The destruction of Iapetus and Tornquist's Oceans
The Cambro‐Ordovician Iapetus and Tornquist's Oceans formed a Pacific‐type ocean basin rimmed by volcanic island arcs and marginal basins. By the latest Ordovician to earliest Silurian this ocean basin was beginning to close, to become a Mediterranean‐type ocean basin. This was caused by the co...
