three in review geology May 6. They discovered that the primary fluid inclusions in the halite in the Brown formation contained and the organic. Halite comes from the evaporation of salt lakes or seas resulting in rocks with a high concentration of salt, called evaporites. The studied sample originated from central Australia and was formed 830 million years ago.from West Virginia University (West Virginia University)Sarah Schrader-Gomez, Kathleen Benison and Jeremiah Bernau, Published
The organic traces present in this halite were determined by a method and organic compounds. It has also been observed that impurities of fluids that are trapped in them Served as their micro-habitat and allowed their exceptional conservation.Which made it possible to describe the size, shape and from Organic materials, and by ultraviolet visible (UV-vis) lithography method that shows the fluorescent response of any microorganism and organic compound present. These techniques revealed that the halite sample contained cells
Are these microorganisms alive?
To survive in highly saline environments, some organisms such as algae shrink and reduce their biological activity, then wait for better conditions to wake up.
However, it is not yet known whether living organisms are capable of this . Oldest halite Live dates were extracted about 250 million years ago, so it is possible that these microorganisms found in Australia were as well.
Until recently, it was suggested thatdestroying organic matter over long periods of time. But the discovery of these microorganisms in halite from 830 Ma Browne Formation is strong evidence that organic matter can be preserved in sediment crystals over a long geological period.
Way to find life on Mars?
Brown formation halite is similar in structure and properties to the rocks of Mars. In fact, Mars once knew areas of salt water in which halite could form by evaporation. Therefore, the results of this study indicate the possibility of maintaining similar in the sedimentary rocks of Mars, and thus could be a new avenue of investigation to see if Mars ever harbored life.
Therefore, the ancient sedimentary rocks, both terrestrial and extraterrestrial, still have much to offer in terms of information about the past, and it is therefore essential that Think of them as things that can be made up of life.
