The Appalachians and Interior Lowlands of the North American Craton,ts apex near the Mexican border. The . in the northern part of this block remained, for the most part, a positive region receiving little or no sediment. The southern part, now forming the ., was repeatedly inundated and received a cover of platform sediments.

Gondwanaland in Late Palaeozoic Times,y separated cratons were welded together to produce a single, very much larger, stable unit. Orogenic activity continued in peripheral mobile zones which formed a nearly continuous girdle enveloping the newly consolidated craton (Fig. 6.1).

The Alpine-Himalayan Belt and the Eurasian Craton,stem encircling the supercontinents. It was transformed to a largely intra-continental structure by the collision of northward-moving fragments of Gondwanaland — Africa, Arabia and Peninsular India — with the Eurasian continental mass.

The Caledonides and their Forelands,until well into the Phanerozoic eon. In Laurasia (Fig. 2.1) this system was built around a fairly small number of cratons; most parts of the system remained mobile at least until the end of Lower Palaeozoic times and some are still in being at the present day. In Gondwanaland, the mobile belts enclo
