| Depositional environment | Typical biomarkers patterns | Reference example |
|---|---|---|

1 Typical for, but not necessarily restricted to, this depositional environment
2 This might include environments with an anoxic and sulfidic water column that persists into the photic zone, or microbial mats in very shallow water settings that become anoxic within millimeters below the sediment water interface
