✦ Synopsis

Bull. 53o-K.)--Vanadium occurs at Placerville, Col., disseminated in a dull green sandstone along seams or in veins containing roscoelite, quartz, and pyrite. Carnotite appears as a lining on the joint surfaces. A sandstone of lighter green color owed its color to mariposite, a chromium mica. Near Green River, Utah, carnotite ore is reported to have been shipped containing 2.2 per cent. uranium oxide and 3.8 vanadium oxide. Vanadinite has been found at Los Caballos, New Mexico.
