EARLE, INTERBEDDED IRON ORE DEPOSITS 123 



Two other separate occurrences of this Clinton ore have been noticed. 

 One of them is a short spur extending from Kentucky into the southern 

 portion of Ohio. In Kentucky, it appears in Bath, Montgomery and 

 Fleming Counties. In Ohio, it is found in Clinton, Adams, Highland 

 and Muskingum Counties. The other occurrence, which is of no present 

 importance, is that of Missouri, where in Holt County a deep borehole 

 revealed a seam of fossil ore in what appeared to be Clinton strata. 



From this outline, it is clear that these deposits are of great extent, 

 and that this feature must be reckoned with in accounting for their 

 origin. 



Other Paleozoic Deposits 



wabana deposit. newfoundland 



The Wabana deposit, one of the largest deposits of interbedded iron 

 ore in the world, is located on Belle Isle, in part, and extends for a con- 

 siderable distance under the waters of Conception Bay, Newfoundland. 

 The properties have been estimated to contain 3,635,000,000 tons of 

 hematite iron ore (170, pp. 745-752). 



Conception Bay on the east is bounded by a shore of Huronian strata, 

 which overly an anticline of Laurentian age, but are not conformable 

 with it. The western shore of the bay is regarded as pre-Cambrian. 

 Between these shores is a great synclinal trough of sandstones, slates and 

 shales of Cambrian age. The upper strata forms Belle Isle and contains 

 six beds of hematite, two of which are being worked at present. They 

 show the following section (Symons; 328, p. 1009) :
