Type locality: Named by Kindle (1899, p. 8) for Jeffersonville, Clark County, Indiana, where the formation is well exposed during low-water stages at the Falls of the Ohio.
History of usage:
Overview: The descriptive term “Corniferous Limestone” was used by Borden in 1874 for Jeffersonville rocks, but "Corniferous" has also been used in Indiana to refer to the entire Muscatatuck Group (Middle Devonian) (Droste and Shaver, 1986). The term "Corniferous" in both senses has been abandoned (Droste and Shaver, 1986).
Many geologists and lay persons have provided accounts of the Jeffersonville at the Falls of the Ohio (that is, at the type locality) especially because of the prolific corals and the remarkable fossil community that they and other fossils represent (Droste and Shaver, 1986). The rocks here have generally been described in terms of three to six biozones (for example, Burger and Patton, 1970, p. 77, three zones; Powell, 1970, four zones; and Oliver, 1976, p. 19, six zones) (Droste and Shaver, 1986). In Perkins's (1963) terms the type Jeffersonville consists in ascending order of (1) mostly brown coarse-grained medium- to thick-bedded, highly fossiliferous limestone and dolomitic limestone (Coral Zone =? Lower and Upper Coral Zones of Oliver, 1968), (2) variably colored coarse-grained medium-bedded stromatoporoidal limestone (Amphipora Zone), (3) variably colored dense to medium-grained cherty hard fossiliferous limestone (Brevispirifer gregarious Zone), and (4 and 5) light-colored thin-bedded to massive granular cherty fossiliferous limestone (Bryozoan-Brachiopod Zone below and Paraspirifer acuminates Zone above) (Droste and Shaver, 1986).
The Jeffersonville overlies the New Harmony Group (Lower Devonian) both conformably and unconformably in the far southwestern Indiana counties, and elsewhere in its Indiana distribution it unconformably overlies Lower to Upper Silurian rocks ranging stratigraphically from the Salamonie Dolomite (Laurel Member) upward to the upper part of the Wabash Formation (Droste and Shaver, 1986). This is an erosionally truncating relationship, the amount of truncation increasing eastward from the Illinois Basin and southeastward along the area of outcrop (Droste and Shaver, 1986). The Jeffersonville is overlain by the North Vernon Limestone, possibly everywhere unconformably (Droste and Shaver, 1986).
The Jeffersonville has traditionally been correlated with the Onondaga Formation (Erian) of New York on the basis of its macrofossils (Droste and Shaver, 1986). During more recent time, correlation has been facilitated by many studies of Middle Devonian conodonts in North America and Europe and by widespread recognition of the Tioga Bentonite Bed (Droste and Shaver, 1986). A lower, non-Geneva part of the Jeffersonville was assigned to the Icriodus latericrescens robustus Zone before Dutch Creek and Geneva rocks were added to the Jeffersonville, whereas upper Jeffersonville rocks were assigned to the Icriodus augustus Zone (Droste and Shaver, 1986). This zone extends stratigraphically upward to include lower North Vernon rocks (Droste and Shaver, 1986). (See Orr, 1971, p. 16-17, for these conodont-zonal assignments.) These determinations show that the Jeffersonville is largely Eifelian (global standard) in age, and a lower part is probably as old as late Emsian, a possibility that is also suggested from the work of Conkin and Conkin (1979, p. 14), Wright (1980, p. 5-7), and Sparling (1983, fig. 9) (Droste and Shaver, 1986). (See also Rickard, 1975, pl. 3; Oliver, 1976; Klapper and Ziegler, 1979; and Shaver, 1984.) Close to approximate correlatives of the Indiana Jeffersonville include the Grand Tower Limestone, southern Illinois; the Detroit River Formation, northern Indiana and western Ohio; the Lucas Formation and possibly the upper parts of the Amherstburg Formation and the Sylvania Sandstone, southern Michigan; the Columbus Limestone and the lower part of the Dundee Limestone, central to northwestern Ohio; the Onondaga Formation, New York; and the Jeffersonville Limestone, western Kentucky (Droste and Shaver, 1986).

Geologic Map Unit Designation:
Note: Hansen (1991, p. 52) in Suggestions to authors of the reports of the United States Geological Survey noted that letter symbols for map units are considered to be unique to each geologic map and that adjacent maps do not necessarily need to use the same symbols for the same map unit. Therefore, map unit abbreviations in the Indiana Geologic Names Information System should be regarded simply as recommendations.
COSUNA areas and regional terminology
Names for geologic units vary across Indiana. The Midwestern Basin and Arches Region COSUNA chart (Shaver, 1984) was developed to strategically document such variations in terminology. The geologic map (below left) is derived from this chart and provides an index to the five defined COSUNA regions in Indiana. The regions are generally based on regional bedrock outcrop patterns and major structural features in Indiana.
