Description:	A correlation diagram of lithostratigraphic units of Pennsylvania shown within a chronostratigraphic framework of North American and “global” subdivisions. The chart has 15 columns representing 15 areas in Pennsylvania. Rock units in Pennsylvania range in age from Precambrian through Quaternary, and all periods of the Phanerozoic Eon are represented. The publication includes an extensive reference list (almost 300 references). The chart was first published in 1983 and was reprinted with revisions in 1986 and 1993. It is the third printing that is represented here, and it includes a two-page addendum (an annotated bibliography for the latest round of revisions). Contact information at the top of the addendum was updated on the scanned image.
