This extensive volume is a chronicle of the many current ideas on the an Orogen
This extensive volume is a chronicle of the many current ideas on the an Orogen. The volume is organized based on the symmetry that was recognized in the Newfoundland Appalachians over thirty years ago by Dr. Harold Williams of Memorial University of Newfoundland. This two-sided symmetry is manifested in three elements: the Laurentian margin (platform), the Iapetan Oceanic realm (mobile belt) and the Gondwanan-related terranes (platform). The geological evolution of these elements forms the focus of the first three sections of this volume.

Aeromagnetic and geological data from Tanzania reveal eight dyke swarms cutting the Precambrian craton that underlies most of the country. Only three swarms have adequate age control; one is post-Karoo ( 200 . and two are Precambrian approx 2400 and 800 . The remainder are suspected to be Precambrian. A vast ancient lake in the drainage basin of the Red River was recognized during explorations from 1823-1879. Warren Upham in 1879 started mapping the lake in Minnesota and named it glacial Lake Agassiz. He continued mapping in Manitoba and N Dakota and, with the work of . Tyrell and others in the N, produced a map of Lake Agassiz in 1890.

created the Appalachian orogen and subsequent basin. Tectonics of the Acadian Orogeny in New England and Adjacent Canada". The Journal of Geology. The preceding orogenies consisted of the Potomac and Taconic orogeny, which followed a rift/drift stage in the Late Neoproterozoic. The Acadian orogeny involved the collision of a series of Avalonian continental fragments with the Laurasian continent. The evidence for the Acadian orogeny is abundant and widespread in the northern Appalachians, recorded by the plutonism and the migration of the northern Appalachian deformation front toward the craton.
