Deposition of the Middle Devonian part of the Denay Limestone
and Bay State Dolomite in the northern Antelope Range and Fish
Creek Range, respectively, took place on and in front of a carbonate
platform with a lime sand shoal at the shelf edge. In the Givetian part
of the Denay...
Early Paleozoic limestones and dolomites of the shallow shelf
transitional facies belt were mapped in the southern Sulphur Spring
Range, Eureka County, Nevada. The four youngest units in the map area
are in fault contact with the Lower Devonian rocks and were probably
transported westward, along a low-angle normal fault....
In the southern Fish Creek Range, Nye County Nevada,
Devonian rocks are found overlying younger rocks. These
Devonian units are allochthonous blocks that slid by
gravity into their present positions.
The allochthonous blocks represent several different
provenances commonly found to the west and northwest of the
area. The blocks include...
The Upper Devonian Fenstermaker Limestone is a thickening-upward sequence
of interbedded sandy intrapelsparite and subordinate calcareous siltstone and mudstone
which averages 190 ft (58 m) thick in the northern Antelope Range. The Fenstermaker
Limestone is revised and restricted herein to include only those rocks above a basinal
shale sequence of...
Lower and Middle Devonian strata crop out on the former
stable carbonate platform that existed in the Quinn Canyon Range,
through the carbonate shelf edge in the Pancake Range, to the
carbonate slope and outer-shelf basin in the Reveille Range.
The strata of the Reveille Range record a transition from...
The Middle and Upper Devonian Guilmette Formation was deposited within the inner shelf region of the Cordilleran miogeosyncline. Twelve distinct lithofacies are recognized in the Guilmette Formation
and represent deposition from various peritidal environments including quiet-water lagoons, organic buildups, a barrier bar/beach complex, and intertidal through supratidal flats. The relative...
