GEOPHYSICAL EXPLORATION IN ARGEMELA DISTRICT, FUNDAO, PORTUGAL - VLF RESULTS

(STEF92 Technology, 2024-11-15, Ricardo Ribeiro, Rui Moura, Ana Rita Carvalho, Alexandre Lima, Charles Gumiaux)

Raw materials are essential for Europe-s industrial base, as they are used to produce vital goods and technologies. The European Comission-s assessment identifies lithium and tin as critical and strategic raw materials due to rising demand. A PhD thesis aims to create a 3D geological model of the Argemela District in Central Portugal to provide vital information about the genesis of the hydrothermal tin and lithium mineralizations founded in the region. The study places emphasis on the very-low-frequency (VLF) ele...

PRELIMINARY RESULTS OF ELECTRICAL RESISTIVITY FOR SUBSOIL ENVIRONMENTAL ASSESSMENT OF THE ALIJO LITHIUM RICH PEGMATITE QUARRY, BARROSO, PORTUGAL

(STEF92 Technology, 2022-11-15, Maria Cristina Marques, Rui Moura, Alexandre Lima, Carla Patinha)

In recent years, with the rise of a growing economic and technological interest in lithium mineral resources, there has been a parallel concern, on the part of some local populations and even national environmental groups, for a hypothetical contamination problem that this type of exploitations may cause on the quality of groundwater. Thus, the present study was based on an evaluation of an open-pit quarry, in the socalled Alijo quarry, located in the North of Portugal, in the parish of Canedo, Ribeira de Pena mun...

GEOPHYSICS IN GOLD EXPLORATION: SOME APPLICATIONS TO NORTHERN PORTUGAL GOLD DEPOSITS

(STEF92 Technology, 2017-06-20, Sara Leal, Rui Moura, Alexandre Lima, Aleksandr Pivtorak, Diogo Rodrigues)

Show more

The geophysical surveys methods have not been extensively used in gold exploration in Northern Portugal. This is based on the fact that most mineralized zones contain low and erratic sulphide contents. In this work were tested three different types of geophysical surveys combined with geochemical surveys, in order to define anomalies that are closely correlated with the locations of known mineralized zones. The aim of the work is to study some gold deposits in Northern Portugal (Lagoa Negra and Castromil) with the...
