Web2.2.3 Fluid pathways. In the porphyry-epithermal mineral system, pathways for fluids and their contained metals, ligands and sulfur include faults, stratigraphic aquifers and crystallising intrusive bodies. Crystallising … Porphyry is the name given to decorative granites or igneous rocks with coarse-grained crystals such as feldspar or quartz dispersed in a fine-grained silicate-rich, generally aphanitic matrix or groundmass. The larger crystals are called phenocrysts. In its non-geologic, traditional use, the term porphyry usually refers to the purple-red form of this stone, valued for its appearance, but other colour…
