Magnesite formation in playa environments near Atlin, British Columbia, Canada

Power, Ian M; Harrison, Anna L.; Dipple, Greg; Wilson, Siobhan A.; Barker, Shaun L.L.; Fallon, Stewart


The hydromagnesite–magnesite playas near Atlin, British Columba, Canada are unique Mg-carbonate depositional environments that have formed at Earth’s surface since the end of the last deglaciation. This study elucidates the mechanisms, pathways, and rates of magnesite (MgCO3) formation in these near-surface environments, which are challenging to study in short-duration laboratory experiments because magnesite precipitation is extremely slow at low temperature. The Atlin playas, having formed...[Show more]
