Key Concepts<\/h3>\n

Alteration Minerals:<\/b> Epidote, Chlorite, Actinolite, Sericite, Tourmaline, Albite, Clay, Tremolite, Calcite<\/p>\n

Kalb Hardness Test:<\/b> The Kalb line light, in optical mineralogy is a test made on polishing relief, which is very similar to Becke Line test. Microscope focused clearly on the boundary between two minerals grains. Microscope is raised (stage lowered) and as the specimen begins to go out of focus, a “line of light” will move towards the softer mineral (due to differing mineral properties).<\/p>\n

Paragenetic Sequence:<\/b> if a mineral is on top on within another mineral, the one on top or within it likely formed first. More euhedral minerals usually form first as well.<\/p>\n

Disseminated:<\/b> Sulfide droplets remain suspended in magma flow.<\/p>\n

Net-textured:<\/b> likely through dynamic flow segregation.<\/p>\n

Massive:<\/b> sulfides settle at the bottom of the magma chamber; because of their heavy nature.<\/p>\n

Tectonic deformation:<\/b> fracture sulfides in fold hinges, thickening in hinges, concentric folds, small scale faults, fractures, brecciation.<\/p>\n

Soft-Sediment deformation:<\/b> slumping, smearing, folding, dish and pillar, ball and pillow, convolute bedding, fluid escape, disharmonic folds.<\/p>\n

Diatreme:<\/b> higher, breccia-filled volcanic pipes formed by gaseous explosions. More country rock.<\/p>\n

Hypabyssal:<\/b> lower, igneous rocks are usually fine or medium-grained rocks, however, large phenocrysts often occur within rocks termed porphyrys. No country rock.<\/p>\n
