Ranked on their work in Geochemistry and Petrology alone: how many more of their papers here reached the world top 10% for their subfield and year than the 10% expected, among 442,202 ranked researchers with a paper here. Each paper counts once, so many strong papers outrank one famous one, and a long record of ordinary papers does not climb.
