New Data on the Sm–Nd Age of Picrites in the Lysogorsk Complex, Southern Urals

Аннотация

This paper reports new data on the age of picrites in the Lysogorsk complex, which are common in the Taratash metamorphic complex (Bashkir Meganticlinorium, the western slope of the Southern Urals). Based on Sm–Nd dating (1409 ± 89 Ma) and calculated data on the crystallization pressure and the temperature of mineral parageneses, it is concluded that picrites belong to the initial type of magmatism, which characterizes the initial stages of the Mashak magmatic event.
