How do you differentiate between deposits in a fluvial environment vs. a marine environment?
How to Answer
- 1
Identify the sediment characteristics: Fluvial deposits are often coarser and better sorted while marine deposits are finer and more uniform.
- 2
Consider the depositional environment: Fluvial systems have channels and floodplains, marine systems have continental shelves and deep-sea settings.
- 3
Look for biogenic content: Marine deposits often contain marine fossils, while fluvial deposits may contain terrestrial plant remains.
- 4
Examine stratification: Fluvial deposits show cross-bedding due to flowing water, while marine deposits usually have smooth lamination.
- 5
Assess mineral composition: Fluvial environments may have more varied minerals from terrestrial sources, whereas marine sediments often include calcite and silicate minerals.
Example Answers
Fluvial deposits are typically distinguished by their coarse grains and better sorting, with features like cross-bedding due to fast-flowing water. Marine deposits are finer, more homogeneous, often containing marine fossils.
Explain the rock cycle and how igneous, metamorphic, and sedimentary rocks transform.
How to Answer
