Hydrothermal Gold

This secondary electron image pictures several grains of hydrothermally grown gold (gold coloured particles) resting on silver chloride (blue). These crystals were grown by Dr. Chris Gammons of McGill EPS as part of a series of experiments in gold-silver solubility at low temperatures. Although the crystals appear to have a pentagonal symmetry, they are actually orthagonal, the pentagonal shapes due to twinning
