b), Klein et al. (1984), Geraldes & Netto (2004a), Silveira et al. (2005), Valente et al. (2005), etc., concluded the pyroclastic rocks and their neighbours present at the Contenda Rock are pyroclastic flows, using the layered structure as proof. Motoki et al. (2007c) concluded the development degree and horizontal continuity of the pyroclastic textures are too poor for a pyroclastic flow deposit. The pyroclastic rocks along the Eugênia River are exposed, forming pyroclastic dykes, presenting underground subvolcanic fissures. If the pyroclastic rocks originated from pyroclastic flows, the deposits should have been widely present in the Fluminense lowland, such as Mesquita, Nilopolis, Nova Iguaçu, and Duque de Caxias. Welded pyroclastic rocks resist weathering and are therefore easily identified. Such volcanic deposits are not found in the Fluminense lowland. This confirms that these pyroclastic rocks were not created in pyroclastic flows. Present conclusion of the scientific works In recent years, the hypothesis of the Nova Iguaçu volcano has been an ardent discussion in scientific events and geological journals, being a controversial theme of the local geology. Research has clarified the inexistence of crater, cone, bomb, lava, and pyroclastic flow, and the scientific problems of the previous works were pointed out one by one. In this situation, the research groups favorable to the volcano hypothesis maintain their silence in academic communities. In this way, the geological studies of Nova Iguaçu are arriving at a new paradigm, that is, the inexistence of Nova Iguaçu Volcano. References Carioquinha. 2006.
