Final answer:
New Jersey is comprised of five geologic provinces: Valley and Ridge, Highlands, Piedmont, Coastal Plain, and Newark Basin. These provinces have diverse geological features and the Highlands primarily consist of intrusive igneous and medium grade metamorphic rocks.
Step-by-step explanation:
The five geologic provinces in New Jersey are Valley and Ridge, Highlands, Piedmont, Coastal Plain, and Newark Basin. These provinces are differentiated by their distinct geological features and history.
For example, much of the faulting and folding throughout the Valley and Ridge Province and the Highlands occurred during the Alleghenian Orogeny. The Newark Basin formed during the breakup of Pangaea during the Jurassic period.
The Highlands Province is primarily made of metamorphic and igneous rocks, and the igneous rocks found here are primarily intrusive. The metamorphic rocks are primarily of medium grade and are about the same age, including the Mount Eve Granite and the Hornblende granite of the Byram Intrusive Suite.
