Instrument view
Raw and processed values remain available together so preprocessing never replaces the original evidence.
Instrumental characterization and source compatibility
Chert Instrumental Analysis Explorer
A geographic source explorer linked to a separate multimethod analysis workspace. Browse locally installed specimen populations first, inspect satellite context, spectral envelopes, and validation results, then load the selected source directly into instrument-specific comparison.

Geographic source explorerData-derived source populations, generalized locality anchors, and separate archaeological-site records
Initializing local source data...
Spatial evidence policy: geological sources, archaeological find sites, and analytical-only populations are distinct record classes. Map anchors are generalized and carry an uncertainty value; the explorer does not expose precise sensitive collection coordinates or fabricate locations for unresolved populations.
Transparent analytical layers
Analytical Outputs
Feature view
Peaks, bands, elemental variables, missing values, and quality-control flags are displayed as inspectable records.
Comparison view
Similarity or classification is calculated only within compatible method families and documented transformations.
Concordance view
Multiple methods are reported as agreeing, conflicting, or absent rather than averaged into a false certainty.
Validated local references
Reference Library and Academic Provenance
Original repository files are preserved in a protected, same-origin source archive. Only separately normalized and runtime-validated bundles are exposed to the browser. GitHub, ScienceBase, tDAR, and other repositories are read-only acquisition points; they are never publication targets.
Loading local registry and validating bundle checksums.
Reproducible intake
Reference Validation Pipeline
The Parish spectral workbooks, full USGS ASCII archive, RockSL archive, and fifteen MURR chert studies reside locally. The unified registry exposes 261 analytical populations: 115 geological-source populations, 101 archaeological-artifact populations, and 45 unresolved or control groups. Eighty-four records have documented generalized map anchors; unmapped populations remain analysis-ready without invented coordinates.
Acquire
Read-only download or repository-mediated manual intake. Floating branches are rejected by the synchronizer.
Preserve
Original files remain in local source storage with exact SHA-256 values and academic citation metadata.
Adapt
Method-specific adapters convert Parish spectra, reviewed MURR INAA tables, USGS ASCII, and RockSL records while preserving instrument family, specimen role, and study provenance.
Validate
Schema, record length, specimen role, method family, archive receipt, population checksum, and canonical specimen identity must pass before browser loading.
Constrain
Technical mineral references cannot be silently promoted into geological provenance source groups.
Activate
Only registered normalized bundles are exposed to the browser; original archives remain server-protected.
Normalized bundle validation
Installed-bundle validation will appear here.

Review before interpretation
Methodological Note
The note documents parser assumptions, preprocessing options, compatibility language, reference-library requirements, and the separation between characterization and provenance inference.

Scholarly Annotations and Peer Review
Use this record to propose a source-code identification, submit a citation, report a reproducibility issue, or question an analytical interpretation. Submissions are stored locally and displayed as community commentary; they do not alter the validated dataset or analytical results.
Research Community Annotation Log
Newest submissions appear first. Each entry remains explicitly labeled as unreviewed unless editorial review is added later.
