Spain's First Meteorite Crater Discovered in Almeria 2026

Spain's first meteorite impact crater has been confirmed in the Tabernas basin of Almeria, a discovery that marks a milestone in Spanish geology. The finding, led by researcher Juan Antonio Sánchez Garrido and his colleague Sebastián Sánchez, began as a study of the Gordo Megabed formation and ended with international scientific recognition.

The pair was examining a well-known set of rocks in the Tabernas desert, an area already studied for its seismic activity. But something didn't add up. Chemical and magnetic anomalies pointed to an event far more violent than an earthquake.

How the Almeria Meteorite Crater Was Discovered

Sánchez Garrido and Sánchez were not looking for a meteorite. They were investigating the geological history of the Gordo Megabed, a formation in the Tabernas basin. The region is famous for its arid badlands and has long been a natural laboratory for geologists.

As they analyzed the rocks, they noticed a geochemical anomaly: certain elements were present in concentrations that did not match normal sedimentary or seismic processes. The magnetic properties of the rocks also stood out. Together, these clues suggested that around 8 million years ago, something caused an immense spike in temperature and pressure.

The only phenomena capable of producing such effects are a nuclear explosion or a meteorite impact. Given the timeframe, a nuclear event was impossible. That left a meteorite—a first for Spain.

Why the Tabernas Basin Holds the Evidence

The Tabernas basin is part of the Betic Cordillera, a mountain range that formed as the African and Iberian plates collided. Its sedimentary layers preserve a record of millions of years of Earth history. The Gordo Megabed itself is a distinctive layer of rock that has attracted scientific attention for decades.

According to Sánchez Garrido, the initial resistance from some quarters was significant. The idea of a meteorite impact in Spain was novel, and extraordinary claims require extraordinary evidence. The team gradually built a case by adding specialists in geochemistry, magnetism, and impact geology.

Their persistence paid off. The international scientific community has now confirmed that the structure is indeed an impact crater, the first ever identified in Spain.

What Makes This Crater Scientifically Important

Impact craters are relatively rare on Earth's surface because tectonic activity and erosion erase them over time. Finding one in Spain fills a gap in the European impact record. It also provides a new site for studying the effects of hypervelocity impacts on sedimentary rocks.

The Almeria crater is not just a local curiosity. It helps scientists understand the frequency and consequences of meteorite strikes in the region. Moreover, it offers a window into the geological conditions of the late Miocene, when the impact occurred.

Sánchez Garrido is convinced that more craters may be waiting to be found. "I am sure there could be another," he said, suggesting that Spain's geological record may hold further impact structures.

Key Takeaways from the Discovery

• The first meteorite impact crater in Spain has been confirmed in the Tabernas basin, Almeria.
• The discovery was made by Juan Antonio Sánchez Garrido and Sebastián Sánchez while studying the Gordo Megabed.
• Evidence includes geochemical anomalies and magnetic signatures indicating extreme temperature and pressure about 8 million years ago.
• The international scientific community has validated the finding.
• The researchers believe additional craters may exist in Spain.

Comparison with Other Impact Craters

Spain's new crater joins a global list of confirmed impact structures. The table below shows how it compares with some well-known craters in Europe and beyond.

What Happens Next for the Almeria Crater

Research is ongoing. Sánchez Garrido and his team want to learn everything possible about the impact: its size, the angle of approach, and the environmental effects at the time. Such details can be gleaned from shocked minerals, melt breccias, and ejecta layers. The background to this story is set out in Hickman Crater: How Google Earth Revealed a 260-Meter Meteorite Impact.

The discovery also raises the possibility of other craters in Spain. The Iberian Peninsula has a variety of geological settings, some of which could preserve impact signatures.
