“…Short-chain aliphatic acid anions are common constituents of pore waters associated with Holocene through Paleozoic strata in many geologic settings: (1) associated with hydrocarbon production (Carothers and Kharaka, 1978;MacGowan and Surdam, 1988;Fisher, 1987), (2) anoxic pore waters of Holocene nearshore marine sediments (Parkes and Taylor, 1983), and (3) hydrothermally altered sediments in the actively rifting Guaymas Basin (Martens, 1990). Although the origin of these compounds is commonly attributed to either bacterial metabolism of sedimentary organic matter (Lamar and Goerlitz, 1963) or thermal alteration of organic matter (Carothers and Kharaka, 1978;Eglinton et al, 1987;Lundegard and Senftle, 1987;Barth et al, 1988), they can be produced by other means. For example, in laboratory experiments, permanganate oxidation of complex natural organics or alkaline hydrolysis of ester linkages (Morrison and Boyd, 1973) produce short-chain aliphatic acids.…”

For the first time, short-chain organic acids are described from serpentine-associated interstitial waters. In this geologic setting, formate typically dominates the organic acid assemblage. Within the forearc setting, the organic acids are associated only with unconsolidated serpentine. Their existence may be the result of alkaline hydrolysis of ester linkages in organic matter that has been entrained in the serpentine diapir.Fryer, P., Pearce, J. A., Stokking, L. B., et al., 1992.

This discovery of an aliphatic acid in fluid inclusions prompted us to collect interstitial water samples for organic acid analysis on Leg 125.

“…Regardless of a bacterial, thermal, or chemical mode of origin, the presence of organic acids requires the existence of more complex organic precursors (Lamar and Goerlitz, 1963;Carothers and Kharaka, 1978;Eglinton et al, 1987;Lundegard and Senftle, 1987;Barth et al, 1988;Haggerty and Fisher, 1992). The most likely precursor material for the aliphatic acid anions present in the interstitial waters sampled would be sedimentary organic matter.…”

“…The formation of aliphatic acids can occur biochemically (microbial alteration of sedimentary organic matter), chemically (alkaline hydrolysis of sedimentary organic matter in basic microenvironments associated with the hydrolysis of igneous components), or thermally (thermal maturation of sedimentary organic matter). However, all of these processes require a complex organic precursor (Lamar and Goerlitz, 1963;Carothers and Kharaka, 1978;Eglinton et al, 1987;Lundegard and Senftle, 1987;Barth et al, 1988;Haggerty and Fisher, 1992).…”

Short-Chain Organic Acids in Interstitial Waters from Western Pacific Guyots

For the first time, short-chain organic acids are described in interstitial waters from five guyots in the western Pacific. Acetate and malonate were the only organic acids found in the Leg 144 samples. Acetate is a consistent feature of these interstitial waters and is the only organic acid associated with the pelagic cap sediments. Acetate also dominates the organic acid assemblage when malonate is present in clay deposits overlying the volcanic substrate. The organic acids in the Leg 144 interstitial-water samples are compositionally less diverse but richer in acetate concentration than those recorded in interstitial-water samples from the Mariana, Bonin, and Tonga forearcs and the Tonga backarc.The presence of both ammonium and sulfate and the dominance of acetate in these Leg 144 interstitial waters suggest that organic acids in the midplate guyot setting arise by way of oxidative deamination of sedimentary proteinaceous material.

A literature review of interaction of oxidized uranium species and uranium complexes with soluble organic matter

Organic material is commonly found associated with uranium ores in sandstone-type deposits. This review of the literature summarizes the classes and separations of naturally occurring organic material but the emphasis is on soluble organic species. The main class of materials of interest is humic substances which ars high-molecularweight complex molecules that are soluble in alkaline solution. These humic substances are able to solubilize (make soluble) minerals and also to complex [by ion exchange and (or) chelation] many cations. The natural process of soil formation results in both mineral decomposition and element complexing by organic species. Uranium in solution, such as ground water, can form many species with other elements or complexes present depending on Eh and pH. In natural systems (oxidizing Eh, pH 5-9) the uranium is usually present as a complex with hydroxide or carbonate. Thermodynamic data for these species are presented. Interacting metals and organic materials have been observed in nature and studied in the laboratory by many workers in diverse scientific disciplines. The results are not easily compared. Measurements of the degree of complexation are reported as equilibrium stability constant determinations. This type of research has been done for Mn, Fe, Cu, Zn, Pb, Ni, Co, Mg, Ca, Al, and to a limited degree for U. The use of Conditional Stability Constants has given quantitative results in some cases. The methods utilized in experiments and calculations are reviewed.
