Resumo: | In this paper we present the methodological procedures involved in the digital imaging in mesoscale of a block of travertines rock of quaternary age, originating from the city of Acquasanta, located in the Apennines, Italy. This rocky block, called T-Block, was stored in the courtyard of the Laboratório Experimental Petróleo "Kelsen Valente" (LabPetro), of Universidade Estadual de Campinas (UNICAMP), so that from it were performed Scientific studies, mainly for research groups universities and research centers working in brazilian areas of reservoir characterization and 3D digital imaging. The purpose of this work is the development of a Model Solid Digital, from the use of non-invasive techniques of digital 3D imaging of internal and external surfaces of the T-Block. For the imaging of the external surfaces technology has been used LIDAR (Light Detection and Range) and the imaging surface Interior was done using Ground Penetrating Radar (GPR), moreover, profiles were obtained with a Gamma Ray Gamae-spectômetro laptop. The goal of 3D digital imaging involved the identification and parameterization of surface geological and sedimentary facies that could represent heterogeneities depositional mesoscale, based on study of a block rocky with dimensions of approximately 1.60 m x 1.60 m x 2.70 m. The data acquired by means of terrestrial laser scanner made available georeferenced spatial information of the surface of the block (X, Y, Z), and varying the intensity values of the return laser beam and high resolution RGB data (3 mm x 3 mm), total points acquired 28,505,106. This information was used as an aid in the interpretation of radargrams and are ready to be displayed in rooms virtual reality. With the GPR was obtained 15 profiles of 2.3 m and 2 3D grids, each with 24 sections horizontal of 1.3 and 14 m vertical sections of 2.3 m, both the Antenna 900 MHz to about 2600 MHz antenna. Finally, the use of GPR associated with Laser Scanner enabled the identification and 3D mapping of 3 different radarfácies which were correlated with three sedimentary facies as had been defined at the outset. The 6 profiles showed gamma a low amplitude variation in the values of radioactivity. This is likely due to the fact of the sedimentary layers profiled have the same mineralogical composition, being composed by carbonate sediments, with no clay in siliciclastic pellitic layers or other mineral carrier elements radioactive |

Esse bloco rochoso, denominado de T-Block, foi armazenado no pátio do Laboratório Experimental de Petróleo "Kelsen Valente" (LabPetro), da Universidade Estadual de Campinas (UNICAMP) para que a partir dele fossem realizados estudos científicos, principalmente para grupos de pesquisa das universidades e centros de pesquisa brasileiros que atuam nas áreas de caracterização de reservatório e imageamento digital 3D. A proposta deste trabalho consiste na elaboração de um Modelo de Sólido Digital, a partir da utilização de técnicas não-invasivas de imageamento digital 3D das superfícies interna e externa do T-Block. Para o imageamento das superfícies externas foi utilizada a tecnologia LIDAR (Light Detection and Range) e para o imageamento das superfícies internas foi feita a utilização do Ground Penetrating Radar (GPR), além disso, foram adquiridos perfis de Gamma Ray com um Gamaespectômetro portátil. O objetivo do imageamento digital 3D consistiu na identificação e parametrização de superfícies geológicas e de fácies sedimentares que pudessem representar heterogeneidades deposicionais em mesoescala, tomando como base de estudo um bloco rochoso com dimensões de aproximadamente 1,60m x 1,60m x 2,70 m. Os dados adquiridos por meio do Laser Scanner terrestre disponibilizaram informações espaciais georreferenciadas da superfície do bloco (X, Y, Z), além de valores de variação de intensidade de retorno do raio laser e dados RGB com alta resolução (3 mm x 3 mm), totalizando 28.505.106 pontos adquiridos. Essas informações foram utilizadas como auxilio durante a interpretação dos radargramas e estão prontas para ser exibidas em salas de realidade virtual. Com o GPR, foram adquiridos 15 perfis de 2,3 m e 2 grids 3D, cada um com 24 seções horizontais de 1,3 m e 14 seções verticais de 2,3 m, tanto com a antena de 900 MHz quanto com a antena de 2600 MHz. Por fim, o uso do GPR associado ao Laser Scanner possibilitou a identificação e mapeamento 3D de 3 radarfácies distintas as quais foram correlacionadas a 3 fácies sedimentares já que já haviam sido definidas no inicio do trabalho. Os 6 perfis de raios gama mostraram uma baixa variação na amplitude dos valores de radioatividade. Provavelmente, isso ocorreu devido ao fato das camadas sedimentares perfiladas possuírem a mesma composição mineralógica, sendo compostas por sedimentos carbonáticos, com ausência de argila siliciclástica nas camadas mais pelíticas ou de outro mineral portador de elementos radioativosapplication/pdfporUniversidade Federal do Rio Grande do NortePrograma de Pós-Graduação em Geodinâmica e GeofísicaUFRNBRGeodinâmica; GeofísicaModelo de sólido digital (Digital solid model).
