Springcreekite is a rare phosphate mineral from the plumbogummite group, typically occurring as small crystals or crusts within weathered phosphate-rich environments. It is most famous for being found in the Spring Creek area of Queensland, where it forms in association with other iron and phosphate minerals.

Is this springcreekite?

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

Field-hunting tip

Look in weathered phosphate deposits country — that is the host setting where springcreekite typically forms. If you start seeing quartz, goethite, hematite in float, you are in the right ground. Field specimens usually show a crusts and minute crystals habit, so train your eye for that shape before scanning the outcrop.
