16^th IAGOD Quadrennial Symposium 2026

Visit to Argemela and Panasqueira mine

Date: 3^rd to 5^th September

Panasqueira mine is the main wolframite mining operation in Europe and one of the most significant in the world, exploring a hydrothermal deposit of the quartz vein type with W(-Sn-Cu). Exploration is underground and the mine continues to play a very important role in the global supply of high-quality wolframite concentrates together with cassiterite and chalcopyrite concentrates as by-products. In addition to its economic importance, the Panasqueira Mine constitutes a geological treasure, providing magnificent and valuable mineral specimens and allowing the analysis of metallogenic processes related to Variscan peraluminous granites. The Argemela intrusion consists of a rare metal granite (RMG) body associated with tin mineralization and minor wolframite veins. The Panasqueira and Argemela mines offer valuable insights into the Variscan processes and mineral formation that will be discussed in this fieldtrip.

Iberian pyrite belt: Neves Corvo and Aljustrel

Date: 3^rd to 6^th September

Iberian Pyrite Belt, probably the largest VMS district on Earth: geology, stratigraphy, metallogeny, a bit of past and a lot of future. This field trip provides an excellent opportunity to visit the Neves-Corvo and Aljustrel deposits, both essential for EU CRM/SRM and Energy Transition agendas. Participants will acquire a comprehensive understanding of IPB stratigraphy, ore geology, exploration vectors, mining social perception and sustainability, and mine site reclamation (Lousal, Aljustrel). Key volcano-sedimentary and mineralized sequences will be observed at the LNEG drill core shed and in selected outcrops.

Estremoz marbles and regional geology

Date: 3^rd to 5^th September

During this field trip we will have the opportunity of going through a deep dive in the regional geological history of the Estremoz anticline with opportunities to see detailed regional stratigraphy and deformation features. This area is known for its marble production, a raw material with big impact in the region’s economy, culture, and history. We will visit examples of marble quarries and show case one of the oldest and most productive surfaces of Portugal's marble extraction.

Maximum number of registrations: 18

Geology and the volcanic landscapes of the Azorean islands

Join us for a lifetime opportunity to discover some of the most well-kept secrets of Portuguese’s Geology in the Azores islands. We are offering an extended and a shorter version of this field trip that involves a visit to the unique volcanic landscapes of the different islands and access to some cultural aspects of the region.
