文摘

Biogenic aggregates had higher TOC and TN content as compared to physicogenic. PS and DL increased 15N in biogenic and physicogenic as compared to control. Physicogenic aggregates had higher 15N values as compared to biogenic. PS and DL increased TOC and TN in biogenic aggregates compared to physicogenic. PS and DL increased biogenic formation pathway as compared to physicogenic.
