Ralph J. Roberts Distinguished Lecture Series
In 1995 Ralph Roberts made a donation to the Mackay School of Mines with the intent of starting a lecture series in economic geology that would complement the CREG program. Ralph Roberts, a pioneering geologist formerly with the U. S. Geological Survey , is credited with pointing out the potential for carbonate-hosted disseminated gold deposits in what is now the Carlin Trend. Lectures are typically given in late April or early May on UNR’s campus.
Jean Cline, economic geology professor from the University of Nevada Las Vegas giving the nineteenth Ralph J. Roberts Distinguished Lecture in Economic Geology in 2013.
