They are most beneficial where quantitative dating methods (i.e.
radiocarbon dating) cannot be used or do not adequately constrain the timing and relationship of geologic processes and events.
Integration of these data led to the recognition of certain geologic indicators that assist, either directly, or indirectly, in "filling the gaps" in the geologic history of the Atlantis area.
The obtained ages range 4 to 16000 years, showing that the ESR method has a wide application age range. The barite crystals occur in sulfide chimneys and in deposits, incorporating radium ions that are in the hydrothermal fluid.
As a radium ion has an ionic radius similar with barium, radium ions easily replace barium in barite to have high concentration up to several tens Bq/g of .
In this way, they play a vital role in assessing the past, present, and potential future rates geologic activity that is critical to the success of the Atlantis development.
Introduction BP America, Inc., and its partners are currently evaluating the feasibility of installing various production facilities along the Sigsbee Escarpment in the southern Green Canyon area, Gulf of Mexico (Figure 1).
