Sedimentology: How do lake depositional environments show up on the sedimentary layer of a sedimentary rock?
What about sediment composition? How does that reflect lake depositional environments?
The composition of sediment within a sedimentary rock can give clues as to the source of the sediment and the depositional environment. In lake depositional environments, the sediment is typically composed of fine-grained clays, silts, and organic matter.
