Micropaleontoloty application

Came across this blog post this afternoon. An application of SEM to a field I am not terribly familar with. Using forams for dating is an interesting concept that I know next to noting about and is yet another application of SEM to geoscience.

An excerpt from the post:

Forams are microscopic plankton, and they leave a calcium carbonate shell behind when they die. When people go out on the IODP legs, one thing they use Foraminfera for is to date the layers of sediment that they are drilling. To make their identifications we need good reference pictures to see what the minute details of these shells are, what they texture of their shell wall is, etc.
