متن کاملLake Bosumtwi Drilling Project: Shock Metamorphism in Rocks from Core
General context: Shock barometry via petrographic analysis helps to understand cratering mechanics, especially mass movements in the central uplift, including its collapse in the late stage of cratering. Shock pressures recorded in lithologies of the central uplift may exceed 45 GPa, e.g., in the Vorotilovo core drilled into the center of the Puchezh-Katunki structure [1]. In other craters, sho...
