Abstract
Summary
The development model of oil shale in the 2nd member of the Liushagang Formation in the study area belongs to the phosphorus-controlled algal eutrophication mode of freshwater lakes.In warm and humid climate, nutrient elements mainly including P, Fe, Mo from provenance, providing nutrition for algae blooming. Algal blooming and subsequently microbially reworking enhance the anoxic environment and promote the accumulation of organic matter in the middle-deep lake.
