Marchettiite is an organic ammonium hydrogen urate formed by circulation of meteoric waters at low temperatures, and enriched with soluble altered biological material. This mineral is essentially a molecule of ammonia combined with a molecule of uric acid, with biological origins that can be traced to the urine or feces of a bird or other animal.
