These fairy stones are typical of the Abitibi-Temiskaming region of Québec, Canada. They are concretions, somewhere midway between the mineral and fossil kingdoms. A large family, their origins vary also. These stones are characterized by being rather flat, with one somewhat smooth side and the other side generally covered with lines within concentric circles. These lines are actually plant filaments coming from horsetails or algae, and remind some people of ancient hieroglyphs. Therefore these fairy stones can also be considered fossils. Usually they have formed as concentric circles around the stem of a horsetail, and sometimes there still is a section right in the middle of a circle! The omnipresence of these plant filaments allow us to believe that they play a key role in the formation of these concretions, actually being the starting point of their growth! We can also explain the formation of very large concretions by the presence of several initial starting points which then grew and eventually melded together. Some are perfectly circular and others are somewhat elongated. Both forms are characteristic of bacterial activity. It seems that in a swampy Environment with very shallow water, carpets of gelatinous bacteria flourished, and their remains furnished the raw material needed to begin the formation of these concretions. Another element seems to confirm this hypothesis: The presence of a good quantity of silica in these concretions. Horsetails are plants that are particularly rich in silica. Bacteria reject silica because they can\'t digest it. Calcium carbonate being abundant in these cold waters, it then cemented all this together in the form of a rock which we call fairy stone. Therefore like stromatolites these fairy stones are created by bacterial colonies. However stromatolites formed at a much slower rate, and photosynthesis was present too. Fairy stones formed relatively rapidly, as every ring shows a growth period that was interrupted by dry or colder periods. This briefly explains the extraordinary forms of concretions that are found in the Abitibi-Temiskaming region and that inspired First Nations, in this case the Algonquin, to call these creations \'Fairy Stones\'.
