During the last three years geoscientists of various institutions have developed a project aiming the setup of a geoconservation strategy in Portugal (Brilha, 2009). One of the main goals of the project was the establishment of an inventory of the most important Portuguese geosites, under the scientific point of view. In a near future, national authorities will consider this inventory as a technical support for...
O presente trabalho tem como objetivo descrever a síntese de óxido de zircônio, variando as condições de síntese com o uso de forno convencional (FC) ou forno de microondas (FM), através do método Pechini. As características estruturais dos óxidos sintetizados foram determinadas por difração de raios X, infravermelho e análises térmicas. As propriedades morfológicas foram determinadas por microscopia eletrônica...
No âmbito de um projecto mais alargado, tem vindo a ser estudada a evolução dos usos do solo partindo de informação com origem remota para uma região transmontana-duriense, com o objectivo de medir quantitativamente as mudanças em termos de usos e de acessibilidades. Assim, têm-se vindo a desenvolver um método assente em ferramentas informáticas que permita identificar e quantificar de forma automática áreas ur...
This work constitutes the first contribution for the systematisation of the geological heritage knowledge in Portugal, following the international recomendations for the characterisation of geological heritage (IUGS, ProGEO). The application of the ProGEO methodology has resulted on the creation of fourteen frameworks with international relevance, established by consensus among the Portuguese geological communi...
