Titanowodginite is an extremely rare member of the wodginite group, characterized by high titanium content. It is typically found in complex granite pegmatites and is primarily of interest to systematic mineral collectors due to its scarcity.

Is this titanowodginite?

5-step field check

Run through these checks against the specimen in your hand. The more boxes tick, the more confident the ID.

  • 1
    Test the hardness
    Try to scratch titanowodginite with a known reference. Titanowodginite sits at Mohs 5.5, softer than the next harder reference, harder than the previous one.
  • 2
    Check the streak
    Drag the specimen across an unglazed porcelain plate. Streak: dark brown.
  • 3
    Read the luster
    Hold the specimen under a strong light. Luster: vitreous.
  • 4
    Match the color range
    Compare against the expected color range: black, dark brown.
  • 5
    Look at form & habit
    Crystal system: monoclinic. Typical habit: euhedral crystals.

Where rockhounds find titanowodginite

Classic worldwide localities

  • Tanco pegmatite, Bernic Lake, Manitoba, Canada
  • San Piero in Campo, Elba, Italy

Field-hunting tip

Where it forms: In a complex zoned granite pegmatite (Tanco pegmatite, Canada). If you start seeing microlite, manganocolumbite, albite in float, you are in the right ground. Typical habit: euhedral crystals. Train your eye for that shape before scanning the outcrop.

Common questions

How do you identify titanowodginite?+
