I9I4.] CONCEPTION AND TRINITY BAYS, NEWFOUNDLAND. 419 



219 F 7 is probably a continuation of 219 A 8 and 9 of Manuels 

 inasmuch as this bed is nodular and has many lenticular and con- 

 tinuous jaspery seams of o.i inch to i inch in thickness alternating 

 with Yz inch to i inch seams of reddish manganiferous shale. 



219 F 8 from its similarity to 219 A 13 of Manuels may be de- 

 scribed as a phosphatic nodular manganiferous shale with the man- 

 ganese in evidence as some hydrous oxide. 



Chapel Cove Section. — The manganese at Chapel Cove, of 

 inconsiderable amount, occurs in a very much faulted series of 

 lower Cambrian limestones and shales as alteration products on 

 many of the structural planes. If it were not for certain lithological 

 analogies with the deposits just described it would hardly seem 

 necessary to give any detailed description of this deposit because of 

 the small quantity of manganese present (see Figs, i and 37).
