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 such a difficult and interesting problem to solve.
