sedimentytan
Sedimentytan is a term found in some speculative discussions within sedimentology to describe a theoretical class of fine-grained, organic-rich deposits formed in low-energy aquatic environments. The name signals a distinct facies, though usage varies and it is not universally standardized.
Formation and composition: Sedimentytan deposits are typically dominated by clay minerals such as illite and smectite,
Depositional settings: These deposits are associated with calm, stratified water bodies—deep lakes, stable floodplains, backbarrier lagoons,
Diagenesis and significance: In early diagenesis, organic matter interacts with pore fluids to form textures unique
