Formation waters of the Beaufort Mackenzie Basin-deep biodegradation associated with rapid sedimentation and burial

摘要：

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 insitu CO2 generation through anaerobic methanogenesis during burial.
