Field-hunting tip
Look in alkaline pegmatites country — that is the host setting where ivanyukite-na typically forms. If you start seeing natrolite, aegirine, titanite in float, you are in the right ground. Field specimens usually show a prismatic to tabular crystals habit, so train your eye for that shape before scanning the outcrop.
