content: SB-1 (Blackgum Chert, Variety 1): Found in Cherokee Co. OK. only. This rare chert varies in texture from fine to medium coarse, often in one specimen. The color is variable, the most common being a mottled light to dark gray or light gray and tan. Some of the coarser textured chert has a pinkish hue. A 20X examination reveals this color comes from a myriad of tiny orange clay filled pockets. Crinoid and other fossil remains are found in the coarser and finer textured areas. Vugs completely filled with calcite or opaline silica are noted. One piece of fine textured chert superficially resembles Reeds Spring, but under 20X magnification small orange and pink spots could be seen embedded in the chert. Fossil inclusions remind one of Pierson. The exposed chert is brittle. Works fair to good.
