Condutividade térmica enrochas silicáticas cristalinas, com ênfase a rochas graníticas da província borborema, NE do Brasil, e sua correlação com parâmetros petrográficos e texturais

Abstract: ABSTRACT. This work focuses on rock thermal conductivity (λ) and its correlation with petrographic and textural aspects especially in granitic rocks. We demonstrate the role of these variables in order to shed some light in the behavior of conductive heat transfer in rocks. Our results demonstrate clear correlation between λ and abundance of quartz and mafic minerals. We show that there is a positive linear correlation between λ and quartz content. On the other hand, we show there a decrease on λ with mafic mi… Show more

“…In thermal analysis, once again, the main issue of this behavior seemed to be the amount of water used in the production of the composite. As discussed, there was an increase in porosity in the GR8 series composites, which directly affected, among other factors, the thermal conductivity [30][31][32]. The space left by these pores was filled with air, which made it difficult to conduct heat internally, reducing the property of the GR8 set as a whole compared to the GR6 series [29].…”

“…Essas dimensões possibilitam medir as propriedades petrofísicas em cinco pontos distintos da amostra, trazendo maior representatividade para os dados. As medidas foram feitas seguindo metodologia descrita por Figueiredo et al (2008). Visando minimizar erros de medição, foram tomados os seguintes cuidados: manutenção da temperatura ambiente em 24 a 25ºC; polimento de uma das faces do tablete, para permitir apoio total do sensor durante a análise; mesa de apoio, para estabilizar o equipamento; e pelo menos uma repetição da medida para cada ponto do tablete.…”
