The presence of Archean granite forming the core of an updomed and overturned sequence of strata at Vredefort, South Africa, has been known for over 70 years. Recent geophysical, geochemical, and geological evidence has given rise to the proposal that the basement granite core has also been overturned, presenting a section of the earth's granitic crust to view and that radial traverses in the Vredefort basement penetrate through a ∼15 km thick section of the Archean crust, when moving from the… CONTINUE READING
