Colin, a good friend of Graeme and I, spoke about the strength of relationships and connections particularly across communities and how we need to work harder to understand crosscutting relationships
to build community cohesion through social capital.
Veins crosscutting relationships were first determined in the field, and several samples were taken of each vein generation (Groups I, II, and III).
Thin-section petrography confirmed the crosscutting relationships established during field observations.
Several pulses of fluid flow were identified based on the crosscutting relationships, as confirmed by the petrographical analyses.
Crosscutting relationships with calcite sparitic cement (Vein Group II) show that the impurities-rich fringes predate vein cementation.
In Selwicks Bay, crosscutting relationships demonstrated that the tilting essentially occurred between Group I and Group II veins.
The former sampling has been focused on fractures from centimetres to few meters length, recording orientation (azimuth and dip), aperture (mm), length (cm), distance from the origin (cm), morphology, filling, and crosscutting relationships. Scan lines have been performed on six beds, with a cumulative length of 20 meters along the outcrop surface.
Joints length (cm), aperture (mm), distance from the origin (cm), azimuth, dip, morphology, crosscutting relationships, and filling have been collected.
