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 phase – Mountain-building period that affected most of New England – In the northeastern U.S. and Canada, during the Ordovician Period; Acadian phase – North American orogeny – In the eastern U.S., during the Silurian and Devonian Periods
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.
When new sedimentary layers are deposited on top of tilted ones, they will have an angle with the older ones, a structure which is called an angular unconformity. Any angular unconformity is proof that a tectonic phase took place between the deposition of the layers below and on top of it.

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 ...
