No. Date. 



A part of this paper is devoted to tlie "Oniara Coal Field," and 

 the coal beds at the Omara mine are correlated with those near 

 Madrid. (These localities are at opix)site extremities of the 

 Cerrillos field.)

The coal-bearing formations of the southeastern part of the 

 San .Tuan Basin are described as Mesaverde and "Laramie." A 

 detailed section of the Mesaverde on Arroyo Torrcn^ns (p. 470) 

 shows a thickness of 1,328 feet. 



The statement is made (p. 462) that the Mesaverde "Is now 

 known to encircle the San Juan Basin. The same is true of the 

 overlying conformable Lewis shale and 'Laramie' formation."

The Tertiary and late Cretaceous formations of the San Juan 

 Basin west of Nacimiento Mountains are described. 



The Tertiary beds rest uncouformably on the "Laramie," and 

 the Mesaverde coal measures are separated from the "Laramie" 

 by the Lewas shale.

 stone and the lower plate of this sandstone are referred on fossil 

 evidence to Comanche. The upper plate of sandstone is referred 

 to Dakota.
