The first U-Pb age data of zircons from relict spreading zones in the Middle Urals

Zones of paleospreading and crustal extension in the Urals, as well as around the world, are clearly marked sheeted dyke complexes. However, there are still no reliable isotope age data for these sheeted dyke complexes. As a rule, the age of formation of dikes was determined on the basis of age data...

Summary:Zones of paleospreading and crustal extension in the Urals, as well as around the world, are clearly marked sheeted dyke complexes. However, there are still no reliable isotope age data for these sheeted dyke complexes. As a rule, the age of formation of dikes was determined on the basis of age data of the surrounding rocks or were considered to be the same as the age of gabbro and basalts from the ophiolite sections studied.
