Famed Alberta diamond research carves out a legacy with new mineral namesake | CBC News From the coalfields of northern England to the Arctic snows and the steaming jungles of Brazil, diamond hunter and scholar Graham Pearson has carved a name for himself that now lives on in rock.

New mineral discovered inside deep-Earth diamond now named after Alberta geochemist. Grahampearsonite was discovered more than 300 kilometres below Earth's surface. www.cbc.ca/news/canada/... #geochemistry #AbSci #UAlberta #science #SciChat

Lew Ashwal of U. Witwatersrand died this week. Over decades, his scholarship helped shape modern thinking on magmatic processes and global crustal evolution (from Grant Bybee).

I remember Lew very patiently helping a young geochemist (myself) understand why mountains made of anorthosite were […]

Researchers Have Uncovered a Missing Piece in Life’s Origin Story Deep beneath the ocean’s surface, mineral-rich hydrothermal vents may have hosted a critical chemical reaction that helped spark life on Earth.

Researchers at the University of Alberta report that they may have identified a missing piece in one of science’s biggest questions: how life first began on Earth. scitechdaily.com/researchers-... #astrobiology #geochemistry #AbSci #science #SciChat
