Age:Mississippian Type designation:
Type locality: The name "Aux Vases Sandstone" was given to sandstone exposed in the bluffs at the mouth of the Aux Vases River in Ste. Genevieve County, Missouri, by Keyes (1892, p. 296) (Gray, 1986, p. 6). History of usage:Extended: The name “Aux Vases Sandstone” was applied to the Indiana outcrop by Malott (1945, 1946, 1952) (Shaver, 1970; Gray, 1986). Revised: The name “Aux Vases Formation” as used by Malott was reject for use in Indiana by Gray, Jenkins, and Weidman, (1960, p. 49). They (1960, p. 50) proposed that strata formerly designated as Aux Vases be regarded as the basal unit of the Paoli Limestone. The name “Aux Vases Formation” was retained for rocks called Aux Vases or basin Aux Vases by Pinsak (1957, p. 19, 22) and Swann (1963, p. 18-19, 29, 30) in their subsurface work in southwestern Indiana (Shaver, 1970). Restricted: Droste and Carpenter (1990) reduced the rank of the Aux Vases to that of a member and restricted the Aux Vases Member to the shales and sandstones that lie between the interbedded carbonate rocks, shales, and sandstones of the uppermost part of the Ste. Genevieve Limestone below and the Renault Member of the Paoli Limestone above. Description:In Indiana the Aux Vases Member is composed of green to greenish-gray calcareous and variably fossiliferous shale interbedded with lenses of shaly to pure, very fine grained sandstone. In a few places in the subsurface there is a small amount of red to maroon in the gray and green shales (Droste and Carpenter, 1990). The shales contain small carbonate nodules and thin and discontinuous lenses of limestone. The Aux Vases Member ranges from less that 1 ft (0.3 m) to more than 30 ft (9 m) in thickness; however, throughout most of the subsurface in Indiana the Aux Vases is less than 10 ft (3 m) thick (Droste and Carpenter, 1990). Its maximum thickness is 38 ft (11.6 m) in Posey County (Droste and Carpenter, 1990). Distribution: In Indiana the Aux Vases Member of the Paoli Limestone extends from Owen County southwestward to Posey County (Droste and Carpenter, 1990, fig. 21). Boundaries:The contact between the Aux Vases Member of the Paoli Limestone and the underlying Ste. Genevieve Limestone is conformable generally, but in some places near the outcrop the contact may be one of minor discontinuity (Droste and Carpenter, 1990). Correlations:Droste and Carpenter (1990) traced the Aux Vases from the subsurface to surface exposures; in the outcrop area the Aux Vases interval was previously recognized as the Popcorn Member at the base of the Paoli Limestone. They (1990, fig. 2) assigned the Aux Vases Formation to the uppermost part of the Valmeyerian Series and the lowermost part of the Chesterian Series.

Misc/Abandoned Names:Popcorn Member Geologic Map Unit Designation:Mpav 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 terminologyNames 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.
