Abstract

The highest point of orogeny in the Santa Lucia range occurs 50-60km from the nearest active faulting. This orogeny is believed to have occurred hear due to relatively weak Franciscan Mélange versus the granitic material at the fault boundary. This paper studies the development of a knickpoint in San Simeon creek to identify the role of relatively recent (graded time) tectonic activity in orogeny of the Santa Lucia range.
The 2003 earth quake is evidence of recent base level change with the occurrence of orogeny supporting the theory of continuous orogeny in recent and graded time scale. Although the knickpoint occurs in a resistant portion of the Franciscan Mélange, overall it is a relatively soft substrate suggests that Garcia and Mahan’s theory of Quaternary orogeny.
