Abstract: To study the typical aspects of the phenomena in the superhigh energy region, that will be the main energy region of interest of the next experiments using nuclear emulsion chambers, we took the data of the superfamilies of the Brazil-Japan Collaboration and compared them with experimental detailed information of an event named PO6 with SIGMAE(gamma) > 1000 TeV of the same collaboration. These superfamilies were also compared with simulated families using different primary composition (P, CNO, Fe) and scaling-type interaction. In the correlation between hadrons and gamma rays we observed that some events were situated in the simulation region beyond fluctuation of the proton primary, scaling-type PS model, having big values of hadronic energy and hadronic number. So, we supposed that these events can be explained as coming from primaries such as C, N, O or that there is a change in the nuclear interaction, supposing, e.g. the exotic production of hadrons, such as Centauro and Chiron. Other events, however, are located in the PS region.
