Description: In this article, the authors apply the method of Diffusion Entropy (DE) to the study of stromatolites by means of a two-dimensional procedure that makes it possible for us to compare the DE analysis to the results of a compression method. As done with the compression method, the authors analyze two pairs of samples, one biotic and the other a-biotic. Each pair consists of a target, the putative stromatolite sample, and of its surrounding matrix. The authors use two different procedures, referring to single colors and to a color combination, respectively. The authors apply the DE method to both procedures and the authors find the same result, this being that the scaling index of the time series stemming from the biotic target yields a scaling index larger than the scaling indices of the other three curves. The authors argue that the DE analysis confirms the results of the compression method.
