Abstract

Water found as active leaks and isolated pools in the Weeks Island, Jefferson Island, and Belle Isle salt mines of S Louisiana has del 18O values ranging from -4 to +ll.5%o and delD/% values from -2.3 to -53%o. Most samples are too enriched in 18O to be meteoric waters. It is concluded that the nonmeteoric waters are formation waters which have become incorporated in the salt. From the observed 18O enrichment it is calculated that the formation waters were incorporated during diapiric rise of the salt at a depth of 3-4 km and have been trapped within the salt for 10-13 m.y. Large volumes of salt within salt domes are not naturally penetrated by meteoric groundwaters but can contain limited amounts of trapped formation water. - from Authors
