Sedimentology of Caliche (Calcrete) Occurrences of the Kirşehir Region
Mineral Res. Expl. Bull., 120, 69-80, 1998 SEDIMENTOLOGY OF CALICHE (CALCRETE) OCCURRENCES OF THE KIRŞEHİR REGION Eşref ATABEY*; Nevbahar ATABEY* and Haydar KARA* ABSTRACT.- Study was conducted in the Kırşehir region. Carbonate occurrences within the upper Miocene-Pliocene deposits forming the subsidence basins surrounded by the Kırşehir massive, are described as caliche. These caliche deposits in the alluvial fan-meandering river and lacustrine environments are found in three different zones. In the measured, sections, conglomerate comprises the basement and is overlain by a transition zone made of sandy mudstone (Zone I). Above them is the rarely nodular carbonaceous zone with horizontal and vertical positions in the reddish mudstone-siltstone (Zone II). Finally, laminated caliche (calcrite) comprises the upper most part (Zone III). Carbonates in the basement, country rocks, and in the soil are dissolved in the acidic environment and become a solution saturated with calcium bicarbonate. This solution is transported to the sediments and capillary rises through the sediments during arid-semi arid seasons. Carbondioxide in the Ca and HCO3- bearing solution is removed from the system and as a result, calcium carbonate nodules and laminated caliche are formed. These stromatolite-like laminated caliche occurrences show a criptoalgal structure under polarized microscope and scanning electron microscope (SEM), and they contain microerosional surfaces and caliche pisolites that are formed by dissolution. Caliche occurrences are believed to be source of camotite, thorium, vanadium, sepiolite, huntite, dolomite, and magnesite.

Long Term Atmospheric Deposition As the Source of Nitrate and Other Salts in the Atacama Desert, Chile

Modeling of atmospheric processes indicates that the ⌬17O signatures are the result of photochemical reactions in the troposphere and stratosphere. We conclude that the bulk of the nitrate, sulfate and other soluble salts in some parts of the Atacama Desert must be the result of atmospheric deposition of particles produced by gas to particle conversion, with minor but varying amounts from sea spray and local terrestrial sources. Flux calculations indicate that the major salt deposits could have accumulated from atmospheric deposition in a period of 200,000 to 2.0 M years during hyper-arid conditions similar to those currently found in the Atacama Desert. -

Growing Plants in Caliche Soils
Growing Plants in Caliche Soils Guide A-151 John Idowu and Robert Flynn1 Cooperative Extension Service • College of Agricultural, Consumer and Environmental Sciences INTRODUCTION Caliche is a whitish-gray or cream-colored soil layer that has been cemented by carbonates of calcium and magnesium. Caliche may occur as a soft, thin soil horizon (layer); a hard, thick bed; or a layer exposed to the surface by erosion (SSSA, 2001). Many soils of arid and semiarid regions, including New Mexico, have caliche layers (Figure 1) under the surface, and these layers may vary in thickness. Previous studies conducted in New Mexico show that caliche can have different physical properties, and different types of caliche layers can be found in the same field (Gile, 1961). For example, some caliche materials are very hard to break (strongly in- durated or hardened; Figure 2) while some are rela- tively easy to break (slightly indurated; Figure 3). Figure 1. Caliche rock fragment from Tularosa, NM The very hard caliche layers normally pose more (photo by Robert Flynn). problems for agricultural uses than those that are easy to break. Non-indurated caliche (sometimes referred to as “soft” caliche; Figure 4) does not pose a problem for root growth and development, but can impose some nutrient-related issues for crop growth because of pH and the presence of bicarbonates. Caliche layers are formed when carbonates in the soil are dissolved and leached by rainwater. The water then rapidly evaporates or is removed by plants, leaving the carbonates behind. The carbon- ates bind with other soil particles (such as sand, clay, or silt) and become hardened caliche deposits (Hennessy et al., 1983). -

