During the period from 1948 to 1950 the U.S. Geological Survey conducted a program of field and laboratory research w determine the mode of occurrence of beryllium in non-pegmatitic rocks and mineral deposits as part of the Beryllium Program of the Division of Raw Materials of the U.S. Atomic Energy Commission. Approximately 23 man months were spent in the field collecting samples from 146 localities in 15 states; a total of 680 samples were collected and analyzed for beryllium. Additional samples collected by the Geological Survey. U.S. Bureau of Mines, various state Geological Surveys and other institutions. and private companies were analyzed for beryllium. In total, the beryllium content of 1,238 samples from about 600 localities in the United States is compiled in the final report which is being prepared for publication by the U.S. Geological Survey. The main topics discussed are: uses and properties of beryllium; methods of analysis and mineralogy of beryllium; occurrence of beryllium in igneous, sedimentary and metamorphic rocks, pyrometasomatic and related deposits, vein deposits, and hot spring deposits; the genesis of beryllium deposits; and a description of the deposits examined. This abstract and table 1 summarize the more pertinent economic data. Beryllium is more abundant than arsenic, gold, silver, and molybdenum in the lithosphere, but its chemical and physical properties prohibit its concentration in minerals which are common w large commercial vein and replacement deposits. There are 29 minerals in which beryllium is an essential constituent but of these only beryl, mined from granite pegmatites, is an ore of beryllium., Beryl also occurs disseminated in granites and high-temperature veins. The other 28 minerals occur as rare constituents in syenite and granite pegmatites, granites, and pyrometasomatic deposits. Beryllium, as a trace constituent, has been detected in 49 minerals but recovery of the beryllium requires metallurgical methods as yet unknown.
