K Gold deposits in Utah are most monly associated with quam metalic sulfides; it also occurs alio,! with silver as electrum, or combi! with tellurium, silver, and 2 elements in several telluride minerak and in several rare minerals it forQ compounds with mercury, bismui and chlorine. The ore deposits ol j, state , are classified according 0 ! geologic age, form or genesis. : Mr. Stowe says that Utah's gold oc- i curs in four major types of deposit : replacement (principally in foldedam! ! faulted limestone beds); fissure veins S (mineralized fractures or faultsthaiu. ! cur in rocks of a wide variety i lithologic types and geologic agesi disseminated copper deposits (recovered as a by-product from f per ores); and placers (sires; gravels). J: Placers consist of gold from weather- I ing separated mainly from silver as: S base metal deposits, and concentrate !: by gravity through the action of mom i water. Increased interest in this type ! prospecting throughout Utah haste f generated. Many areas of the state attract ft ! prospector. Numerous river platers S both bench and stream, occur alongfe ? Colorado River and its principa ! tributaries. There are also numeK f localities along the Green River, t LaSal Mountains, the 'Henry '5k tains, near Marysvale, the Binfk ? district, the Oquirrh Range are also;: tractive placer areas. ?
