Bedrock Geologic Map of New Jersey

New Jersey has two rather different regions. The south half of the state is on the low, flat-lying Atlantic coastal plain, and the north half is in the ancient folded Appalachian mountain chain. The state is rich in fossils, and the thick basalt intrusions (bright red) of Jurassic age are well known among mineral collectors. The state contains coal and metal ores that were extensively exploited from colonial times until the early 20th century.
The green-and-red oval marks a region where the crust split during the initial opening of the Atlantic Ocean. A similar feature is in Connecticut and Massachusetts.
I also have a larger version (850x1200 pixels) suitable for printing on a whole page. But for just fifty cents, you can order a nice printed copy from the state.
