674 W. T. LEE STRATIGRAPHY OF COAL FIELDS OF NEW MEXICO 



No. Date. 



The mines at Monero are described, where three beds of coal 

 ranging in thickness from 3 feet 6 inches to 3 feet 10 inches 

 have been opened.

 districts (New Mexico).

 1898. 



The coal-bearing rocks outcropping on the Rio Puerco (p. 97) 

 and those of the Tijeras field (pp. 108-109) are described as 

 Cretaceous. 



(P. 112) The coal beds of the Cerrillos field at Waldo, Madrid, 

 and Omera are briefly mentioned. A sketch map of the geologic 

 formations accompanies the paper.

The statement is made that above the Dakota "comes a series 

 of shales, known to embrace the Benton, Niobrara, and a part 

 of the Pierre, which can not be divided on lithologic grounds. 

 The upper part of the section . . . consists of massive sand- 

 stones in which both the Fox Hills equivalent and that of the 

 Laramie may prove to be present." No mention is made of the 

 Lewis shale.

The coal mines near Madrid in the Cerrillos field are de- 

 scribed and the geologic relations of the coal beds shown by 

 columnar section. 



The mines at Monero are also described.

(Pp. 4 and 5) The coal-bearing rocks are described as the 

 Mcsai;erf/e ' formation and are underlain by Mancos shale and 

 overlain by Lewis shale. 



(P. 4) The Lewis is described as about 2,000 feet thick. The 

 occurrence of coal-bearing rocks above the Lewis is noted, but 

 doubt is cast on their assignment to the Laramie. 



(P. 5) The lower part of the Mancos shale contains the fol- 

 lowing characteristic Benton fossils: Grijphwa Jicivhcrnji ; Os- 

 trea luguhris; Ostrca congesta; Inoceramus labiatiis: Inoccra- 

 mus frogilis; Inoccj-amias (fimidius; Prionocuclus wacomhi: 

 Baculites gracilis; Scaphites icarrciii; Anatina sp.?; Plicatula 

 n. sp. 



The upper part of the Mancos contains the following Pierre 

 fossils (this revised list has been prepared for the present paper 

 by T. W. Stanton): Inoceramus harahini; Inoceranuis sp. ; 

 Inoceramus sagensis; 8yncyclonema rigida; Scaphites sp. ;
