The Upper Ordovician section consists of interbedded fossiliferous limestone or dolomite and shale; shale dominates some parts of the section, and limestone or dolomite other parts. Both the Lexington Limestone and the Upper Ordovician rocks were deposited in tropical latitudes in shallow marine water on a shelf that sloped gently northward.Siltstone is deposited in a similar environment with shale, but is usually located near the old delta, lake or sea shore, where calm currents cause less particle suspension. Siltstone is generally formed adjacent to sandstone deposits – ie close to beaches and delta edges where sand is deposited.Siltstone is deposited in a similar environment with shale, but is usually located near the old delta, lake or sea shore, where calm currents cause less particle suspension.
