Analysis of the properties of soils developed in marine terrace deposits that are displaced by the San Simeon fault zone in central California allows for their correlation across the fault. Based on a suite of 7 soil and stratigraphic parameters determined from 17 soil profiles, the second, third, and fourth marine terraces west of the fault correlate best with the first, second, and third terraces east of it. Limited radiometric age control suggests that the first terrace west of the fault probably correlates to oxygen isotope Stage 3 at about 60 ka, whereas the second through forth terraces correlate to late and early Stage 5 and Stage 7 at about 80 to 105,120, and 200 to 230 ka, respectively.
