| Abstract | Formation waters of the Beaufort-Mackenzie Basin, Arctic Canada, show a broad range of salinity and water chemistry. Three main water types are defined: freshwaters related to a gravity-driven flow
system, original trapped seawater with minor diagenetic alteration, and low TDS - high alkalinity waters. High alkalinity waters are isolated in overpressured fault blocks characterized by rapid sedimentation and burial. The high alkalinities (up to
9000 mg/l) are interpreted to be related to in situ CO2 generation through anaerobic methanogenesis during burial. |
