By Robert C. Horton

Barite deposits i n Nevada are concentrated w i th in a belt 50 to 75 miles wide extending northeast-southwest across the center o f the State. This "barite belt" coincides with the AntIer orogenic belt.

Fissure vein deposits are found in the southern portion of the belt, while both fissure vein and replacement type deposits occur i n the northern portion. The re- placement deposits, sometimes referred to as bedded deposits, have been the most productive.

The location, production, development, and geology of 60 mines and prospe,cts i n Nevada are given i n l i s t form.

This report brief ly describes each known occurrence of barite in Nevada and provides a summary of present know ledge based on a I I avai fable ~nformat~on, pub- lished and unpublished, some of which has not been verified by field examination *

It i s hoped that the report w i l l stimulate further exploration for barite deposits i n the State. nformation on barite occurrences acquired after publication of this report w i l laced on f i le at the Nevada Bureau of Mines, where i t w i l l be avai lable for examination. The ureau and the author w i l l appreciate receiving information about other occurrences of barite i n Nevada, as well as additional data or corrections for the OccurrenceS described in this report.

Persons and firms interested in barite mining i n Nevada have ~ o ~ ~ j b ~ t e d much valuabie ~ n f o r m a t ~ o n to make this publication possible. Donald A. Brobsk of the

S. Geological Survey and A. C. Johnson of the U. S. Bureau of Mines provided geological and location information concerning many of the properties.

Barite occurs i n fissure veins i n a l l types of rocks and i n replacement i n reactive rocks, usually limestone or dolomite. Residual deposits formed by the weather~ng of barite replacement deposits are o f importance in Missouri , Tennessee,

Georgia, and other southern States. Residual deposits have not been found in Nevada, but both fissure vein and replacement deposits have been mined.

rite deposits in evada are within a belt some 50 to 75 miles wide extending northeust-southwest across the center o f the State, as shown on the index map, plate 1 (foldout inside rear cover)." The "barite belt" coincides with the Antler orogenic belt as described by Roberts and others (1 958, p. 2813-2857). Although the significance of this coincidence i s not presently known, i t is of definite value as a guide to future exploration.

The deposits i n the southwestern portion o f the be l t are generally limited t fissure vein iypes. The production from this area has not b n great, but substantia amounts of barite have been mined and shipped to Southern alifornia (1 The deposits i n the northeastern hal f o f the belt include both fissure n and replacement type deposits, with the replacement type having been by far the most productive. These deposits were proba formed by bar~um-r~ch solutions that or~g~nuted at depth * In many instances the lacement i s so subtle that i t is d ~ ~ ~ i c u ~ t to recognize the dif- ference between the barite and the unreplaced limestone without hefting a specimen to estimate i t s specific gravitye The absence of both accessory minerals such as pyrite and galena, common i n many barite deposits, and of visible alteration affects, has led some observers to conclude that the barite i s of sed~mentary origin. The term "bedded deposits" has been used i n the l iterature i n some instances to avoid the genetic implications of the terms "replacement" and "sedimentary. 'I Detailed geologic mapping may answer the question o f origin, but i t presently appears that the barite occurs i n formations o f widely differing ages, suggesting a replacement origin. In addition, the presence of numerous fissure vein deposits suggests that the "bedded deposits" are epigenetic .

Sales o f barite increase or decrease i n propor~ion to increases or decreases i n o i l wefl-dri l l ing act iv i ty . Although there are many uses for barite, the industry depends on the w e ~ ~ - ~ ~ i ~ ~ j n g market for over 90 percent of i t s sales. Barite used i n dri l l ing muds must usually meet the following requirements: contain a minimum o f 92 percent BaS84 (barite), be free of soluble salts, have a specific gravity of at least 4.2, and 90-95 percent of the material must p a s s cp 325-mesh screen.

Most of the Nevada barite product~on is used i n wel l drill ing in ~ u ~ ~ f o r n ~ a ~ with the exception o f the barite produced by the 5aroid ivision, National Lead Company. This company operates the Rossi mine i n Elko County and ships much of the mine production to a company-owned chemical plant at Modesto, California.

Barite product~on began in Nevada in 1907 when a small amount of barite was mined a t the American Barite mine in Esmeralda County. The Yerington mine in

rmsby County is mentioned a s having produced bar i te in 1909. The Crystal mine i n Mineral County was a n act ive producer from '191 6 through 191 9, and again during the 1920's and early 1930's.

The development of the present Nevada bar i te industry began during the late 1930's. Nevada barite mines have produced over 1,300,000 short tons of barite with a value i n excess of $8,500,000. Most of this production has come from the replace- ment type deposits in the Battle Mountain-Carlin a rea of Lander, Eureka, and Elko Cow nti e s .
