Tourmaline and associated minerals from the Himalaya mine, Mesa Grande, San Diego County, California.
The Himalaya dike system in the Mesa Grande district of San Diego County, California consists of several relatively thin and remarkably continuous pegmatites that crop out along the east and north flanks of Gem Hill. The Himalaya mine is the northernmost and historically the most productive of three

INTRODUCTION Namibite, Cu[(BiO).sub.2](V[O.sub.4])(OH),(*) is a rare mineral generally occurring in granitic pegmatite and polymetallic quartz vein settings. It is commonly associated with other bismuth minerals including native bismuth, bismuthinite, bismutite, bismite, beyerite, eulytite, pucherite, schumacherite and clinobisvanite. Since its first ......
