serpentinization-hosted carbonate hydrothermal vent chimney

habitatmech:GOLD.1208484062 ·AQUATIC ·UNGROUNDED REVIEWED

A marine hydrothermal vent chimney which is built of brucite and calcium and magnesium carbonates precipitated where low-temperature, hyperalkaline, hydrogen- and methane-rich fluid produced by serpentinization of ultramafic rock mixes with seawater. — HabitatMech

Curation

What a curator decided about this record, and why. A record built from several source concepts can carry one decision per concept.

1. CONFIRM_UNGROUNDED 2026-09-08 · codex-gpt-5

   Confirmed UNGROUNDED: no ontology term fits this concept. ENVO:01000053 'marine ultramafic hydrothermal vent biome' kept as an xref. Definition research for Carbonate traced the inspected GOLD organism rows to Prony Hydrothermal Field carbonate chimneys, not to soda-lake water or to carbonate ion as a habitat. The leaf denotes a serpentinization-hosted brucite/carbonate hydrothermal chimney; ENVO:01000129 is the term-request genus, ENVO:01000053 is related ultramafic vent context rather than an identity or parent, and alkaline-water and carbonate-chemistry terms describe the venting fluid or its chemistry rather than the sampled chimney. GOLD's Non-marine Saline and Alkaline placement is a source classification artifact here because the chimneys stand in shallow marine and intertidal settings.

2. DEFINED 2026-09-08 · codex-gpt-5

   Defined as 'serpentinization-hosted carbonate hydrothermal vent chimney' under ENVO:01000129 'marine hydrothermal vent chimney'. Definition authored from a Carbonate evidence review. The review checked ten of the twelve current organism assertions against the 2021 GOLD export and isolate descriptions, found only Prony Hydrothermal Field carbonate-chimney isolates, and concluded that GOLD's bare Carbonate leaf denotes a serpentinization-driven carbonate chimney rather than carbonate-rich soda-lake water. ENVO:01000129 'marine hydrothermal vent chimney' is the tightest vendored genus because existing alkaline-water, microbialite, carbonate-rock and smoker terms describe the wrong material, process or vent type. parent_mode=REPLACE intentionally drops the inherited Alkaline parent because it is marked NOT_APPLICABLE and because this leaf is marine or intertidal despite GOLD's Non-marine bucket. Two organism rows added after the local 2021 GOLD export remain unchecked because live GOLD fetches returned 403.
