File S1. This Excel file contains 3 sheets. Sheet 1 (“original data”) consists of major element and trace element geochemical data from sample ZAP-44A (fresh quartz diorite) and ZAP-44B (altered quartz diorite adjacent to a vein) in their original format. These geochemical analyses were carried out via CP-AES and lithium borate fusion ICP-MS at ALS Minerals in Reno, Nevada. Sheet 2 (“crustal thickness”) is a compilation of La/Yb and Sr/Y data from the Papudo-Quintero complex from Parada et al. (1992, 1999) and sample ZAP-44A, along with corresponding crustal thickness calculations using the Profetta et al. (2015) and Sundell et al. (2021) calibrations.

File S2. This Excel file contains all the structural data from this study, including locations of all stations with coordinates in latitude-longitude (decimal degrees) and UTM WGS 84 (sheet “stations”), orientations of mafic dikes (sheet “mafic dikes”), orientations of granitic dikes (sheet “granitic dikes”), orientations of V1 and V2 veins (sheet “veins”), orientations of en echelon V1 veins and calculations of ideal shear directions (sheet “en echelon veins”), geometric and kinematic data of all faults (sheet “faults”), orientations of magmatic foliation (sheet “magmatic fabric”), geometric and kinematic data of all discrete (cm-scale) shear zones, including calculations of ideal shear directions and relevant observations (sheet “discrete mylonitic shear zones”), fabric data from high-temperature, m-scale shear zones (sheet “Hi-T shear zones”), and fabric data from the Zapallar shear zone (sheet “Zapallar shear zone”). “n/a” = not applicable (cells with no value)

File S3. This Excel file contains the coordinates of all samples collected in this study, in latitude-longitude (decimal degrees) and UTM WGS 84 along with comments on the nature of the sample.

File S4. This Excel file contains the U-Pb zircon data from LA-ICP-MS analyses in this study. Sample ZAP-13 is in sheet 1; samples ZAP-10, ZAP-11, and ZAP-14 are in sheet 2; samples ZAP-1, ZAP-3, ZAP-4, and ZAP-7 are in sheet 3. Column 1 consists of the individual spots, labelled first with the sample name and then the spot number that corresponds to the numbers included in the CL images in S5 (e.g., “ZAP10_3” is spot #3 in sample ZAP10). Other columns include ratios of 207Pb/235U, 206Pb/238U, and 207Pb/206Pb along with 2σ errors (labeled 2σ or Prop2SE) and error correlation between ratios (ρ or ErrorCorrelation); 207Pb-235U ages in Ma ±2σ, 206Pb-238U ages in Ma ±2σ, approximate U, Th, and Pb concentrations in ppm, and the U/Th ratio. For analytical details see section 3.2 in the manuscript.

File S5. This Excel file contains U-Pb data from apatite LA-ICP-MS analyses on sample ZAP-7, along with U-Pb data from standards of MAD and McClure Mountain apatite. Columns include ratios of 207Pb/235U (column G), 206Pb/238U (column J), 238U/206Pb (column N), and 207Pb/206Pb (column P), along with corresponding 2σ errors (labeled Prop2SE) and error correlation between ratios (“ErrorCorrelation”). For analytical details see section 3.2 in the manuscript.

File S6. This Excel file contains (U-Th)/He data for zircon crystals (sheet 1: “Zircons”) and apatite crystals (sheet 2: “Apatites”) from sample ZAP-7. This table follows the recommendations and approach in Flowers et al. (2022), and all columns are labeled and explained in the file. These data were collected at the Thermochronology Research and Instrumentation Laboratory at the University of Colorado Boulder (see Flowers et al., 2020 and Stanley & Flowers, 2020 for a description of laboratory techniques).
