Quartz eyes from different porphyry deposits were studied by electron probe microanalysis (EPMA) and hyperspectral cathodoluminescence (CL) mapping to determine their origin. These “eyes” are mm-sized crystals, which are commonly referred to as phenocrysts but in many cases may have formed after magma emplacement.
