These geochemical similarities are not found in coeval Tremadoc black shales of Bolivia, New York, Quebec, Wales, and Belgium. During the Paleozoic Era, the tectonic plate containing the continent of Laurentia and the plate containing the continent of Gondwanaland were converging, the Iapetus Ocean that separated the two continents gradually closed, and the resulting collision between the plates formed the Appalachian Mountains. Staten Island-Wikipedia the Iapetus Ocean in the Ordovician and Silurian (Fig. 1), although, of course, at the time of continental rifting (c. 600 Ma) they may have been facing away from each other (McKerrow et al.
1), although, of course, at the time of continental rifting (c. 600 Ma) they may have been facing away from each other (McKerrow et al. 1992; Torsvik et al. 1996), and during their palaeogeographic evolution they may have faced diﬀerent parts of that ocean. Although Iapetus was still at that time a mighty ocean, the slow process of its destruction had already begun, for the great continents of Laurentia, Baltica and Avalonia were advancing inexorably towards one another, trampling Iapetus underfoot as they went, forcing it down into the depths of the Earth’s mantle. Ireland has a rich and diverse geological history spanning from 1.8 billion years ago to today.

Iapetus Ocean (proto-Atlantic) The late Precambrian and early Palaeozoic ocean that lay between Baltica and Laurentia. The oceanic crust and upper mantle of the Iapetus Ocean floor is presumed to have been subducted during the early Palaeozoic, and the ocean to have disappeared completely by the latest Silurian —early Devonian (about 400 Ma).

Included in the paleogeographic reconstruction are cold and warm ocean currents. The present-day coastlines and tectonic boundaries of the configured continents are shown in the inset at the lower right.
