Womble Shale
Open-knowledge reference entry
The Womble Shale is a Middle Ordovician geologic formation in the Ouachita Mountains of Arkansas and Oklahoma. First described in 1892, this unit was not named until 1909 by Albert Homer Purdue in his study of the Ouachita Mountains of Arkansas, where he named this unit as part of the upper Ouachita Shale and the Stringtown Shale. In 1918, U.S. Geological Survey geologist, Hugh Dinsmore Miser, replaced Purdue's nomenclature with the Womble Shale. Miser assigned the town of Womble (now called Norman) in Montgomery County, Arkansas as the type locality. As of 2017, a reference section for this unit has yet to be designated.
Begin with the source’s own compact description: “Womble Shale” is open-knowledge reference entry. The dossier treats that line as a proposition to test through Womble, Shale and Open-knowledge, not as a finished interpretation.
Why this record matters
The phrase “open-knowledge reference entry” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jan 18, 2026. The linked authority identifier is Q48971452. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1892, 1909, 1918 and 2017.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
