Abstract
At the annual meeting of the Geological Society of America in Boston during late October, Earth's crust came in for close scrutiny. One surprise was its age: Chemical and isotopic evidence suggested the crust formed soon after the planet did. Participants also discussed features of today's crust, including a horizontal slice beneath San Francisco and the possibility that a particular kind of crustal stretching, long envisioned, may not actually take place.
