Radiocarbon dating of salt water found in wells drilled into the bedrock in the coastal area of Finland

Abstract

Radiocarbon determinations of salt water drawn from some deep wells drilled into the bedrock confirmed the earlier suggestion that this ground water with a high chloride content is relic water from the time in the development of the Baltic when the coastal areas of Finland were submerged. An exact date cannot be given for the salt water because it has later been mixed with younger ground water.
