Construction aggregates

Part of a special section on the market performance of industrial minerals in 1992. Production of construction aggregates increased by 4.6 percent in 1992. This increase was due, in part, to the increased funding for transportation and infrastructure projects. The U.S. produced about 1.05 Gt of crushed stone and an estimated 734 Mt of construction...

Fluorspar

The U.S. produced 50 kt of fluorspar in 1992 and imported nearly 409 kt. Almost all the fluorspar was imported from China. The U.S. consumption of 467 kt represents the lowest level since 1958. This is due to the continuing decrease in consumption by the steel and aluminum industries.

Strontium

Part of a special section reviewing the market performance of industrial minerals in 1992. Imports of celestite (strontium ore) reached nearly 45 kt, which represents an increase of 35 percent over 1991. Mexico supplied almost all of the celestite. Nearly 70 percent of the strontium consumed in the U.S. is used in television picture tube faceplate...

Alteration and metallization in the Bagdad porphyry copper deposit, Arizona

The porphyritic to seriate-textured quartz monzonite host-rock at Bagdad was changed by hypogene alteration to a granular rock in which the plagioclase became albitic, orthoclase and quartz increased in amount, and hornblende and book-biotite were recrystallized to pale brown leafy biotite. Hypogene sulfides, pyrite and chalcopyrite, were added...
