Book excerpt: The long-term stability of nuclear waste form borosilicate glasses can be evaluated by understanding the processes that effect the long-term alteration of glass and by comparing laboratory alteration of synthetic basalt and borosilicate glasses with the observed stability of naturally occurring basaltic glasses in diverse geologic environments. This paper presents detailed electron microprobe analyses of naturally altered basaltic glasses (with maximum ages of 10,000 to 20 million years) from low-temperature environments. These results are compared to laboratory data on the corrosion of a synthetic basaltic glass in MCC-1 tests (90°C, a SA/V of 0.1 cm−1 and time periods up to 182 days), MCC-2 tests (190°C, a SA/V of 0.1 cm−1 and time periods up to 210 days) and hydration tests in saturated water vapor (240°C, an estimated SA/V of approx. 106 cm−1 and time periods up to 63 days). Additionally, laboratory-induced hydration alteration of synthetic basalt and borosilicate glasses is compared. These preliminary experiments provide evidence that the alteration processes observed for natural basalt glasses are relevant to understanding the alteration of nuclear waste glass, as both appear to react via similar processes. 12 references, 6 figures, 1 table.

Available in PDF, EPUB and Kindle. Book excerpt: The subsurface microbial biosphere in the igneous oceanic crust has implications for global geochemical cycling, early life on Earth, and the search for life on Mars. Microscopic evidence of a subsurface microbial ecosystem includes biotic alteration textures associated with basaltic glass. The exact conditions in the basaltic layer that make this a viable ecosystem remain unknown. Geologic investigations rely on the principle that the present is the key to the past and therefore the conditions evident in rocks today can be used to elucidate conditions occurring over time. The application of this principle to basaltic rocks sampled from the modern ocean containing biotic alteration textures is the primary objective of this study. This study is a global investigation into the relationship between the morphology of biotic alteration and its abundance in the ocean crust and the environmental conditions associated with the host rocks. The Ocean Drilling Program and the Deep Sea Drilling program provided subseafloor basaltic glass samples used in this study. The unique morphologies of the biotic alteration textures present were identified using a classification system and the abundance of biotic alteration was estimated as a percent of the total alteration present in the samples. Nine distinctive textures were selected for correlation with five environmental parameters including sample age, sample depth in basalt, overlying sediment thickness, temperature, and secondary mineralogy. These parameters served as proxies for the environment associated with biotic alteration such as oxidizing conditions, fluid flow, pH, and temperature tolerances for microbial growth. Preliminary results indicated the abundance and the frequency of biotic alteration textures varied with the environmental conditions. Statistical analyses were conducted to assess the strength and direction of the variation between the biotic alteration and environmental parameters. I found that several biotic alteration textures and biotic alteration abundance had statistically significant correlations with sample age, sample depth into basalt, temperature, and some secondary minerals. The subseafloor biosphere is a complex environment influenced by many variables. This investigation into how the evidence of biotic alteration preserved in basaltic glass varies with the environmental conditions represents a step towards understanding the dynamics of the ecosystem in the ocean crust.
