content: MK-2 (Mississippian Keokuk Variety 2): MK Variety 2. NW AR & SW MO. A light gray to off-white chert with numerous tiny (under 1 mm) dark gray spots and some minute silica particles (visible at 10 X). A few wispy light gray streaks may be seen on some examples. Outer cortex weathers tripolitic, and this part contains much crinoid detrius. The center of the cherty has very few fossils. Iron oxide coats fracture surfaces. Comes in large pieces. Workability very good to excellent.
