Metasedimentary Lithics of North Carolina

[gregszybala]

Metasedimentary stone was used to some degree, most notably argillite was occasionally used .The soft nature of this stone and less-than-desirable flaking quality usually precluded its use for other than utillity tools such as choppers.When fresh its color is dark green, otherwise it appears in various shades of light greens and greys. The most notable metasedimentary lithic is green metasiltstone, and is quite rare. It is a very fine-grained, waxy material, comparable to high-grade chert.The color ranges from dark to light lime green. The source of this stone is unknown, but probably in the southern Uwharrie Mountains.
