Newton, Sussex Co., New Jersey, USA

This page is currently not sponsored. Click here to sponsor this page.
An incorporated town and the county seat of Sussex County.

Nearly all the minerals listed for "Newton" are, in fact, from the Limecrest Quarry. Although the quarry is in Sparta Township, Newton is the closest urban area. In the 19th century municipal boundaries were somewhat different than they are today and "Newton" came a lot closer to the actual site than it does today but, even then, did not extend quite so far. However, in older texts, the Limecrest locality was commonly given as "Newton".
The icon for Newton that appears on the Mindat map actually marks a residential neighborhood underlain by Ordovician Rickenbach dolomite (Drake, 1992, USGS GQ 1703). A few blocks away, there was a dolomite outcrop with an abrupt end that was called "crystal cliff" when I was a kid. There were small quartz crystals in the soil that had weathered out of veins in the dolomite.
