Table T3. Checklist used for spreadsheet com-ments associated with each structural identifier.
| The following is a checklist of structural characteristics that were searched for in macroscopic core samples. These characteristics supplement the information required by the spreadsheet and were noted in the comments section of the spreadsheet. The abbreviations for these features were used to document crosscutting relationships (where > indicates "older than") on the structure section of the VCDs. |
| Subhorizontal microcracks (Shm) |
| Drilling-induced fractures |
| Join ts (J) |
| Joint density |
| Orientation |
| Plume structures on joint surface |
| Veins (V) |
| Orientation of veins and vein-array boundaries |
| Magnitude and nature of offset |
| Density of vein network |
| Array characteristics |
| Sense of shear |
| Angle between new vein segments and array boundary (measure of array dilatation) |
| Internal structure of fibers |
| Crack-seal structures and number of vein-opening events |
| Wall-rock alteration and shape |
| Vein terminations (splayed or tapered) |

| Inter-limb angle |
| Estimate of hinge curvature (e.g., kink vs. round) |
| Asymmetry of hingeline relative to other fabrics (e.g., stretching lineations, etc.) |

| Number of folds, if more than one |
| Crystal-Plastic Fabrics (Pf) |
| Intensity of fabric |
| Intensity of fabric in retrograde assemblage |

| Mineralogical segregation or banding |
| Magmatic Fabrics (Mf) |
| Intensity and orientation of foliations (Sm) and lineations (Lm) |
| Minerals that define the shape and/or crystallographic preferred orientations |
| Angle between crystallographic and shape fabrics |
