Summary:
Named for great development in NV. [no type locality designated] Occurs in Mahogany Group [Hills], northern Fish Creek Mtns, Modoc Peak, Silverado Group [Diamond Mountains], Alhambra Hills. One exposure in Fish Creek Valley. Mainly composed of limestone, but intercalated beds of shale and saccharoidal texture, quartzite occur. Generally lower strata are indistinctly bedded, highly siliceous, and gray in color, passing up into brown, reddish-brown, and gray beds which are distinctly bedded and frequently banded producing somewhat variegated appearance; upper strata are more massive, usually well bedded and normally bluish black limestone. Thickness of longest continuous section estimated at 5,400 ft. Grades into underlying Lone Mountain dolomite (Silurian); contact arbitrarily placed, with poorly defined lithological distinctions. Conformably overlain by White Pine shale (Devonian). Contains rich and well preserved fauna of brachiopods and corals (and a ctenacanthus-like tooth). Age is Devonian (upper Helderberg, Hamilton and Chemung).

Summary:
Type section: sequence exposed at Modoc Peak [39 deg 30' 04"N 116 deg 02' 29"W], Roberts Mountain quad [now Whistler Mtn. 15' quad], Eureka Co, NV. Restricted to lower 2,448 ft of Devonian strata above Lone Mountain formation as exposed at Lone Mountain; upper 2,065 ft of Devonian strata exposed at Devils Gate and in Modoc Ridge are named Devils Gate formation (new). Lower limit of Nevada formation drawn at top of barren, more or less massive dolomite of Lone Mountain formation. Upper limit arbitrarily established at top of Stringocephalus zone. With lowering of the upper limit of Nevada fm to top of Stringocephalus zone it appears desirable to abandon use of the term "Nevada limestone" (Spencer, 1917 p.25) for those beds in Ely area which seem to correlate with the Devils Gate. Early and Middle Devonian ages.

Members appear to be valid for a N-S distance of more than 25 mi in Diamond Mtns and W of Eureka at least in part. Overlies Lone Mountain formation; underlies Devils Gate limestone. Contact between Lone Mountain and Nevada may represent unconformity based on sedimentary breccias below contact and sandstone above it. Upper contact with Devils Gate recognized by lithologic change from limestone to dolomite occurring within narrow zone of about 50 ft in thickness. Measured sections at Lone Mountain, Newark Mountain, Alhambra Hills and Phillipsburg Mine. Age is Early and Middle Devonian based on brachiopods and corals.

Lower part consists of thin-bedded limestone with buff and reddish partings (250 to 350 ft thick). Upper part consists of massive medium-gray to bluish-gray limestone (between 1250 and 1350 ft thick. Total thickness about 1500 ft. Unconformably underlies Pilot shale (Mississippian) and locally in fault contact with overlying Lone Mountain dolomite. No Stringocephalus fossils occur.

Summary:
Occurs in N Simpson Park Range (Coal Canyon) [Horse Creek Valley 15' quad, Eureka Co, NV]. "Between the Roberts Mountain formation and Nevada formation is lithologic unit not recognized in Roberts Mountains but which may correlate with similarly placed unit in Copenhagen Canyon, 50 mi south in Monitor Range. Unit, termed "Rabbit Hill formation" by Merriam (oral commun.) consists of tan-weathering silty limestone and calcareous shale, lighter colored than underlying Roberts Mountain formation and more silty and thinly bedded than overlying Nevada formation. Contact with Roberts Mountain and Nevada formations appear conformable and gradational. Is very fossiliferous, lower beds being rich in TENTACULITES and upper beds rich in brachiopods (mainly small LEPTOCOELIA) and trilobites. According to Merriam Rabbit Hill formation at its type locality contains Helderbergian or lowermost Devonian fauna and our fossils from this unit are similar."

Summary:
Recognized in Hot Creek Range, Tybo quad, Nye Co, NV. In least altered section predominantly limestone containing scattered lenticular layers of carbonate breccia; dolomite occurs in basal part. Most prominent breccia (25 ft thick) occurs at top in Rawhide Mtn area. Fossils from uppermost 100 ft are late Middle Devonian age. Fossils from 50-75 ft above base are medial Middle Devonian age. Westernmost Nevada exposure in upper Empire Canyon is fine-grained quartzite. Total thickness over 650 ft. Unconformably underlies Eleana Formation (Mississippian). Overlies Devonian beds, probably correlative with Lone Mountain Dolomite. Age is Early and Middle Devonian.

Summary:
In Lone Mountain divided into five (ascending 1 to 5): 1) at Coral Gulch consists of 260 ft of thick-bedded dolomite, dolomitic limestone, and light to mouse-gray limestone; overlies Lone Mountain Dolomite; contains ACROSPIRIFER KOBEHANA fauna (about Emsian age); 2) at Coral Gulch and upper Fossil Gulch, consists of 720 ft partly argillaceous, thin-bedded and shaly bands; contains abundant favositid head; is Early Middle Devonian age; probably correlates with Oxyoke Canyon Sandstone Member in Diamond Mtns; 3) on south side, consists of 285 ft. of dark-gray, well-bedded and relatively nonargillaceous limestone scarce fossils tending to be crinoidal debris; 4) west side of ridge between Reef Point and North Peak consists of 675 ft of well-bedded dense, resistant, fine-grained limestone, dolomite limestone and dolomite (dull mouse to medium dark gray, weathering light gray), and abundant colonial rugose corals (middle Middle Devonian) equivalent to Woodpecker Limestone Member (Nolan and others, 1956); 5) at summit ridge between Flag Point and North Peak consists of 570 ft of thick-bedded and massive saccharoidal dolomite and dolomitic limestone of dark to light-gray color; contains deposits of STRINGOCEPHALUS; is approx equivalent of Bay State Dolomite Member. Units 1 and 2 also occur in Sulphur Springs Range. Nevada formation may also be represented in Hot Creek Range (H.E. Cook, written commun, 1966)

Summary:
Recognized in Carlin-Pinon Range area. Includes measured sections for an upper dolomite member, Oxyoke Canyon Sandstone Member and Beacon Peak Dolomite Member which are shown on map. Three upper members in Eureka area (Nolan and others, 1956) are equivalent to [unnamed] upper dolomite member. Thickness of Nevada Fm from 1600 to 3200 ft in area of report. Underlies Devils Gate Limestone; overlies Lone Mountain Dolomite. Fossils are scarce and poorly preserved; coral "spaghetti" beds occur throughout area. Early and Middle Devonian age established from studies S of mapped area.

"Because every member of the Nevada Formation possesses all the characteristics of a formation, we here elevate each of its members to formation rank and abandon the name Nevada Formation." p. 1 [authors do not mention Nevada Formation in areas where it is not subdivided into named members, e.g., in White Pine Range, Windermere Hills, Nevada Test Site, Hot Creek Range, etc.]

 Overview
   

Summary:
Includes history of stratigraphic nomenclature of Nevada Limestone, Formation and "Group" in central Nevada. Abandonment of name "useful change because Nevada was collection of distinctive rock units deposited in variety of depositional environments: (1) western belt predominantly limestone and including slope-deposited and basinal rocks (the Denay Limestone); (2) an eastern belt, predominantly dolomite of shallow-water origin, (in Diamond Range); and (3) transitional belt in which major lithofacies intertongue (the Modoc Peak area)."
