USGS Work
During World War II Roberts lived in Central America, where he had been sent to discover and conduct fundamental research on strategic minerals. After the war he returned to the United States; for the next 40 years he worked in Nevada and Utah, deciphering the geologic history of major mountain ranges and exploring mineral deposits.
In 1960, Roberts published a lengthy paper that predicted the existence of important mineral-bearing rocks in Nevada. Roberts' research led to the discovery of the Carlin and Cortez-Battle Mountain gold belts. These two mining districts now represent the richest gold region in the United States, and one of the leading gold producing regions of the world.
During the 1970s he spent six years in Saudi Arabia, mapping ore deposits and contributing to the development of the Arabian mining industry. He retired from the USGS in 1981, but continued his mineral exploration in Nevada for over two decades.

Famous quotes containing the word work:
“Freedom of enterprise was from the beginning not altogether a blessing. As the liberty to work or to starve, it spelled toil, insecurity, and fear for the vast majority of the population. If the individual were no longer compelled to prove himself on the market, as a free economic subject, the disappearance of this freedom would be one of the greatest achievements of civilization.”
—Herbert Marcuse (1898–1979)
