Expertise
Rafael started his research career investigating the relationship between the breakup of the supercontinent Pangea and global climates with an 40Ar/39Ar geochronologic study of the Paraná-Etendeka Large Igneous Province in South America. In 2016, Rafael transitioned to research the origin of orogenic gold deposits in Brazilian greenstone belts, spending three years working as an exploration geologist. He has also worked as a as a Mineral Development Analyst for the federal government (Crown-Indigenous Relations and Northern Affairs Canada). Rafael is currently completing his Ph.D. at Carleton University, examining the effects of mafic intrusive rocks on base metal sediment-hosted deposits in the Central African Copperbelt. Rafael joined the Survey in 2023.
