Phliip C. Laporta. "Lithostratigraphic Models and the Geographic Distribution of Prehistoric Chert Quarries within the Cambro-Ordovician Lithologies of the Great Valley Sequence, Sussex County, New Jersey." Journal of Middle Atlantic Archaeology, vol. 10, pp. 47-66 |
|
| ABSTRACT: Nodular chert occurs within all 13 members of the Cambro-Ordovician Kittatinny Supergroup of northern New Jersey, yet very little is known about their origin and history. Research studies in the Wall kill Valley of New Jersey indicate that the cherts form by pore-filling, dissolution, and replacement mechanisms. Because laterally persistent chert sequences can be utilized as marker horizons, detailed stratigraphy could be worked out on the basis of formation-formation variations in megascopic and mesoscopic texture and structure. The primary goal has been to use textures to develop models of the origin and diagenetic history of nodular cherts. A second goal has been to create geological models which accurately predict the locations of prehistoric chert quarries. A third goal has been to correlate the physical and chemical properties of prehistoric chert artifacts with specific chert horizons and even to one of the more than 300 chert quarries that have been located in northern New Jersey and southern New York. |
