A bacterial mat is a layer of bacteria that may form in environments where other organisms are unable to thrive (e.g. rock faces, ice shelves). In many cases, such a layer is not described as a "mat" until it becomes sufficiently thick to be visible to the naked eye.

Sharp chromatic stratification in mats was common with regions of mineral precipitate often forming between layers (Figure 8), and lake 128 possessed a unique pink bacterial sequence with an overlying 10 cm thick halite pavement.
Mat layers were generally underlain by white-pink carbonate, gypsum or halite precipitate, and varied from very fine clay/silt sized particles to coarse sands, and platy aggregates of mineral, coral or shell rubble.
Previous mat layers were incorporated throughout sediments underlying the upper bacterialmat, and occurred as red, green or brown sub-millimeter laminations (Figure 9).
