Naica: the slow growth behind giant gypsum crystals

## 1. Audit the source record

Retrieve the named records for Naica: the slow growth behind giant gypsum crystals. Record author, edition, page or section and access date. Treat a catalogue, mirror or translation of one document as the same evidence, not independent corroboration.

Status: proposed; not completed.
Evidence found:

Next action:

## 2. Build the dated evidence ledger

Extract temperatures, solutions, uncertainties and detection limits from the growth study. Compare them with independently measured fluid inclusions and mine-water conditions. Make assumptions explicit before estimating time, and show which variables make such an estimate uncertain.

## 3. Test the interpretation

Compare experimental rates and independently constrained formation conditions. Test proposed rates against mineral and fluid evidence. Record what would favour or weaken each explanation; leave unperformed work marked as proposed.
