PROBABILITY OF PENN8YLVANIAN GLACIATION OP THE ARBUOKLE AND 

 WICHITA MOUNTAIN REGIONS 



BY SAMUEL WEIDMAN 



{Ahstract) 



The paper will describe briefly the evidence of the glacial origin of the 

 Franks conglomerate of the Arbuckle Mountains and also will refer to a sim- 

 ilar type of conglomerate of the Wichita Mountains. The Franks conglom- 

 erate occurs at the base of the Pennsylvanian and there are associated con- 

 glomerates of similar type at several higher horizons developing a series of 

 thick conglomerates within the Pennsylvanian. The glacial origin of the con- 

 glomerate is indicated by: (1) The character of the conglomerates, such as 

 the large size and variety of boulders; (2) the non-residuary character of the 

 constituents of the conglomerate; (3) the great thickness of the conglomerate, 

 up to 500 feet; (4) the presence of polished, striated, and faceted boulders 

 and pebbles in the conglomerate; (5) the occurrence of polished, striated, and 

 grooved surfaces on which the conglomerate rests.

DEVONIAN BLACK SHALES OF WESTERN NEW YORK 

 BY GEORGE H. CHADWICK 



{Ahstract) 



Much greater thickness and extent of these possibly important oil-shales 

 than previously reported have been shown by detailed mapping, especially in 

 the case of the Dunkirk shale, which in eastern Erie County exceeds 160 feet 

 of solid black.
