Labeled subunits in Lake Neosho Shale
The Lake Neosho Shale lies between the heavy dashed
lines. The
calcareous shale, blocky claystone, phosphatic shale, and bioclastic
shale units are labeled. The contact with the conglomerate and limestone
unit in the underlying Bandera Formation seems to be erosional. The
contact between the bioclastic shale and Worland Limestone Member
is also irregular, but that appears to be the result of lateral facies
change (see contact at far right).
