What will you discover in Serra da Freita?
On one single day go back 350 millions years to see ancient continents colliding, with such power that Earth’s crust got squeezed and deformed like plasticine, melted and re-melted, faulted and thrusted until a super-continent was born.
Ancient mountains were formed and colossal amounts of magma were crystallised at depth. From then onwards these were eroded, uplifted, faulted and reworked by the natural agents, like sculptors carving blocks of rock. The fantastic landscapes and features that emerged inspired humans in the creation of myths and legends to explain processes that today geoscience shed a light on.

Compare the age of our planet to a road trip. It has been already a 4500 km long journey in which mankind only came aboard 3,6 kilometres ago.
Come with us to understand how old is our planet and imagine this age when comparing with the timescale of human existence. Learn the different Eons, Eras, Periods, Ages and Stages of the Earth’s history. In the process understand how Earth’s dating is done, through practical experiences to explain the main geological principles.

We all recognise many different types of rocks. But how can we distinguish them?
How are rocks classified? What do they mean? How were they first formed? How were they transformed throughout geological time? How can they tell us the history of our planet?
Answer all these questions while experiencing how the pioneering scientists came up with the main geological concepts.

Mountains are created by several different processes. One of them derives from the different ways magma arises from the mantle to the surface. We all know how volcanoes extrude lava to create mountains, but this is not the only process in which magma can create mountains. Often, when magma intruding the crust fails to reach the surface, creates magmatic chambers at depth. Magma then slowly solidifies and crystallizes forming batholiths and other intrusive geometries. Later these bodies are eroded and exposed at the surface forming mountains. It is possible to observe these processes at several places in Portugal.

All of us have heard about earthquakes. Many of us have heard about plate tectonics. Yet, only few of us have ever been able to recognise in the rocks direct evidence of these phenomena.
The marks left behind by earth processes are all around us in the form of faults and folds in the rocks.
Understand how to recognise and identify the plate tectonic processes behind the many faults and folds that helped create the most amazing landscapes in our planet.

Since pre-historic times mankind invoked myths and legends in an attempt to explain phenomena it couldn’t understand.
Similarly to other sciences, such as astronomy or biology, geological phenomena have been explained through the most bizarre and complex stories, fruit of the popular creative power.
Geo Logica will share with you both myths and science behind the formation of natural landscapes and forms that have kept our collective imagination intrigued during millenniums.
