The Calcite Veins of the Livingston Formation

An interesting group of calcite veins occur near Livingston Montana in a zone about eight miles wide and forty miles long in the edge of the Plains region of Montana in front of the Main ranges. The zone extends from the Boulder River south of Big Timber, through Springdale and Hunters Hot Springs, to Potter's Basin just north of Wilsall in Park County. The group of veins is particularly interesting because they cut relatively flat lying strata, suggest a structural relation­ship to one another, and they are nearly pure calcite. The present investigation was to determine the position of the calcite veins by plotting them on a base map of the district. In addition, it was planned to determine the mineralogy end origin of the veins and their structural and stratigraphical relationship to the rocks of the Livingston formation which they cut.

Elisabeth de Austria : la mirada de una emperatriz de incógnito

Elísabeth de Austria (1837-1898) no pudo escapar a su destino de emperatriz y reina, pero eso no la detuvo en la búsqueda de la libertad que anhelaba y que desató la crítica de la sociedad vienesa. La artifícialidad y los intereses cortesanos tan diferentes a los suyos, hicieron que escapara cada vez más lejos y durante más tiempo. A los 22 años, seis después de su matrimonio, luego de haber dado a luz al heredero, y por una serie de desavenencias con su marido, comenzó la búsqueda de su individualidad y ya no se detuvo. Madeira, Corfú, Venecia, las termas de Austria y Alemania, su amada Hungría, las ruinas de Grecia y la pasión por los lugares que vieron al legendario Aquiles la llevaron de uno a otro lado. La escritura de sus poemas comenzó cuando ya casi contaba 50 años, y por cuatro años consecutivos llevó un Diario Poético que quedó inconcluso cuando su hijo fue encontrado muerto en Mayerling. Son poemas que denuncian la caducidad de la monarquía, la corrupción de la corte, la falta de amor y comprensión, y que logran su efecto cuando Elísabeth describe los lugares que la conectan con la naturaleza del mundo.

Lithium and strontium isotopic compositions of sediments and pore waters at ODP Sites 152-918 and 152-919

The distribution of Li isotopes in pore waters to a depth of 1157 m below seafloor is presented for ODP Sites 918 and 919 in the Irminger Basin, offshore Greenland. Lithium isotope data are accompanied by strontium isotope ratios to decipher diagenetic reactions in the sediments which are characterized by the pervasive presence of volcanic material, as well as by very high accumulation rates in the upper section. The lowering of the 87Sr/86Sr ratio below contemporaneous seawater values indicates several zones of volcanic material alteration. The Li isotope profiles are complex suggesting a variety of exchange reactions with the solid phases. These include cation exchange with NH4+ and mobilization from sediments at depth, in addition to the alteration of volcanic matter. Lithium isotopes are, therefore, a sensitive indicator of sediment-water interaction. d6Li values of pore waters at these two sites vary between -42 and -25?. At shallow depths (<100 mbsf), rapid decreases in the Li concentration, accompanied by a shift to heavier isotopic compositions, indicate uptake of Li into alteration products. A positive anomaly of d6Li observed at both sites is coincident with the NH4+ maximum produced by organic matter decomposition and may be related to ion exchange of Li from the sediments by NH4+. In the lower sediment column at Site 918, dissolved Li increases with depth and is characterized by enrichment of 6Li. The Li isotopic compositions of both the waters and the solid phase suggest that the enrichment of Li in deep interstitial waters is a result of release from pelagic sediments. The significance of sediment diagenesis and adsorption as sinks of oceanic Li is evaluated. The maximum diffusive flux into the sediment due to volcanic matter alteration can be no more than 5% of the combined inputs from rivers and submarine hydrothermal solutions. Adsorption on to sediments can only account for 5-10% of the total inputs from rivers and submarine hot springs.

(Table 1) Experimental results of Kd at various conditions from ODP Hole 131-808C

A comprehensive experimental study, utilizing a rocking autoclave hydrothermal apparatus with isotope tracers, was applied to evaluate the temperature of squeezing artifacts on B contents and isotopic compositions in pore waters. The partition coefficient (KD) was determined at temperatures from 25 ° to 350 °C, at 800 bars, and this information was applied to reconstruct pore water B and d11B in ODP drill sites, where pH, T, and porosity are known. The partition coefficient of B is a function of temperature, pH, and sediment mineralogy. The solution pH exerts a dominant control at low temperatures; however, KD decreases to a value of essentially zero (compared to that of KD = ~3.5 at 25 °C) at high temperatures indicating no adsorption. Two empirical equations were derived to represent most of the available experimental results. For pelagic clay rich sediments, a KD = -3.84-0.020T + 0.88pH (R = 0.84; 1sigma = 0.25) is established. For sediments that have experienced progressive metamorphism, a KD = -1.38-0.008T + 0.59pH (R = 0.81; 1sigma = 0.37) can be applied. Similarly the effect on pore water d11B can be corrected if the fractionation factors at different temperatures are assumed. The corrected B and d11B in ODP Sites 671, 672, and 808 indicate significant mobilization of bulk B in sediment (exchangeable + lattice bound) at depth, especially near the décollement zone or other potential flow conduits. Tectonically expelled fluids from mud diapirs of Barbados Ridge Complex, hot springs of Rumsey Hills, California, and mud pot waters of the Salton Sea geothermal field, are enriched in B (up to 20 mM) with lower d11B, supporting the argument of B mobilization as a result of fluid expulsion in accretionary prisms.

Integration of Sustainable Development Principles into a Community Park

Characteristics of six operating hot spring recreational facilities were reviewed to identify opportunities for integrating a range of sustainable design and operation approaches into a community park. Potential operating cost savings were evaluated for a conceptual landscape project, bathhouse project, and swimming pool project that reduced the use of electricity, natural gas, water, the discharge of water, and solid waste generation. The projects showed a combined cost savings of approximately $40,000 per year by adopting passive solar design, energy efficient lighting, native vegetation, water efficient fixtures, and a natural swimming pool. The greatest potential operating cost reductions were observed for cutbacks in the use of swimming pool water and reductions in natural gas needed for building and swimming pool heating.

Nitrogen metabolism in haloarchaea

The nitrogen cycle (N-cycle), principally supported by prokaryotes, involves different redox reactions mainly focused on assimilatory purposes or respiratory processes for energy conservation. As the N-cycle has important environmental implications, this biogeochemical cycle has become a major research topic during the last few years. However, although N-cycle metabolic pathways have been studied extensively in Bacteria or Eukarya, relatively little is known in the Archaea. Halophilic Archaea are the predominant microorganisms in hot and hypersaline environments such as salted lakes, hot springs or salted ponds. Consequently, the denitrifying haloarchaea that sustain the nitrogen cycle under these conditions have emerged as an important target for research aimed at understanding microbial life in these extreme environments. The haloarchaeon Haloferax mediterranei was isolated 20 years ago from Santa Pola salted ponds (Alicante, Spain). It was described as a denitrifier and it is also able to grow using NO3-, NO2- or NH4+ as inorganic nitrogen sources. This review summarizes the advances that have been made in understanding the N-cycle in halophilic archaea using Hfx mediterranei as a haloarchaeal model. The results obtained show that this microorganism could be very attractive for bioremediation applications in those areas where high salt, nitrate and nitrite concentrations are found in ground waters and soils.
