The Quaternary Geology of the Eastern Side of the Greys River Valley and the Neotectonics of the Greys River fault in Western Wyoming

Allen Jones, L. C. 01 May 1995 (has links)
The Greys River fault is the easternmost active normal fault associated with Basin and Range extension in the lntermountain seismic belt. It is a north south trending normal fault, located in the Sevier-age fold and thrust belt of western Wyoming , and bounds the west side of the Wyoming Range . The fault is at least 54 km long , and juxtaposes Permo-Pennsylvanian Wells Formation against various Triassic formations . Throw ranges from 100-1000 m. Seismic reflection data suggest that the Greys River fault is a listric normal fault that soles into the Darby thrust at depth. The fault offsets late Quaternary deposits on the west flank of the Wyoming Range. These deposits were mapped and differentiated on the basis of provenance and weathering characteristics. Four sets of moraines were identified in the study area. The moraines segregated into a local four-fold relative age sequence based on topographic position and relative dating parameters. The four-fold relative age sequence was correlated to Blackwelder's original Rocky Mountain glacial chronology. The most extensive glacial deposits were correlated to the late Pinedale glacial advance. Alluvial deposits associated with the Pinedale glacial cycle also contain evidence for late Quaternary faulting on the Greys River fault. Maximum vertical surface displacements of late Quaternary deposits range from 8.6 m in Blind Bull Creek to 8.3 m in Box Canyon, 25 kilometers to the south. Between these points, vertical surface offset ranges from 3 to 8.2 meters. Three trenches were excavated in a late Pinedale alluvial terrace complex in Sheep Creek across a 7.5-meter scarp, a 3.1-meter scarp, and a 7.5-meter scarp-graben. The trenches revealed evidence for two paleoseismic displacements, the ages of which were constrained by eight radiocarbon dates. The most recent event involved a maximum displacement of 4.5 meters and occurred between 2110 +/- 60 and 2910 +/- 60 14C years BP. The earlier event was associated with a maximum observed displacement of 3.2 meters and occurred between 5080 +/- 60 and 5310 +/- 60 14C years BP. The moment magnitudes for these events, calculated from displacement and surface rupture length , range from Mw = 6.9 to 7.4 for both events. Scarp heights indicate an uplift rate of 1.11 mm / year. If the late Pinedale alluvium is 14,000 years old, then it appears no events occurred between 14,000 yr BP and 5310 14C yr BP, and two events have occurred between 5310 14C yr BP and 2110 14C yr BP. Such irregular recurrence interval is typical for normal faults in the Basin and Range and makes long-term prediction difficult.

Geração de resíduos sólidos de galvanoplastia em regiões densamente povoadas - avaliação, inertização e destinação / Production of solid galvanic waste in densely populated areas evaluation, inertization and disposal

