[Rockhounds] Need help with Mineral ID

[Jim Murowchick]

    I agree with Stan--it looks like saddle dolomite typical of that found
in in the Tri-State District and elsewhere in southern Missouri and probably
into northern Arkansas.  It commonly has pyrite or marcasite on it and later
generation calcite.
