Microbial Features

Caption

Petrographic thin section made from core sample is shown. This 30 micron thin slice of rock allows a view of the types of features thought to be microbial, such as the layers that fold over themselves in the middle of the sample marked 2534.8'. This demonstrates that the sediment had to have a degree of cohesive stickiness, such as that provided by the presence of microbial mats.
