The ancient rotation of the Iberian Peninsula left a magnetic trace (a.o. Science Daily)

Description

The volcanic rock found in the south of Leon (Spain) experienced a rotation of almost 60+ 300 million years ago, an example of what could have occurred across the entire Iberian Peninsula when, in that moment, it was still being formed. This fact is demonstrated by the magnetic signals of its minerals, currently being analysed by researchers. This discovery improves our understanding of a now-disappeared mountain range that stood over what is now north-western Spain, France, and the southern United Kingdom.
