geognosy

Source-qualified definition

Definitions must retain their scope and attribution. Webster's 1828 entry describes Earth's structure while also recording disagreement over the relationship to geology. [Webster's 1828 entry](https://webstersdictionary1828.com/Dictionary/geognosy).

1. What does the selected source explicitly include under geognosy? definition
2. Which author, date, language and edition establish this meaning? provenance

Geology and mineralogy boundaries

Record whether a source treats geognosy as geology, a component of it, or a differently bounded inquiry, and how it separates rock relationships from mineral identification.

1. How does this source distinguish geognosy from geology and mineralogy? boundary
2. Does an existing catalogue model cover the same concept under this definition? action

Mineral-rock associations

Lyell's historical account characterises Werner's geognosy through mineral positions within rocks, rock grouping, distribution and relationships. Preserve these relations when identifying its subject matter. [Lyell's account](https://sourcebooks.web.fordham.edu/mod/lyel-geology3-4.asp).

1. Which relationships between minerals and enclosing rocks does the account investigate? definition
2. Which observations support the stated association at a particular locality? provenance

Rock-body order

Record reported adjacency, superposition and distribution separately from claims that bodies are continuous, equivalent or chronologically ordered.

1. Which contacts or positions were observed, and which were inferred? provenance
2. Does the stated order describe physical position, relative age or a theoretical sequence? boundary

Exposure and section support

For evidence used by an account, preserve locality, observation setting, recorded dimensions and gaps in visibility; do not assume every historical study used the same methods.

1. Was the description based on an outcrop, mine working, collected specimen or another observer's report? provenance
2. What thicknesses, orientations or distances were recorded, with which original units? measurement

Correlation warrant

A proposed correspondence between separated rock occurrences needs its stated comparison criteria and acknowledged observational gaps.

1. Which observed similarities or positional relationships justify correlating the occurrences? provenance
2. What additional evidence would be needed before extending the correlation beyond the surveyed area? action

Formation-term semantics

Treat formation names and rock classes as terms within a specified author's system until their relationship to modern terminology is demonstrated.

1. What makes a rock body belong to this class in the cited system? definition
2. Does the historical term formation identify the same kind of unit as a proposed modern equivalent? boundary

Theoretical dependence

Assess each claim's dependence on an origin theory rather than equating geognosy with a single doctrine or rejecting an observation because its explanation is outdated.

1. Which conclusions depend on a theory of rock formation rather than recorded arrangement? boundary
2. What explicit passage supports attribution to a named theoretical school? provenance
3. Which observations remain usable if that explanation is set aside? action

Documented field status

Record dated uses in course titles, manuals, institutional records or learned publications without presuming an independent degree, journal or society existed.

1. Which dated teaching or publication records explicitly name geognosy as a field? provenance
2. Does the record establish a disciplinary unit, a course topic or only a word in a title? boundary

Supported modern placement

Any DDC, UDC or other classification mapping must identify the scheme, edition and supporting entry; related modern subjects are candidate mappings until equivalence is checked.

1. Which classification edition explicitly indexes geognosy, and under what heading or code? provenance
2. Is the relationship to the proposed modern field equivalence, narrower scope or partial overlap? boundary
3. Should the registry link to an existing model or retain a distinct historical concept based on this evidence? action
