Dawsonite - Wikipedia
WEBDawsonite is a mineral composed of sodium aluminium carbonate hydroxide, chemical formula NaAlCO 3 (OH) 2. It crystallizes in the orthorhombic crystal system. It is not mined for ore.

WEBdawsonite, a carbonate mineral, NaAlCO 3 (OH) 2, that is probably formed by the decomposition of aluminous silicates. Of low-temperature, hydrothermal origin, it occurs in Montreal, where it was first discovered; near Monte Amiata, Tuscany, Italy; and in Algiers.
Dawsonite - an overview | ScienceDirect Topics
WEBDawsonite is an hydroxycarbonate of sodium and aluminium [NaAl (CO3 ) (OH) 2] named in 1874 after the Canadian geologist J.W. Dawson (1820−1899). Both K + and NH 4 ions are able to substitute for Na + ion in dawsonite ( Zhang et al., 2004 ). However, Na-rich compositions are most common in nature.

WEBApr 1, 2022 · Dowsonite, as the main carbon-fixing mineral, is an orthorhombic carbonate mineral containing water, sodium and aluminum. The carbon capture of dawsonite in the reservoir rocks accounts for 42.2%-90.1% of the total carbon sequestration. Dawsonite is widely distributed across the globe, especially in Europe and Asia.
