erous.     Is  useful  for 
making  Portland  ce- 
ment and  for  build- 
ing purposes. 
Outcrops  are  contained  in  a  belt 
about  3  miles  wide,  extending 
diagonally  across  the  south- 
eastern part  of  the  quadrangle.

Compact,  semicrystal- 
line. 
Eastern  part  of  the  quadrangle, 
in  Big  Hill  Creek  region, 
northeast  of  Liberty.  Here 
it  outcrops  in  a  belt  3  miles 
wide. 
L  a  d  o  r  e  - 
Dudley 
shale. 
90 
Compact,     useful     in 
making  brick. 
Southeastern  part  of  quadrangle, 
in  a  belt  that  has  a  width  of  6 
miles  southeast  of  Liberty 
and  narrows  southwestward 
toward  Indian  Territory. 
Parsons  forma- 
tion. 
80 
Crystalline,    fossilifer- 
ous    limestone    and 
compact  shale. 
Crosses  southeast  coiner  of  the 
quadrangle  below  Coffeeville 
in  a  belt  5  to  6  miles  wide. 
Bandera  shale  _ .

Compact,  contains  con- 
siderable    thin- 
bedded  sand  stone, 
some  of  which  is 
quarried    for    flag- 
ging. 
Just  east  of  the  southeast  corner 
of  the  quadrangle,  in  a  belt 
trending  northeast- southwest.
