Fossil pigments in Minnesota lake sediments and their bearing upon the balance between terrestrial and aquatic inputs to sedimentary organic matter

Eville Gorham, Jon E. Sanger

Research output: Contribution to journalArticlepeer-review


Comparison of pigment concentrations in sedimentary organic matter with those in potential source materials indicates that the major inputs to profundal sedimentary organic matter in Minnesota lakes are aquatic. It seems likely that terrestrial inputs are of considerable importance only in the relatively unproductive northeastern lakes with the lowest concentrations of sedimentary pigments. (Waelti-Minn)
