GeoFile 2004-1: Ultramafic Rocks in British Columbia - Applications in C02 Sequestration and Mineral Exploration
View GeoFile (PDF, 5.92 MB)
A map of all major dunite and or serpentinite localities in BC has been compiled. This map is an essential tool in planning for CO2 sequestration in BC as well in some exploration plays and industrial mineral compilation. One form of CO2 sequestration involves trapping the CO2 in magnesium silicates to form silica and magnesite (magnesium carbonate).
Suitable targets should be near major CO2 point source, the resource should be large enough to sequester 10kT a day and the dunites should be free of serpentinite, and low in CaO, LOI, and CO2. One area under discussion is the Tulameen Complex in southern BC, another, at Cassiar in Northern BC, would utilize the sequestration in transformation of potentially harmful asbestiform magnesium silicates to magnesite and silica.
