KEMP'S ORE DEPOSITS. 







Shepherd Mountain and 

 Cedar Mountain, whose 

 ores are structurally more 

 related to Example 11 a. 

 The first contains three 

 veins, the Champion, the 

 North, and the South. They 

 are long and narrow (4 to 

 10 feet), strike north 60 

 to 70 east, and dip 70 

 north. The Champion vein 

 contained a little streak of 

 natural lodestone, but the 

 ore is mostly specular. 



The North vein shows 

 a good breast of ore five 

 feet wide, but too full of 

 pyrite to be available. Ce- 

 dar Mountain has a vein of 

 specular ore. Neither hill 

 has been an important pro- 

 ducer. Minor veins have 

 been found on neighboring 

 porphyry hills (Buf ord, Ho- 

 gan, and Lewis mountains), 

 some of which contain 

 much manganese. 



2.02.34. Example 11. 

 Iron Mountain, Missouri. 

 Veins of hard, specular 

 hematite irregularly seam- 

 ing a knob of porphyry. 

 Iron Mountain is five or 

 six miles north of Pilot 

 Knob, and is a low hill with 

 a westerly spur called Lit- 

 tle Mountain, and has also 

 a northerly spur. It con- 

 sists of feldspar porphyries, 

 more or less altered. These
