Structural Analysis — Sheet 01
The first structural worksheet combines field photographs, traced discontinuities and a stereographic plot, creating a useful chain from exposure to orientation analysis. The principal audit question is whether every plotted plane and line corresponds to a traceable measurement rather than an interpretive line drawn after the fact.

Geological interpretation and evidential boundary
The first structural worksheet combines field photographs, traced discontinuities and a stereographic plot, creating a useful chain from exposure to orientation analysis. The principal audit question is whether every plotted plane and line corresponds to a traceable measurement rather than an interpretive line drawn after the fact. Orientation convention, hemisphere, sample count and the distinction between bedding, joint, fault plane and slickenside must be explicit. Cluster density can reveal preferred fabrics, but weathering surfaces and repeated readings from one exposure can artificially tighten a mode. This sheet is strongest as provenance for the structural dataset; kinematic conclusions require independent shear-sense evidence and map-scale continuity.