The test is being conducted to meet the requirements of Hanford Federal Facility Agreement and Consent Order (Ecology et al. 1989) Milestone M-045-20, and is described in the 200 West Area Tank Farms Interim Measures Investigation Work Plan (RPP-PLAN-53808 2013). To support the design of the test, numerical simulations were conducted to help define equipment and operational parameters. The modeling effort builds from information collected in laboratory studies and from field characterization information collected at the test site near the Hanford Site 241-SX Tank Farm. Numerical simulations were used to evaluate pore-water extraction performance as a function of the test site properties and for the type of extraction well configuration that can be constructed using the direct-push installation technique. Output of simulations included rates of water and soil-gas extraction as a function of operational conditions for use in supporting field equipment design. The simulations also investigated the impact of subsurface heterogeneities in sediment properties and moisture distribution on pore-water extraction performance. -

The clay mineral assemblage of the lowest part is dominated by montmorillonite (Zone I); above is a zone of progressive upward in- crease of attapulgite (Zone 2); and above this, a thin zone dominated by sepiolite and attapulgite (Zone 3). Zones 1 through 3 are interpreted as representing progressive desiccation through Pliocene time. At the top of the formation, above Zone 3, are two thin zones characterized by abundant carbonate. Zone 4 is again dominated by montmorillonite with lesser amounts of illite and kaolinite, but no attapulgite or sepiolite. -
Street Art Of
Global Latin/o Americas Frederick Luis Aldama and Lourdes Torres, Series Editors “A detailed, incisive, intelligent, and well-argued exploration of visual politics in Chile that explores the way muralists, grafiteros, and other urban artists have inserted their aesthetics into the urban landscape. Not only is Latorre a savvy, patient sleuth but her dialogues with artists and audiences offer the reader precious historical context.” —ILAN STAVANS “A cutting-edge piece of art history, hybridized with cultural studies, and shaped by US people of color studies, attentive in a serious way to the historical and cultural context in which muralism and graffiti art arise and make sense in Chile.” —LAURA E. PERÉZ uisela Latorre’s Democracy on the Wall: Street Art of the Post-Dictatorship Era in Chile G documents and critically deconstructs the explosion of street art that emerged in Chile after the dictatorship of Augusto Pinochet, providing the first broad analysis of the visual vocabulary of Chile’s murals and graffiti while addressing the historical, social, and political context for this public art in Chile post-1990. Exploring the resurgence and impact of the muralist brigades, women graffiti artists, the phenomenon of “open-sky museums,” and the transnational impact on the development of Chilean street art, Latorre argues that mural and graffiti artists are enacting a “visual democracy,” a form of artistic praxis that seeks to create alternative images to those produced by institutions of power. Keenly aware of Latin America’s colonial legacy and Latorre deeply flawed democratic processes, and distrustful of hegemonic discourses promoted by government and corporate media, the artists in Democracy on the Wall utilize graffiti and muralism as an alternative means of public communication, one that does not serve capitalist or nationalist interests. -

La última década del siglo XX se caracterizó por la consolidación de la nueva fase de internacionalización de los mercados, que pone en dependencia recíproca a las naciones en un grado que no tiene precedentes en el pasado. Dentro de ese marco global, en al año 1991 nace el MERCOSUR. Este bloque económico surge como una respuesta natural de los socios comerciales de la región frente a la creciente regionalización que se verifica en el resto del mundo. Se eligió la integración como modo de posicionarse como región, frente a los otros bloques económicos del mundo globalizado, tales como la Unión Europea (UE) y el Tratado de Libre Comercio de América del Norte (TLCAN o NAFTA) En Junio de 1996 se firmó el Acuerdo de Complementación Económica MERCOSUR, Chile sentó las bases de ampliación del espacio económico con una zona de libre comercio, facilitación del transporte sobre todo terrestre, a través del Corredor Bioceánico, para favorecer la libre circulación de bienes y personas, la defensa de la competencia y del consumidor, la doble imposición internacional, la propiedad intelectual y la cooperación científica tecnológica.
