Supporting this hypothesis is the suggestion that the orogens have "truncated ends" that can be matched and that both share the commonality of having carbonate platform sediments at what is today their western side.
Para apoiar esta hipótese suxeriuse que o oróxeno ten "extremos truncados" que poden encaixar e que ambos comparten o feito de ter sedimentos de plataforma carbonatados no que hoxe son as súas partes occidentais.
