    Gneiss Belt; GFTZ, Grenville Front Tectonic Zone Geological setting The Grenville Orogen represents one of the oldest linear orogenic belts stretching from Newfoundland in the north through eastern Canada, the eastern United States to Texas and central Mexico in the south. The Phanerozoic history of North America, when viewed from the perspective of Pangea, can be divided into three broad phases with gradational time boundaries, as described in the following paragraphs.. During the first phase, which lasted from the late Precambrian to the Pennsylvanian, Pangea was under construction and the North American craton was marked by various, Cited by: 6.

    Other articles where Grenville Orogen is discussed: North America: billion to million years ago: northwest-directed crustal-scale thrusting in the Grenville orogenic belt. The belt is exposed principally along the southeastern margin of the Canadian Shield, but inliers occur in the Appalachians, the East Greenland Caledonides, Texas, and Mexico.

    A prominent midcrustal discontinuity beneath the central Grenville Province and changes in the patterns of seismic anisotropy in the THO crust beneath Hudson Bay provide geophysical evidence that lower crustal flow likely played a role in the evolution of both orogens, similar to that inferred beneath the present‐day by: 8. Proterozoic Life Acritarchs & Plankton. The Proterozoic includes over half the history of life on this planet, but the available data about Proterozoic organisms are exceedingly sparse. We usually have a little discussion about plankton at about this point on the Time pages, but we know practically nothing about plankton in the Proterozoic.

North America is a continent that has grown over time by horizontal attachment of material onto its margins. Studying the process of continental growth in the geologic past gives insight into fundamental components of plate tectonics, and sheds light onto processes at work at modern plate boundaries, in which mid- and lower-crustal rocks are generally hidden from : Ruth Frances Aronoff.

The Phanerozoic history of North America can be divided into three broad phases: During the first phase, which lasted from the Late Precambrian to the Triassic, Pangea was under construction.
