Earth Science Minerals

 

First Group of Minerals have a Metallic Luster; Hematite is the exception because it can have either Metallic Luster or Non-Metallic Luster.

Galena

   Metallic

 

         

       

 

 

 

 

 

 

Magnetite

   Metallic

 

  

             

Note: Magnetite has a metallic luster. This mineral is magnetic, which means a magnet adheres to this mineral.  A magnet is the easiest way to determine if a mineral is magnetite.
