Evolution of the san andreas fault
WebDiscrepancies in right-lateral strike-slip separation of pre-Tertiary and Tertiary geologic features along the northern San Andreas fault give rise to two contrasting views of the evolution of the fault system. One model entails two stages of right slip on the San Andreas fault, one Late Cretaceous–early Tertiary and one post-Oligocene. WebApr 5, 2024 · 1 Introduction. Field observations have shown that mature fault zone cores contain a significant proportion of clay minerals, such as the Median Tectonic Line in Japan (Jefferies et al., 2006; Wibberley & Shimamoto, 2003), the San Andreas Fault including the Punchbowl Fault in USA (French & Chester, 2024; Logan & Chester, 1987), and the …
