Teneriffe Silt (Willman and Frye 1970).
Derivation
The Teneriffe Silt is herein named for Teneriffe School, 2.5 miles northeast of New Salem, Pike County.

History/background
Type section
Type location
The type section is the New Salem Northeast Section (table 6), described from roadcuts three quarters of a mile southwest of Teneriffe School, NW NE SW Sec. 11, T. 4 S., R. 4 W. It is classified as a formation.
Table 6 -- Stratigraphic Sections (partial) The following 21 stratigraphic sections describe exposures in Illinois and illustrate many of the aspects of Pleistocene stratigraphy. These sections contain the type localities for 21 rock-stratigraphic units, 4 soil-stratigraphic units, and 3 time-stratigraphic units and include paratypes for several other units. The sample numbers preceded by "P" are the numbers used in the Illinois State Geological Survey collections. Analytical data on many of these samples are on file at the Survey. The sections are arrange alphabetically by name. |

Stratigraphic relationships
In the type area it rests on the Pike Soil developed in Kellerville Till (Liman Substage of Illinoian Stage), and its upper boundary is the top of the Sangamon Soil, developed in the silts; it is overlain by the Roxana Silt. The term is not used beyond the limit of Illinoian glaciation, as beyond this limit comparable deposits are included within the Loveland Silt (fig. 7).
Extent and thickness
Lithology
The Teneriffe is largely silt, but it contains beds of sand and clay. It is generally leached, because it contains the Sangamon Soil in the top, but it is calcareous in the lower part at a few places where it is thick (e.g., the Pleasant Grove Section, table 6). It is massive and ranges from gray to tan-brown.

Age and correlation
The Teneriffe Silt includes deposits that range from latest Liman Substage through the Monican and Jubileean Substages of the Illinoian Stage. It may contain both retreating and advancing outwash of the Illinoian glaciers, as well as sheetwash and some eolian deposits.
