Abstract

In recapitulation: Taxonomic analysis of the problem of the Galena limestone shows that, (1) In concept here is a last, lingering relict of Wernerian geology of the Eighteenth century; (2) Galena limestone is not a good geological formation, but a lithologic facies of another; (3) Its title is untutored miners' parlance instead of a scientific derivation; (4) Its name is not taken from some geographic one, but town of this name takes title from the rock; (5) It is not the equivalent of the Carbonic Galeniferous limestone of England as so long regarded ; (6) United to the Blue limestone from which it is really derived, it forms part of a valid stratigraphic unit and terrane; (7) An alteration product, its usual lithologic designation is a misnomer; (8) By itself it is wholly devoid of the common attributes essential to terranal definition; (9) It is not bounded above and below by sedimental unconformities as sometimes claimed; and, (10) Synonymic analysis decrees it to be a northward extension of the McCune limestone of Missouri.
