Text Description: A silicic dike, trending N135°E forming a wall-like, platy outcrop on the south-west end of Tanada Lake. Fine grained, holocrystalline, porphyritic with a matrix of feldspar, opaque, amphibole? or biotite?, and a small high relief mineral. Plagioclase phenocrysts are up to 3.62 mm, and are frequently rounded; some have oscillatory zoning. Clinopyroxene phenocrysts are up to 1.2 mm and tend to have brown/opaque rims. Opaque phenocrysts are up to 0.25 mm. References: ![]() |
