Fossil creation from small-scale oxygen limitation in sediments - building a model
What is it about?
The traditional view of sediment, is as a system who's chemistry and biology steadily changes with depth. Little consideration was given to localised biology/chemistry that differed from what was expected at that depth. This study involved the development of a model that allows us to predict what happens when highly reactive organic matter micro-environments occur in sediments.
Why is it important?
This is important as the existence of these environments could alter our view of how sediments are formed and layered and how organic matter is preserved - and ultimately fossilised. This also shows a route where dead organisms could be changed into pyrite and preserved in the sediment - even in oxygenated sediment where they would not be predicted to exist.
