A SEISMIC REFLECTION STUDY OF A MISSISSIPPIAN MUD-MOUND NEAR ADEN, ILLINOIS

Holguin Macuster, Ruben 01 August 2018 (has links)
In 2011 and 2012 a Vibroseis™ seismic reflection survey, consisting of one westeast and one north-south seismic reflection profile, was conducted near the community of Aden (Hamilton County), Illinois, for hydrocarbon exploration purposes. Previous interpretations of the west-east seismic line (Ranaweera, 2015), as well as drill cuttings (Cantrell, 2011) from a nearby well (Webb #1), indicated the existence of a mud-mound within the Ullin Limestone. This thesis studied the shape and dimensions, as well as the seismic velocity properties, of the Aden mud-mound by re-processing and interpreting the Aden seismic reflection data. The interpretation process was aided by constructing two-dimensional synthetic seismograms from well log data from the nearby Broughton and Johnsonville oil fields, which are known locations of Waulsortian mud-mounds similar to the one inferred to exist at Aden. The results of this investigation indicate that the Aden mudmound has a longitudinal extent of approximately 0.6 miles (0.97 km) wide across the west-east ADEN #1 profile. From north-to-south on the ADEN #2 profile, the feature is approximately 0.7 miles (1.13 km) long. The geologic feature is located within the Ullin Limestone (Lower Mississippian) and is only manifested by the draping of younger strata overlying the mud-mound as observed on the seismic reflection images. Results from the 2D synthetic seismograms indicate that the seismic reflections generated across the known mud-mounds at Broughton and Johnsonville are similar to the seismic reflections seen at the location of the interpreted mud-mound on the Aden seismic reflection data. The presence of the Aden mud-mound is inferred by the draping of overlying strata above the mud-mound. This is interpreted to be caused by the increase in stratigraphic relief at the top of the Ullin, which becomes thicker at the mud-mound locations. Geologic and well log data from drill holes at Aden revealed that the interpreted Aden mud-mound formed in the Harrodsburg Member of the Ullin Limestone. The Harrodsburg is approximately 90 feet (27 meters) thick at Aden but becomes thicker at the location Webb #1 (up to 152 feet) where the mud-mound is located, indicating that the Aden mud-mound is at least 152 feet thick, when measured from the base of the Harrodsburg Member. A study of Root-Mean-Squared (RMS) and interval velocities, derived from sonic and pseudo-sonic log data from wells from the Aden, Broughton, and Johnsonville locations, indicated that RMS and interval velocities from the upper member (Harrodsburg Member) of the Ullin Limestone are higher than RMS and interval velocities present in the lower member (Ramp Creek Member) of the Ullin. Stacking velocities derived from the Aden seismic reflection data matched the RMS velocity values derived from sonic log data from drill holes at Aden with percent differences of less than 5%. This study indicates that stacking velocities at this location are accurate enough (within approximately 5%) to perform velocity studies when well log data from drill holes are not available. Additionally, there were no significant variations in stacking velocity profiles in the Ullin Limestone atthe Aden mud-mound location when compared to stacking velocity profiles derived at CMP locations away from the mud-mound. Likewise, there were no significant variations between RMS and Interval velocity profiles of the Ullin Limestone, derived from wells that were drilled into mud-mound locations at Aden, Broughton, and Johnsonville, and RMS and interval velocity profiles derived from wells that were drilled away from the mud-mound locations. The conclusion of this study is that RMS and interval velocity profiles, as well as stacking velocity profiles from seismic reflection data, are not good indicators for pinpointing the existence and location of carbonate mud-mounds. The best method to identify such carbonate structures is by interpreting their structure observed on seismic reflection records, including the draping effect on shallow reflections above the mudmound as observed in the recorded seismic reflection data, and by analyzing drill cuttings if available.

A Descriptive Analysis of the Morphology of Prairie Mounds in Southern Alberta

Jordan, Dianne, E. 05 1900 (has links)
<p> Prairie mounds from the general area of Foremost-Cypress Hills, Alberta, have been described. Various morphometric parameters, including relative and absolute altitude of the mounds, depth of their central depressions, orientation of breaches in their rims, angle of the bounding slopes, and distribution of surficial stones were measured. Several characteristics of the mounds were found to be widespread. Firstly, the mounds occur in elongate fields that correspond roughly to the 3,000 ft. contour interval. Secondly, surficial stones invariably have their greatest concentration on the rims of the mounds. Also the mounds are frequently separated by interrupted drainage channels. The bounding slopes of the mounds are asymmetrical, with west and north-west slopes being least steep. Interpretation of these morphological observations and a consideration of the various hypotheses of formation proposed in the literature leads to the conclusion that prairie mounds most likely originated by the differential melting of a stagnant ice mass in a manner proposed by Gravenor in 1955, and have subsequently been modified by mass-wasting processes. / Thesis / Master of Arts (MA)

