REVISION OF SOME STRATIGRAPHIC NAMES BETWEEN THE LOWER AND MIDDLE KITTANNING COALS IN EASTERN OHIO

Recent observations on the strata between the Lower and Middle Kittanning Coals in eastern Ohio indicate that some additions and corrections in stratigraphic names are in order. Modifications pertain not only to beds associated with the Kittanning Coals but also to those in the intervening Strasburg cyclothem. Certain of these changes have already been noted (Sturgeon and associates, 1958: 64, 66) \ but revisions there proposed are not valid under the provisions of the Code of Stratigraphic Nomenclature (1961: 653, Art. II). Sturgeon and others are preparing a detailed report, but it will not be concluded soon enough to permit use of the revised nomenclature in certain publications of the Ohio Division of Geological Survey that are nearing completion and in which these names should be included. This note is to validate these new and revised names, so that they will be available for use in the Survey's forthcoming publications. The current use of stratigraphic names by the Ohio Division of Geological Survey for the section under consideration is that standarized by Stout and pub-lished by Bownocker and Dean in 1929 and employed in numerous subsequen
