The attractiveness of chlorine in hydrologic studies is that it is highly soluble, exists in nature as a conservative non-sorbing anion, does not participate in redox reactions, and has some quickly identifiable sources (e.g., seawater).
The abundance of Cl/Cl ratios (Bentley et al., 1986; Phillips et al., 1986; Nolte et al., 1991).
ABSTRACT: Chlorine and bromine play crucial roles in atmospheric element cycles and are important environmental tracers in catchment investigations, so understanding their distribution at the Earth's near-surface is imperative for deciphering their behaviour.
This study presents the first continental-scale analysis of Cl− and Br− concentrations of wet deposition, based on six and half years of weekly samples collected across North America.
Radiometric dating is also used to date archaeological materials, including ancient artifacts.
Additionally, large amounts of Cl has seen use in other areas of the geological sciences, including dating ice and sediments (Nishiizumi et al., 1983; Phillips et al.,1983).All ordinary matter is made up of combinations of chemical elements, each with its own atomic number, indicating the number of protons in the atomic nucleus.Additionally, elements may exist in different isotopes, with each isotope of an element differing in the number of neutrons in the nucleus.Among the best-known techniques are radiocarbon dating, potassium-argon dating and uranium-lead dating.By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change.Here Olwen Williams-Thorpe and colleagues, who have argued for the glacial transport theory, show that the Chlorine-36 dates have been misinterpreted.
