An international team of scientists has discovered the oldest water source in the world, in crevices of the Witwatersrand, a chain of hills in South Africa, it dates back several million years.
The study was presented Monday in the framework of the International Conference, American Association for the Advancement of Science, Washington DC, writes Maxi Sciences.
On the basis of new evidence found in the area, the research team showed that the source of groundwater in the hilly area of Witwatersrand, South Africa, has a few million years old, featuring a high salinity and chemicals resulted in the dissolution time rare gas.
The findings were published in the journal Chemical Biology and concluded that the underground water source is found the oldest on Earth, has special properties and a special composition of rare gas and neon.
Barbara Sherwood Lollar of the University of London, said that this unusual element neon, which has accumulated millions of years allowed in ground water analysis to determine her age. Similarly, the signature of different chemical compounds and have high salinity groundwater indicated that it had no contact with surface waters.
