Dynamic recrystallization of quartz in veins in sandstones of metagenesis zone (Kular district, Yakutia)
Bulging recrystallization (BR) has been considered in the deformed quartz veins in the lower Triassic sandstones of the metagenesis zone in the North-Western part of the Kular district, Yakutia. BR is characterized by the formation of sutured boundaries of individuals during the crystalloplastic def...
