Enthalpy of formation of ye’elimite and ternesite

Calcium sulfoaluminate clinkers containing ye’elimite (Ca4Al6O12(SO4)) and ternesite (Ca5(SiO4)2SO4) are being widely investigated as components of calcium sulfoaluminate cement clinkers. These may become low energy replacements for Portland cement. Conditional thermodynamic data for ye’elimite and ternesite (enthalpy of formation) have been determined experimentally using a combination of techniques: isothermal conduction calorimetry, X-ray powder diffraction and thermogravimetric analysis. The enthalpies of formation of ye’elimite and ternesite at 25 °C were determined to be − 8523 and − 5993 kJ mol−1, respectively

Genetic Applications in Avian Conservation

A fundamental need in conserving species and their habitats is defining distinct entities that range from individuals to species to ecosystems and beyond (Table 1; Ryder 1986, Moritz 1994, Mayden and Wood 1995, Haig and Avise 1996, Hazevoet 1996, Palumbi and Cipriano 1998, Hebert et al. 2004, Mace 2004, Wheeler et al. 2004, Armstrong and Ball 2005, Baker 2008, Ellis et al. 2010, Winker and Haig 2010). Rapid progression in this interdisciplinary field continues at an exponential rate; thus, periodic updates on theory, techniques, and applications are important for informing practitioners and consumers of genetic information. Here, we outline conservation topics for which genetic information can be helpful, provide examples of where genetic techniques have been used best in avian conservation, and point to current technical bottlenecks that prevent better use of genomics to resolve conservation issues related to birds. We hope this review will provide geneticists and avian ecologists with a mutually beneficial dialogue on how this integrated field can solve current and future problems

The geology of part of the Adelaide Series rocks in portions of the Hundreds of Barossa and Moorooroo.

This item is only available electronically.In the area survey, the rock formations are mainly Adelaide Series rock which belong predominantly to the lower Adelaide System in age. Several major faults have been found in the area as well as a number of minor faults and belts of intense drag folding. A major fault extending from Williamstown to Rosedale is approximately parallel in strike with the regional cleavage. The vertical displacement is several thousand feet. Injection of pegmatites took place in the zones of intense faulting and folding and under the high temperatures prevailing talc was formed through metasomatic processes and accumulated in drag folds; clay and damourite were formed under hydrothermal conditions and an introduction of iron-ore in fault zones of the Mt. Kitchener area (this must not be confused with the Mount Bessemer iron ores). According to Sprigg, middle Tertiary Time was a period of faulting (Kosciusko Epoch) in which the present 'Horst' Range took place. The writer considers that the down faulting of the Tanunda Angaston Senkungsfeld corresponds to this period. The older rocks, although much covered by Tertiary sands, clays and gravel beds, and in places lateritized (see Diagram) to a white clay, which is evidence of much secular decay, shows evidences of much folding and served faulting and considerable thermal and metamorphic changes. From Barritt's Estate (north Para) a fault zone runs down to the foothills at Williamstown. This fault is probably of middle Cambrian age when pegmatites were injected into fracture zones during orogenic events. This injection of pegmatites was accompanied by wide spread hydrothermal alteration with development of talc, chrysotile, serpentine, sericitic mica. The marble horizon above the basal grits can be traced across the area occupied by Tertiary sands and gravels in the Lyndock area, mainly from bore results. Between Rosedale and Mr. Hermann Thunn's Winery, the limestones are deposed in the form of an anticlinal fold. The presence of quartzite beds have prevented intense faulting and folding of the less competent strata except in fault zones and these quartzite bands have been found a useful index to the regional dip. Mineralization does not generally occur on a commercial scale in the area surveyed. Copper ores occur at the Enterprise Copper mine and the Lord Lindock mine. However, these have been practically worked out. Rutile occurs as disseminations in damourite schists and clay occurs in important deposits at Williamstown. Gold has been found in many places in the Tertiary gravels.Thesis (B.Sc.(Hons)) -- University of Adelaide, School of Earth and Environmental Sciences, 194
