The "Taconic Unconformity" is an angular unconformity exposed from eastern New York State to the Gaspe peninsula. As the Taconic orogeny subsided in early Silurian time, uplifts and folds in the Hudson Valley region were beveled by erosion. Upon this surface sediments began to accumulate, derived from remaining uplifts in the New England region.
Taconic orogeny. Algoman orogeny, also known as Kenoran orogeny – Late Archaean episode of mountain building in what is now North America – Superior province, South Dakota to Lake Huron, late Archean Eon (2700–2500 Ma) Wopmay orogeny – Mountain-building event in northern Canada – Along western edge of Canadian shield, (2100–1900 Ma)
The Taconic Unconformity, near Catskill, NY. The Taconic unconformity is a major unconformity created during the Taconic orogeny, exposed from eastern New York State to the Gaspe peninsula. [1] The orogeny was a long one that comprised multiple bursts; it primarily dated to the end of the Ordovician, and the underlying rocks are primarily this age.
The Taconic Mountains (/ t ə ˈ k ɒ n ɪ k /) are a 150-mile-long sub-range of the Appalachian Mountains lying on the eastern border of New York State and adjacent New England. The range, which played a role in the history of geological science, is separated from the Berkshires and Green Mountains to the east by a series of valleys, principally those of the Housatonic River, Battenkill River ...
It is important to know if the tectonic phase was a longer event or if it was local or regional. Tectonic phases can be important events that affected large areas. The Alleghenian orogeny in North America (during the Carboniferous period ) for example can be found as an angular unconformity between rock layers in large parts of that continent.
The Berkshires (locally / ˈ b ɜːr k ʃ ɪər z,-ʃ ər z /) are highlands located in western Massachusetts and northwestern Connecticut in the United States. Generally, "Berkshires" may refer to the range of hills in Massachusetts that lie between the Housatonic and Connecticut Rivers. [1]
