...F. M SWAIN; N PROKOPOVICH Abstract The lake and bog deposits of Cedar Creek Forest, Isanti and Anoka counties, Minnesota, consist of a multiple-facies accumulation of marl, peat, copropel, and sapropel. Chromatographic analyses of the lipoid extracts of samples of the sediments show measurable...

Internal standing waves are believed to have been important in the distribution of the copropelic sediment. Lipoid extracts of some of the sediments were...

..., where they are diluted by ground waters. The quartzite of the deposit has been for a long time a matter of disputes, being variably interpreted as sedimentary Triassic quartzite affected by recrystallization (e.g., Lipoid, 1867; Szabó, 1891), or hydrothermal metasomatic quartzite (e.g., Böckh, 1901...

... of kerogen was shown to depend on lipid and lipoid content, other conditions being equal. The higher lipid and lipoid content, the more H is contained in OM. Most samples from the Molodo River section are of humoid–lipoid type, according to the OM classification by O.A. Radchenko and V.A. Uspenskii (1972...
