Allostratigraphy: Tippecanoe Sequence

Name Origin

The Tippecanoe Sequence (Sloss et al., 1949, p. 115) is named for Tippecanoe County, Indiana.

Stratigraphic Position

The Tippecanoe Sequence consists of the strata overlying the Sauk Sequence and underlying the Kaskaskia Sequence (fig. 14). In Illinois the base of the sequence is at the sub-St. Peter--Everton (sub-Champlainian) unconformity (fig. O-13), and the top is bounded by the sub-Dutch Creek--Wapsipinicon (sub-Middle Devonian) unconformity (fig. D-7). It, therefore, includes strata of middle to late Ordovician, Silurian, and early Devonian age. Although minor or local unconformities occur within the sequence, its formations have a similar tectonic environment and are generally parallel throughout the state. They overlap the more deformed Sauk Sequence, and, in turn, were deformed and partly truncated before they were overlapped by the Kaskaskia Sequence.
