PhotosCassiterite - Guanajuato, Mexico

Cassiterite

Guanajuato, Mexico

Looks like goethite (or such iron oxyde)

Misidentified sample, or label swap?

To me, the broken edge looks very much like the cassiterite from various areas of the Black Range tin district here in New Mexico - streak & hardness should tell the tale.....

It's quite typical for the so-called "wood tin" variety of cassiterite from various parts of Mexico - Guanajuato, Durango...

Hi

Certainly looks like cassiterite to me. Quite nice in fact.

Could be from any number of localities in Mexico

Cheers

cassiterite has been nicknamed "the hardest of the heavy minerals" and "the heaviest of the hardest minerals", as hardness end density are both around 7: that will help distinguish it from ironoxides (also a different streak).

Looks like a very nice wood tin to me.

Unfortunately, there is no precise locality.
