Geological Fact of the Month - February

Here is our geological fact of the month for February. Enjoy.

You can check out all of the geological facts (Geoacts) by going to the Geoacts page.


  1. We typically encounter water as liquid or vapor at the Earth's surface (save for the poles). So in that environment it's not really a mineral, but on the moon, mars, on comets - it's as much a mineral as the olivine and iron and nickel. My students always get a kick out of that.

  2. Yes, exactly. I remember when I took glaciology that that is the primary instance where it was referred to as a mineral.
