Summary:
Pg. 40. Cundiff limestone. Three ledges of limestone outcropping in eastern part of Jack County, central northern Texas, near Cundiff, take their name from the village. The Upper Cundiff limestone consists of 3+/- feet of hard crystalline limestone apparently of algal origin; it is present in Wise County, central northern Texas. The Lower [Middle] Cundiff limestone consists of 3+/- feet of hard crystalline limestone apparently of algal origin; it is present in Wise County and is separated from Upper Cundiff limestone by 75+/- feet of shale. The lower of the 3 limestone ledges pinches out before Wise County is reached. The Cundiff limestone overlies Hog Creek shales, both of which are members of Caddo Creek formation. [Age is Pennsylvanian.]
