has found evidence that the water came from beneath the surface between 3.7 billion and 4 billion years ago and remained long enough to make carbonate-related clay minerals found in layers. McLaughlin Crater, one of the deepest craters on Mars, contains Mg-Fe clays and carbonates that probably formed in a groundwater-fed alkaline lake. This type of lake could have had a massive biosphere of microscopic organisms.Michalski, J., J. Cuadros, P. Niles, J. Parnell, A. Rogers, S. Wright. 2013. Groundwater activity on Mars and implications for a deep biosphere. Nature geoscience:6, 133–138.
