Field-hunting tip

Look in granite pegmatites country — that is the host setting where zinconigerite-6n6s typically forms. If you start seeing sillimanite, cassiterite, gahnite in float, you are in the right ground. Field specimens usually show a tabular hexagonal crystals habit, so train your eye for that shape before scanning the outcrop.
