Oolite (egg stone) is sedimentary rock and although most ooids are formed from the collection of calcium carbonate, this is not always the case as these structures can be composed of phosphate, dolomite or even chert. 

Spalting is any color on wood caused by a fungus.  Colors caused by trees as a host response are not spalting.  Examples of things people often THINK are spalting, but are NOT, include boxelder (Manitoba maple, Acer negundo), the green streaks in hard maple and basswood, the purple in lilac, etc.  Blue stained pine is spalting, as is ambrosia maple, as fungi cause the coloring, although they are vectored into the wood by insects.
