... ABSTRACT Lignin phenol, pollen, and diatom analyses were performed on dated sediments (13,533–8993 cal yr B.P.) recovered from Fallen Leaf Lake, California. This multiproxy data set constrains the end of the Tioga glaciation in the Lake Tahoe Basin and reconstructs the response of the region’s...

... compounds that stand between these two: the humins, lignins and kerogens in sedimentary rocks ( Fig. 1 ). These structurally complex organic polymers are derived from buried organic matter, they contain components that are recognizable biomolecules, and their thermal degradation produces most petroleum...

... and stigmasta-3,5-dien-one), as well as lignin degradation compound products (e.g., benzoic acid, vanillin, 4-benzaldehyde, benzenedicarboxilic acids, and hydroxybenzoic acids), are of terrestrial origin. Monosaccharides with dominant α- and β -glucose were identified as possible remnants of cellulose...

... of THM-GC–MS to investigate the fate of DOM in soils. Molecular proxies, including lignin markers, tannin markers, carbohydrates, and fatty acids, were classified into plant-derived and microbial markers. At the beginning of the hydrologic year, associated with the recharge period, the DOM composition...
