They are composed of the iron sulfide mineral pyrite. This growth form is commonly known as a pyrite sun.

Pyrite suns are found in many different geological settings but probably the most familiar are the pyrite suns found in coal mines. Illinois is particularly proud of these being commonly found there.
 

Welcome, Shep, to the forum from Oregon! Thanks Clay, for the identification! The knowledge on this forum is astounding!
