Joel KontinenHeres WHAT Phys. org says about our past
Primary fluid inclusions in bedded halite from the 830-million-year-old Browne Formation of central Australia contain organic
solids and liquids, as documented with transmitted light and UV-vis
petrography. These objects are consistent in size, shape, and fluorescent
response to cells of prokaryotes and algae, and aggregates of organic compounds.
The researchers say that this may also happen on Mars, “that similar biosignatures may be able to be detected in chemical sediments from Mars.”
But only if the Earth was not cfeated for life.