Mattos, Cleiton dos Santos 15 March 2011 (has links)
Os resíduos sólidos galvânicos despertam especial atenção, devido à sua composição tóxica. Tais resíduos geralmente são estocados nas empresas de galvanoplastia, criando um preocupante passivo ambiental, em particular, nas áreas densamente povoadas, como a zona leste da cidade de São Paulo, que, por sua vez, possui um pólo de empresas de galvanoplastia do setor de cromação. Face ao pressuposto, na primeira parte do trabalho, um estudo foi realizado com a compilação dos dados de empresas galvânicas situadas na zona leste de São Paulo, abordando aspectos socioeconômicos e de processo, que influenciam na geração e na destinação dos resíduos sólidos industriais. Na segunda parte do trabalho, amostras selecionadas de resíduos sólidos foram avaliadas quanto às suas características químicas e físico-químicas e foi apresentada a viabilidade do uso tecnológico visando o aproveitamento destes resíduos. Os principais resultados obtidos mostraram que nas dezessete empresas visitadas são geradas 106 toneladas de resíduos sólidos por ano e estes são armazenados em condições precárias, podendo afetar a população vizinha em caso de acidentes ambientais. Os resíduos constituídos majoritariamente por Ni, Cr, B, Cu, Ca, S, C, Na, Fe e Zn, quando aquecidos até 1400°C, apresentaram formações de compostos identificados como Ca2Cr2O5, BaCrO4, NiCr2O4, CuCrO2, CaSO4, Ni2SiO4, NiO e CuO. Estes compostos são difíceis de serem obtidos e, por si só, apresentam potencial para comercialização como matérias-primas para a produção de produtos cerâmicos. Os resíduos sólidos galvânicos foram incorporados em matrizes vítreas, indicando uma alternativa satisfatória e de baixo custo para a inertização dos constituintes nocivos à saúde. Os vidros obtidos apresentaram aspectos coloridos, podendo ser utilizados como produtos finais ou como matérias-primas para a produção de esmaltes cerâmicos ou pigmentos inorgânicos. Existem diversas possibilidades de destinação dos lodos galvânicos e, independente de qual seja adotada, conclui-se que é de extrema importância a sua retirada de dentro das empresas, para eliminar o enorme e crescente passivo ambiental. / Solid galvanic waste has attracted special attention due to its toxic composition. These wastes are usually stored in galvanic companies, creating a worrying environmental liability, especially in densely populated areas, as eastern side of São Paulo city, which area has many galvanic companies of chroming sector. Therefore, on the first part of this research, a study was made with the collection of informations of the galvanic companies situated on the eastern side of São Paulo, considering the socioeconomics aspects and process, which interfere on the destination and generation of the industrials solid waste. On the second part of the research, selected samples of the solid waste were analyzed related to its chemical and physical-chemical characteristics and it was showed the viability of technological using viewing the utilization of this waste. The main results show that in the seventeen companies visited, 106 tons/year of solid waste have been produced and being stored in precarious conditions, may affecting the neighbor population in case of environment accidents. The waste mainly composed of Ni, Cr, B, Cu, Ca, S, C, Na, Fe and Zn, when heated up to 1400°C, showed compounds formations identified such as Ca2Cr2O5, BaCrO4, NiCr2O4, CuCrO2, CaSO4, Ni2SiO4, NiO and CuO. This compounds are difficult to obtain and are economically important as raw materials for the ceramic products production. The solid galvanic waste were incorporated into the glassy matrix, indicating that this technique is a good alternative and with low cost for the inertization of these chemical compounds, which are harmful to the health. The glasses are colorful, and can be used as final products or as raw materials for the production of ceramic enamel or inorganic pigments. There are many possibilities of destination of the galvanic waste and, independent of which one is adopted, it may be concluded that is of extreme importance to take it out of the companies, to eliminate the enormous and growing environmental liability.

Polyfunkční dům / Multi-purpose building

Kopr, Radim January 2019 (has links)
The diploma thesis deals with the design of a multifunctional house on the street Křídlovická in the city of Brno. The new building is five-storey with four above-ground and one underground floors. The main entrance is oriented to the southeastern side and adjacent to the northwest side, and a separate entrance to the underground garage in the southwest corner of the designed object. Behind the main entrance is a staircase connecting all floors, after a special entrance for the underground garage is the staircase down into the garage. From the southwest side there are entrances to restaurants and shops, these have staffing and supply entrances and social facilities from the north-east side of the building. A downhill ramp is also located behind the northeast side of the building, from the southwest side are solved areas - restaurant garden, sidewalks and parking areas. In other above-ground floors, open space office spaces with separate meeting rooms, office director, secretary offices, and social facilities on the northeastern side of the floor are designed. Within these floors is proposed continuous greening of the atrium. The supporting system is a monolithic reinforced concrete combined with masonry staircases and a northeast wall. In the basement, the support system is a skeleton in combination with the walls of a lost formwork. Roof flat single-skinned with various inclinations 1-5°
