Horton Barite deposits i n Nevada are concentrated w i t h i n 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 i n the southern portion of the belt, while both fissure vein and replacement type deposits occur i n the northern portion. The replacement 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 briefly describes each known occurrence of barite in Nevada and pubprovides a summary of present know ledge based on a I I avai fable ~nformat~on, lished and unpublished, some of which has not been verified by field examination * It i s hoped that the report w i l l stimulate further exploration for barite deposits i n the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 laced on f i l e a t the Nevada Bureau of Mines, where i t w i l l be available for examination. The ureau and the author w i l l appreciate receiving information about other occurrences o f barite i n Nevada, as well as additional data or corrections for the OccurrenceS described in this report. this report w i l ~ t e d Persons and firms interested in barite mining i n Nevada have ~ o ~ ~ j bmuch valuabie ~ n f o r m a t ~ oton make this publication possible. Donald A. Brobsk of the S. Geological Survey and A. C. Johnson o f the U. S. Bureau of Mines provided geological and location information concerning many o f the properties. Barite occurs i n fissure veins i n a l l types o f rocks and i n replacement i n reactive rocks, usually limestone or dolomite. Residual deposits formed by the weather~ngof barite replacement deposits are o f importance i n Missouri , Tennessee, Georgia, and other southern States. Residual deposits have not been found i n Nevada, but both fissure vein and replacement deposits have been mined. rite deposits i n 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 o f definite value as a guide to future exploration. The deposits i n the southwestern portion o f the b e 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 The deposits i n the northeastern h a l 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 ba r ~ u m - r ~ csolutions h that o r ~ g ~ n u t eadt depth * In many instances the lacement i s so subtle that i t is d ~ ~ ~ itoc recognize u ~ t the difference 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 o f visible alteration affects, has led some observers to conclude that the barite i s o f sed~mentaryorigin. The term "bedded deposits" has been used i n the literature 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 (1 .

Y e Barite p r o d u c t ~ o nbegan 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 barite in 1909. The Crystal m i n e i n Mineral County was a n active producer from '1916 through 1919, and again during the 1920's and early 1930's. The development of t h e present N e v a d a barite 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 replacement type deposits in the Battle Mountain-Carlin a r e a of Lander, Eureka, and Elko Cow nti e s . , c ‘ (Y I) r r Figure 1. Nevada and U.
