Wolff Hofstra University INTRODUCTION While studying the clay mineralogy and trace element dis tribution of shales within the Marcellus Formation in south eastern New York for the purpose of pale©environmental analysis and interpretation, it became apparent that the persistence of certain "reworked" shoreline lithosomes could provide an addi tional basis for correlation and environmental interpretation (Wolff,1967a). These rock units, occurring within the suggested time-strat igraphic units of Cooper (1933) and Goldring (1943) were found in the uppermost 150 feet of the Marcellus Formation between the Schoharie Valley and Port Jervis, New York (Figure 1).
