Kanemite is a rare hydrated sodium silicate mineral primarily found in evaporitic alkaline lake deposits. It typically forms delicate, white, platy, or micaceous aggregates that are easily dehydrated upon exposure to air.

Is this kanemite?

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

Field-hunting tip

Look in alkaline lake sediments country — that is the host setting where kanemite typically forms. If you start seeing magadiite, quartz, calcite in float, you are in the right ground. Field specimens usually show a platy crystals habit, so train your eye for that shape before scanning the outcrop.

Common questions

How do you identify kanemite?+

Mohs hardness is 2. It typically shows a pearly luster. The streak is white. Common colors include white, colorless.

Where is kanemite found?+

Notable localities include Lake Chad, Chad; Searles Lake, USA; Soda Lake, USA.

Typical asking prices fall in the range of $20-100 thumbnail. Quality, size, and provenance can move individual specimens well outside that range.

What rocks look like kanemite?+

Kanemite is most often confused with Magadiite, Kenyaite. A quick hardness test and a streak check separate the look-alikes faster than color alone.

What minerals are found with kanemite?+

Kanemite commonly co-occurs with Magadiite, Quartz, Calcite. Spotting any of these in float or country rock is a useful trip signal.

What kind of rock does kanemite form in?+

Kanemite typically forms in alkaline lake sediments. Working float back to the host body is the standard way to chase a fresh occurrence.
