After gaining undergraduate and master's degrees at Queen's University Belfast in 1952 and 1953 respectively, Emeleus went to work with Bill Wager at Oxford, where he was a student at Wadham College, Oxford. He graduated with a PhD in 1957. During this period he was introduced to the layered igneous rocks of Greenland and Rùm, where he initially worked with George Malcolm Brown.
In addition to his teaching and research into igneous rocks, Emeleus was a highly capable petrologist. 
The mineral emeleusite, a colourless sodium silicate, is named after him.
