The Negli Creek Limestone Member of the Kinkaid Formation (Logan, 1924, p. 11, 125; Malott, 1925, p. 112-114; Swann, 1963, p. 75).
Named for Negli Creek, Perry County, Indiana.
The type section of the Negli Creek Limestone Member is located along Negli Creek, Perry County, Indiana, in an exposure of 12 feet of limestone (NW 36, 6S-3W).
The Negli Creek Limestone Member is the lowermost member of the Kinkaid Formation.
The Negli Creek Limestone thickens southward from 16 feet in Effingham County to 37 feet in Franklin County.
In Illinois the Negli Creek Limestone Member is a massive limestone very similar in thickness and lithology to the Goreville Limestone Member but more extensive. Most of the limestone is brownish gray, but it has some light gray and brown beds. It is very fine grained but includes coarse grains of fossils. In places the lower part is lithographic. It is cherty, particularly in the upper part, but generally less cherty than the Goreville Member.
Algal growths (''Girvanella'') are common in the lower part of the Negli Creek, and large gastropods and small biserial Foraminifera occur near the middle.
