1. Análisis arqueométrico de pigmentos del sitio arqueológico Tambo Colorado por difracción de rayos X sincrotrón
ABSTRACT Despite the exceptional architecture and polychromy of archaeological site of Tambo Colorado, there has been no conservation work or in the architectural structures of raw earth, nor on the surfaces. These jobs require a proper understanding of the state of conservation of the site architecture and the analysis of the materials used. With this purpo

2. Stratigraphic Relations of the Ipubi Formation: Siliciclastic-Evaporitic Succession of the Araripe Basin
ABSTRACT The Ipubi Formation represents the Aptian-Albian siliciclastic-evaporitic succession of Araripe Basin, NE Brazil. This succession comprises siliciclastic rocks (bituminous shales and claystones) and evaporites (gypsum and secondary anhydrite) and represents part of the lacustrine-shallow marine post-rift phase I. This study used sequence stratigraph

3. Padrões diagenéticos em arenitos de sistemas de Sabk ha costeiros-eólicos: um estudo comparativo dos reservatórios Juruá da área de Urucu, Bacia de Solimões, AM
Coastal-eolian sabkha sandstones from different ages and basins show similar diagenetic patterns, which understanding is important for their evaluation as geochemical systems and as hydrocarbon reservoirs. The Carboniferous sandstones of the Juruá Formation (Solimões Basin) are one of the most important gas reservoirs of Brazil. The sandstones and interbed

4. Estratigrafia de sequências do intervalo aptiano ao albino na Bacia do Araripe, NE do Brasil / Estratigrafia de sequências do intervalo aptiano ao albino na Bacia do Araripe, NE do Brasil
This study has as a main objective to make a detailed stratigraphic analysis of the Aptian-Albian interval in the east part of Araripe Basin, NE of Brazil which correspond, litostratigraphically, to Rio Da Batateira, Crato, Ipubi and Romualdo formations. The stratigraphic analysis was based on three different stages, the 1D, 2D and 3D analysis; these ones we

5. Time-dependent behavior of sulphatic rocks of the anhydrite and gypsum / Comportamento dependente do tempo de rochas sulfáticas de anidrita e gipso
The purpose of this thesis is to contribute for the knowledge of time-dependent behavior of sulfatic rocks of anhydrite and gypsum. Emphasis is given to provide straightforward arguments about physical mechanisms responsible for creep observed in some underground excavations in those rocks in Europe. Explanation for this phenomena is not clear yet and studie
