Hey all,
Here's another stromatolite paper. This one is by a friend in my former lab at Riverside. It tries to show that stromatolites from the Gunflint and Biwabik iron formations were iron-oxidizing bacteria and not cyanobacteria using iron isotopes and rare earth elements.

Iron-oxidizing microbial ecosystems thrived in late Paleoproterozoic redox-stratified oceans. Planavsky Noah (2009) Earth and Planetary Science Letters.
