introduction
This data set includes minimum and maximum growth onset ages computed from the vertical separation diagram (VSD) analysis in table ts01.pdf, a representative wedge-frontcrossing seismic reflection line that images three adjacent wedge-front structures and the corresponding vertical separation diagrams in figure fs01.pdf, fault parameters distributions from the elastic dislocation modeling in figure fs02.pdf, examples of the data and modeling results using offset horizons are in figure fs03.pdf, and the profile-based analysis of wedge-front fault dip-slip rates using the composite dip-slip rate estimates for each of the profiles in figure fs04.pdf.
1. ts01.pdf
Minimum and maximum growth onset ages computed from the VSD analysis. See the main text for a more detailed description of the method. For the La Vertiente we estimate a

growth onset age from the kink in the VSD curve corresponding to horizon 3 in main text
Figures 4C and 4D. The additional La Vertiente estimate (*) is associated with the cessation of growth strata formation and corresponds to horizons 4/5 in Figures 4C and 4D of the main text.
1.1 Column "Structure", name of wedge-front structure
1.2 Column "Line", seismic line number corresponding to wedge-front structure
1.3 Column "Lon", degrees, longitude of wedge-front structure
1.4 Column "Lat", degrees, latitude of wedge-front structure
1.5 Column "min", ka, minimum age of wedge-front structure
1.6 Column "max", ka, maximum age of wedge-front structure

(Top) Representative wedge-front-crossing seismic reflection line. See Figures 2 and 3G in the main text for the line location. Interpreted horizons across portions of the adjacent
Ubicuy, Tacobo/Curiche, and Guanacos structures used for the vertical separation diagram
(VSD) analysis are shown in red. Well TCB-X2, which pierces the Tacobo/Curiche structure, is also shown. (Bottom) VSD’s for the structures imaged in Line 5072-21. The kink in the curve is assigned to growth onset. A detailed description of the VSD method is provided in the methods section of the main text. MF=Mandeyapecua fault.

Fault parameters distributions from the elastic dislocation modeling. The modeling locations are indicated by colored circles in Figures 6 and 8 in the main text and Figure fs04. For example, we model fault parameters at 7 locations along the length of the
Guanacos structure. The resulting mpds from top to bottom correspond to the colored circles on the map overlain on the Guanacos fault trace from north to south. Expanded views of the parameter distributions for the Mandeyapecua (D2) and La Vertiente faults are shown in Figure fs03.

Modeling results using offset horizons. (Top) Mandeyapecua fault. The top left panel shows the interpreted seismic line from Uba et al. [2009] with the digitized horizon used in the modeling in red. The top right panel shows the depth-converted horizon in red and the best-fit model output and fault parameters in blue. The regional horizon constructed by fitting a straight line through the interpreted horizon endpoints is shown in black. Also shown are the probability distributions for the 5 model parameters with the global minimum indicated with a vertical red line. (Bottom) La Vertiente fault. The top left panel shows the seismic section and offset horizon used to model La Vertiente deformation. The top right panel is the same as for the Mandeyapecua fault with the data horizon in red, the best-fit model horizon in blue, and the regional horizon used to create the model in black.
The fault parameter probability distributions are shown in the bottom panel with the red vertical line indicating the model space global minimum. fs04.pdf
Profile-based analysis of wedge-front fault dip-slip rates using the composite dip-slip rate estimates for each of the profiles in contrast to the individual dip-slip mpds that are used in
Figure 8 of the main text. (Left) Map showing the numbered profile locations. (Right) Fault and composite dip-slip rate mpds for the profiles. Distribution colors correspond to the different faults and the composite estimates are in red. Profiles 5-8 include the minimum
(solid blue line) and maximum (dashed blue line) MF dip-slip rates from Figure 7 of the main text. The minimum mpd and corresponding composite estimate are dashed. For comparison, we indicate the 7-13 mm/yr range of shortening rates determined from geologic studies and the GPS-based wedge-loading rate of ~10 mm/yr.