The Agency of Earth on the Site of the Design

Rahimi Bafrani, Raena 13 July 2021 (has links)
Earth as a fundamental aspect of the existing conditions of a site has/can/should have agency in design, both historically and today. The aim of this study is to describe the agency of earth in design as a common premise between the disciplines of architecture and landscape architecture. The thesis question is "how can the earth on site have agency on the design?" Thinking of the physical earth, specifically the topography, as one of the basic structures of the existing conditions, the earth should be taken as the most important condition that both architecture and landscape architecture use and share; both disciplines have to deal with context; they both have to deal with surroundings, and then work within systems that exist around them. As landscape architecture has been incredibly important to civilization throughout history, this project looks at different ways that earth has agency in design through important periods of history, from Greeks to contemporary design. While there are many examples in which designers have worked with the existing topography, there are other cases across cultures where people have drastically altered topography. Thinking about those designs, there are many possible answers to this thesis question from using existing hills to making mountains. This thesis explores the creation of an artificial mound, as a monument to indigenous people, in order to revive the missed parts of the earth and empower the ground. The thesis rethinks the whole ground, protecting the earth by turning excavated soil into an important earthwork. The design is not only about creating an earthwork for people, it also transforms invisible earth into a visible structure. Based on the practices of Native American mound builders, the earthwork stands for the values of diversity and equality in the US, creating a gathering space for all people made of the native earth/soil. / Master of Landscape Architecture / Earth as one of the existing materials of a site constantly affects the process of the design. This study focuses on describing and improving the use and understanding this material shared by the disciplines of architecture and landscape architecture. As landscape architecture has been incredibly important to civilization throughout history, this project looks at different ways that earth has affected design through important periods of history, from Greeks to modern design. Considering many examples in which designers have worked with the current land, there are other cases across cultures where people have changed earth. Thinking about different designs, there are many possible answers to this thesis question from using existing hills to making mountains. This design is an artificial mound as a monument to indigenous people and it is about reviving the missed parts of the earth in order to empower the ground, rethinking the whole earth and protecting it, turning it into an important earthwork that is not only about something for people but also making it into something which in invisible situations it cannot be. Based on the tradition of Native American mound builders, part of this thesis is to affirm the value of diversity and equality in the US, through creating a gathering space for all people that pays special attention to indigenous culture.

Environmental Natural Processes that Achieve Thermal Comfort in Multifamily Buildings in Hot Arid Regions

Moreno, Paola January 2015 (has links)
Buildings, especially in hot climates, consume a lot of energy when people want to be comfortable inside them, which translates to very expensive fees each month. The most innovative response to this problem is renewable energy, that is used, in this case, to run mechanical HVAC systems. Renewable energy is the solution for many problems, but to avoid urban heat islands when using excessive HVAC systems (powered by renewables), and to solve thermal comfort-related problems, there has to be other solution. The major challenge to find it would be to have a change of thinking process. If a building in a hot-arid region uses natural processes to emulate the functions of HVAC systems, and the proper passive strategies, then, it will provide thermal comfort to its users, diminishing the need of a mechanical system. This hypothesis will be carried out by extracting the natural processes found in a specific case in nature, applying them into a building's design, and then simulating its energy efficiency with the adequate software. There will be a comparison of the same proposed building without the natural processes, to have tangible numbers showing that these proposed strategies, in fact, work. With explanatory detailed diagrams and the energy analysis, the hypothesis could be proven correct or incorrect. The significance of this approach relies on the proximity to the natural processes that have been working in different aspects of life since the beginning of time. They have been there all the time, waiting until architects, engineers, and people in general use them, instead of making more new energy-using inventions. By having the numbers from a conventional building and the ones of the proposed building, and the right environmental diagrams, the experiment should be valid. In the near future, there should be more research focused on nature and its processes, in order to be able to reduce the use of mechanical systems, and with that, reduce the energy use and the carbon footprint.

Por uma arqueologia marginal: as ocupações peri-sambaquieiras no entorno do sambaqui da Figueirinha II, Jaguaruna- SC, examinadas através do radar de penetração de solo / Extra mound structures surrounding the Figueirinha II shell mound seen through the GPR

Penna, Tiago Attorre 24 February 2015 (has links)
Este trabalho procurou por evidências das ocupações sambaquieiras para fora dos sambaquis, buscando eventos de ocupação relativos aos concheiros, mas externo a eles em áreas de alta dinâmica sedimentar. Para tanto se consorciou o radar de penetração de solo (GPR) ao sistema de navegação global por satélite (GNSS), funcionando em modo cinemático de tempo real (RTK), em um esforço de sensoriamento remoto em meio a um campo de dunas no Município de Jaguaruna, no litoral de Santa Catarina. Conseguimos, através do sensoriamento, realizar prospecções arqueológicas e encontrar estruturas marginais aos concheiros, previstas em estudos anteriores que apontavam a remobilização de material processados em outras áreas para dentro dos sambaquis. Encontramos, mapeamos, escavamos, descrevemos e amostramos essas estruturas peri-sambaquieiras no entorno do Sambaqui da Figueirinha II de forma a apresentarmos um panorama da distribuição espacial e temporal destas estruturas. / The work presented here searched for evidences of mound builder\'s occupation outside the shell mounds itself, in search of events related to the shell mounds, but external to it in a very dynamic area. We have integrated the GPR and GNSS-RTK technologies in order to take the archaeological research regarding the shell mound cultures outside the mounds, by remote sensing areas in which extensive sand dunes are found in search of evidence regarding the mound builder\'s settlement in the areas surrounding the mounds, which the existence was predicted in previous studies. In this sense, we integrate the technologies and carried out the sensing of the Figueirinha Region in Santa Catarina State. We have found, mapped, excavated, described and sampled the extra-mounds archaeological occurrences surrounding the Figueirinha II shell mound, in order to presenting an overview of the spatial and chronological distributions of such structures.
