Nova Iguaçu Volcano

I cannot write an encyclopedia article about the "Nova Iguaçu Volcano" because no web search results were provided, and this appears to be a fictional or non-existent geological feature. Nova Iguaçu is a real city in Rio de Janeiro state, Brazil, but it is not associated with any volcanic activity. Brazil has very limited volcanic activity, with no active volcanoes in the Rio de Janeiro region.

If you're interested in learning about real volcanic features in Brazil or South America, I'd be happy to write about topics like the volcanic islands of Fernando de Noronha, the Andes volcanic chain, or volcanic geology in general. Please provide a real topic with appropriate source material for me to create an accurate encyclopedia article.
