Name Grabens and Horst in and around the Tr-State Areas?

In the Tr-State area, particularly around the New York, New Jersey, and Connecticut region, notable grabens and horsts can be found in the Appalachian Mountains. The Newark Basin represents a significant graben, characterized by its down-dropped block of land between two fault systems. Conversely, the surrounding highlands, such as the Watchung Mountains, are examples of horsts, which are elevated blocks of the Earth's crust that have remained uplifted relative to the down-dropped grabens. These geological features illustrate the complex tectonic history of the region.
