Public catalogue of accessioned mineral and material samples

Anonymous submissions; provenance of specimens not asserted beyond what is filed at intake.

Each listing describes a real specimen or fraction that passed intake: names, chemistry, crystal system, locality as reported, and — where completed — summary spectroscopic and physical results under the limits stated in the methodology. The layout looks dull on purpose; the goal is stable citation and corrections on paper, not advertising copy.

Why this touches the same topic as verifiable systems. Publishing a table online is trivial; showing later that nobody secretly re-ordered or rewrote the rows is harder. This registry chains records with published SHA-256 links so a third party can recompute the sequence (see the proof-chain section and verification tool). That addresses the same kind of problem distributed ledgers were invented for — agreement on an ordered log — except the payload is mineralogical metadata and lab notes, not account balances. There is no asset or instrument here; the only parallel is an independently auditable archive.

Run without profit; submissions are reviewed before publication. Nothing here is an offer of goods, securities, or services.

What appears in the index

Four kinds of material—pick what you need to cite or to audit.

  • Description. Name, formula, habit, colour, locality, classification — stored as filed, changed only through published errata.
  • Laboratory fields. Raman peaks and related notes match the accession suffix (how far review has run). Uncertain rows are labelled; see classifications and rules.
  • Integrity of the list. Each row carries a hash tied to the previous one so you can check order yourself — how it is built, try the checker.
  • Official correspondence. Withdrawals, supersessions, bulletins, annual gazettes — so a citation dated 2016 can be reconciled with a correction issued later.

registry snapshot

The catalogue lists 386 accessioned records and accepts new submissions through the standard intake path (reviewed by hand). Identifiers use AM-YYYY-NNNNN-X, where the trailing letter marks how far analytical review has progressed (see methodology). Browse by property filters, consult the open-data exports, or read the cataloguing rules if you need the full procedural spine.

about this site

The registry has no formal institutional affiliation. Operating costs are met through small private donations. Contributors who wish to remain anonymous may use the standard submission pathway; identifying information, when supplied, is stored separately from the public record and is not redistributed.

For questions concerning a specific record, cite the full accession identifier (including the pass-letter suffix) in any correspondence. See about the registry.
