Zhangpeishanite is an exceptionally rare barium fluoride chloride mineral found primarily in the Bayan Obo rare-earth deposit. It typically occurs as small tabular crystals associated with other rare fluorides and barite. Collectors usually encounter it as microscopic inclusions or tiny crystals within matrix material.

Is this zhangpeishanite?

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 zhangpeishanite with a known reference. Zhangpeishanite sits at Mohs 2.5 — softer than the next harder reference, harder than the previous one.
  • 2
    Check the streak
    Drag the specimen across an unglazed porcelain plate. Zhangpeishanite leaves a white streak.
  • 3
    Read the luster
    Hold the specimen under a strong light. Zhangpeishanite typically shows a vitreous luster.
  • 4
    Match the color range
    Compare against the expected color range: colorless, white.
  • 5
    Look at form & habit
    Crystal system: trigonal. Typical habit: tabular crystals.

Where rockhounds find zhangpeishanite

Classic worldwide localities

  • Bayan Obo, Inner Mongolia, China

Field-hunting tip

Look in hydrothermal veins in rare-earth element deposits country — that is the host setting where zhangpeishanite typically forms. If you start seeing baryte, fluorite, quartz in float, you are in the right ground. Field specimens usually show a tabular crystals habit, so train your eye for that shape before scanning the outcrop.
