Journal ArticleDOI
Calcium oxalate: occurrence in soils and effect on nutrient and geochemical cycles.
TL;DR: Whewellite and weddellite, calcium salts of oxalic acid, have been found in the litter layer of several different soils, indicating that oxalate is a major metabolic product of fungi in natural environments.
Journal ArticleDOI
The origin of calcium oxalates on historical buildings, monuments and natural outcrops
TL;DR: In this article, the authors show that the oxalate patina on Roman imperial marble is due to the shallow penetration of the fungi hypae into the rock, and that this phenomenon is not masked by other weathering processes.
Journal ArticleDOI
Predictions of diagenetic reactions in the presence of organic acids
TL;DR: In this article, the role of OAA in fluid-rock interactions is to contribute to the total alteration assemblage but not necessarily to dominate it, except under exceptional circumstances that might include, for example, hydrocarbon contaminant plumes in aquifers, wetland environments, and within hydrocarbon source-rocks.
Journal ArticleDOI
Mercury in the Sediments of the Gulf of St. Lawrence
TL;DR: In the Saguenay fjord, the St Lawrence estuary, and open Gulf of St. Lawrence, total mercury varies with sediment texture and location from 10 to 12 300 ppb (average 386 ppb).
Journal ArticleDOI
Review of occurrences and carbon isotope geochemistry of oxalate minerals: implications for the origin and fate of oxalate in diagenetic and hydrothermal fluids
TL;DR: In this article, the known occurrences of oxalate minerals in deep diagenetic and hydrothermal environments are reviewed and new carbon isotope results are presented that cover, together with previously published data, 22 of 37 known diagenetics ns 22.
