Fossiliferous shale.

In zone LMX-3, the mixed shale shows relatively well-developed lamination, with generally light-colored detrital silt laminations interbedded with dark laminations composed of clay, organic matter, pyrite and some detrital grains. In addition, graptolites are abundant along the shale bedding planes, forming fossiliferous layers (Fig. 14 aHighly fossiliferous shale member 100 feet thick at base, upper 1 200 feet is dolomite in thick alternating black and light hands about 100 feet thick.

Shale weathers rapidly to mud, which washes away leaving the fossils behind. There are three major Mississippian age fossiliferous shale units in north Arkansas. From oldest to youngest they are the Moorefield Shale; the Fayetteville Shale; and the Imo member of the Pitkin Formation.The Gage Shale Member is mostly clayey shale, but calcareous fossiliferous shale and a minor amount of limestone occur in the upper part. The lower and middle parts are chiefly noncalcareous red, green, purple, and chocolate-colored shale interbedded with gray and yellow shale. The characteristic thickness is approximately 45 feet.
