There are a lot of wide ranges of Arc-collision stage age and Gondwana collision age!!
Dear Osama: your question is utterly incomplete. What do you mean by age of the "Gondwana collission", the Panafrican Orogeny which formed the Gondwanaland supercontinent, also known here in South America as the Brazilian Orogeny? And also, to which "arc" are you referring? No idea! All I can tell you is that the Panafrican-Braziliano event has an age around 650-550 Ma. So I beg you to be more specific. Regards, Sebastian.
Dear Dr Sebastián Grande, thanks for your interest. I asked about The final collision between East and West Gondwana and Arc-Arc collision stage.
Dear Osama: well, so you are indeed referring to the Neoproterozoic-Eocambrian Panafrican Orogeny, as seen in Eastern Africa (Mozambique Belt), South Africa (Cape Belt) southern Brazil, Antarctica, Australia, India and elsewhere. The timing of such a large tectonic event in not restricted whatsoever, it took more than 100 Ma to assemble Gondwanaland from various Paleozoic continental blocks, volcanic arcs, and alocthonous terranes generated by the rifting of supercontinent Rodinia. We don't have any recognizable Panafrican-aged rocks in Venezuela (only some detritic zircons show the age range 650-550 Ma), in this continent the event affected mostly southern Brazil, where it is called Braziliano Orogeny, coeval with similar events and belts in Nigeria-Niger. Information about these events can be found in the magazine Gondwana Research, to which I suppose you can access (we cannot access it here, it is simply prohibitive...). Regards, Sebastian.
