In the subsurface faults can act as both barriers and conduits for fluids or gases such as CO2, hydrocarbons, or water. It is often thought that faults in porous rocks such as sandstone are barriers to fluid flow. In this study we show that this is not always the case. In sandstones like the Cedar Mesa Sandstone it is very important to understand the relationships between this history of fault slip and fluid flow. Better understanding of how fluids migrate through faults and the damaged areas surrounding these faults has strong significance to the oil and gas industry. In this study we examine a group of faults and their surrounding damage zones near Hite, Utah. We analyze three of these small-scale faults in more detail. In doing so we give insights into how these faults and their damage zones can effect fluid migration as well as the porosity and permeability in the Cedar Mesa Sandstone. Whole rock geochemistry, X-ray diffraction mineralogy, permeability data, petrography, ultraviolet photography, and outcrop observations were used to gain insights into cross-cutting relationships, past fluid compositions, and fault characteristics. From the data that was collected from these faults we have begun to describe a series of structural and fluid flow events. This series allows us to say that small-scale faults and fractures are features by which fluids can migrate preferentially. In this series of events we isolate two separate phases of movement. The first phase of movement being has a component of shear in which the edges of the fractures are not moving directly apart. This event is accompanied by a fluid flow event the emplaced iron oxide in the fractures and the surrounding formation. The second event is a phase when the faults become reactivated by a stress that created open mode fractures. This second is accompanied by a fluid flow event that has high calcium content and emplaces calcite in the fractures. Throughout this study we give evidence to support this series of movement and fluid events.

Por meio da análise de artigos sobre educação veiculados na imprensa e de missivas escritas pela educadora à correspondentes estadunidenses buscou-se detectar as práticas escolares e os intentos que presidiram a formação da mulher no âmbito dessa instituição. Considera-se que a atuação educacional do colégio à época, cooperou para o processo de divulgação dos princípios de educação da mulher e alcançou ainda o mérito de possibilitar que algumas de suas alunas seguissem a carreira docente, dentro de um movimento de feminização do magistério, vivido no alvorecer do século XIX / Abstract : In Brighter Lighthouse: the College Piracicabano and female education at the end of the nineteenth century, is investigating aspects of the proposed education implanted in that school and the unfolding of pedagogical work done by educator and Methodist missionary Martha Watts during the process of propagation female education in the last decades of 1800, a special between the years of 1881 to 1895. Through analysis of articles on education running in the press and missivas written by the educator to the corresponding Americans sought is detecting the plan which governed the training of women within that institution. It is considered that the educational performance of the college at the time, cooperated to the process of disseminating the principles of education of women and also reached the merit of enabling some of your students follow a teaching career, in a movement of feminisation of the teaching, lived in the dawn of the nineteenth century / Mestrado / Educação, Conhecimento, Linguagem e Arte / Mestre em Educação
