The dean of the college of physics I'm at studies stromatolites to determine the sun-earth relationship in the ancient past... Stromatolites are caused from microbial life that secretes ferris material (iron) as part of it's metabolic pathway
OpenStudy (quickstudent):

OpenStudy (agreene):
I actually should correct that--the ones he studies are like that, the current ones don't use that pathway... Stromatolites are caused from microbial life that layers biofilm layers
OpenStudy (quickstudent):
