layers making more massive beds that break up on exposure to the 



influence of the atmosphere 150

On the northeast slope of Quartz Peak there is a heavy mass of light 

 gray siliceous limestone, roughly estimated at 1,000 feet, without fossils, 

 which, by its stratigraphical position and lithological habit is easily 

 referred to the upper beds of the Lone Mountain, a continuation of the 

 beds upon the summit of the peak as given in the section. To the south of 

 Quartz Peak occurs a great development of limestone. A section across 

 the beds is of special interest, owing to the thickness of the limestones 

 from the Lone Mountain to the Carboniferous, which is unbroken by the 

 presence either of Diamond Peak quartzite or White Pine shale, as in both 

 the Eureka and White Pine sections. The section is as follows: 



CARBONIFEROUS. 



Feet. 



1. Siliceous limestone, sandstone, and quartzite 500 



2. Cherty siliceous limestone 250 



3. Shaly limestone in massive layers 55 



4. Massive bedded gray limestone, hard and compact ; it passes into gran- 



ular dark gray limestone and then into more thinly bedded bluish 



black limestone 1, 260
