This was the final episode of the Taconic orogeny. [1] Cameron's Line is the suture zone that is modern-day evidence of the collision of the island arc and the continent. [ 3 ] Cameron's Line winds southward out of New England into western Connecticut and passes through southern New York across the Bronx , following the general trend of the ...

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 first phase that is often included in the Caledonian orogeny is the Finnmarkian Orogeny, which was an early deformation event in Arctic (northern) Norway which preceded the Scandian phase (see below) in this area. Its onset has been dated at c. 500 Ma (Late Cambrian). It continued to c. 460 Ma and was reactivated in the Scandian phase at ...
Any angular unconformity is proof that a tectonic phase took place between the deposition of the layers below and on top of it. 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 Acadian orogeny is a long-lasting mountain building event which began in the Middle Devonian, reaching a climax in the Late Devonian. [1] It was active for approximately 50 million years, beginning roughly around 375 million years ago (Ma), with deformational, plutonic, and metamorphic events extending into the early Mississippian.

The Alleghanian orogeny, a result of three separate continental collisions. USGS. The immense region involved in the continental collision, the vast temporal length of the orogeny, and the thickness of the pile of sediments and igneous rocks known to have been involved are evidence that at the peak of the mountain-building process, the Appalachians likely once reached elevations similar to ...
