Mineralized microbially mediated biosignatures were observesd by optical rock microscopy in unequilibrated ordinary chondrites. Using routinly used methods in earth sciences, high resolution mineralogical and organic geochemical characterization was elaborated. Comparative interpretation with terrestrial analogies will be presented according to structural hierarchy, in the frame of which we offer the results for scientific discussion: terrestrial or parent body processes?
