2012GC004616_Sorlien_etal_Supplemental_FiguresMarch52013.docxWord 2007 document1637KMultibeam bathymetry, topography, faults, and wells. Bathymetric data from Dartnell and Gardner [1999]. Onshore faults from the Southern California Community Fault Model [Plesch et al., 2007], except the Newport-Inglewood fault from Wright [1991]. Wells incorporated into this study shown by numbered circles: (1) 3490-1 (west of figure), (2) Humble H-9R-6, (3) Shell Santa Monica CH-1, (4) Humble H9R-5, (5) Humble H-9R-7, (6) Mobil SM-1, (7) Signal II-1, (8) Standard CH 9R-1, (9) Humble H9R-2, (10) Humble H-9R-4, (11) Humble H10-R7, (12) Shell 293-1, (13) Texaco 295-3, (14) Mobil SP20, (15) Standard 296-1, (16) Humble-H10R-1, (17) Mobil 304-1, (18) Sohio 302-2, (19) Challenger Minerals 311-1. PdR = Playa del Rey, RK = Redondo Knoll, PVH = Palos Verdes Hills, SPS=San Pedro Shelf, LK=Lasuen Knoll.
2012GC004616appendixFigure1.jpgJPEG image440KClose-up of 16 m grid of seafloor bathymetry on the Shelf Projection and northwest San Pedro Escarpment; data from Dartnell and Gardner [1999]. Labeled areas of outcrop are middle and late Miocene Monterey Formation dated from seafloor samples in Nardin and Henyey [1978]. Labeled anticlines on the basin floor (west) are associated with the right-lateral San Pedro Basin fault (not shown). Gray curves are crests of anticlines mapped from seismic profiles (solid where unambiguously correlated, dashed where less certain). The trends of the anticlines are more east-west than the trend of the Palos Verdes anticlinorium. Wells 7 through 10 are located. Information about these wells is in the Supplementary Appendix 1. Cross section A-A″ (Figure 3A), G-G' (Figure S2), and H-H' (Figure 6) are located.
2012GC004616BasementUTM11NAD83LineTraceXYT.txtplain text document243KU.S. Geological Survey seismic reflection profile G-G' across part of the southwest limb of the Palos Verdes anticlinorium, with corresponding 1:1 depth section; located on Figures 1a, 1d, and S1. The San Pedro Basin fault is right-lateral and offsets the Santa Monica Bay fault. The normal separation exhibited by the shallow part of the Santa Monica Bay blind fault is related to a releasing double bend of the San Pedro Basin fault southeast of this profile. Data from Sliter et al. [2005].
2012GC004616BaseRepettoUTM11NAD83LineTraceXYT.txtplain text document399KMigrated multichannel seismic reflection profile provided by Western Geophysical, located in Figures 1a and 1d. Progressive tilting of the Pliocene section is consistent with displacement gradient models for broad forelimbs [Wickham, 1995]. The reflection character of the post-Repetto basin sediments is consistent with the rapidly deposited turbidites [e.g., Normark et al., 2006]. The inset images progressively steeper unconformities with depth within the turbidites (paired yellow arrows). The interval above the youngest unconformity is correlated to ODP site 1015 and so is younger than ~50 ka. An example of 2 mm/yr depositional rate would mean that the entire fill (above the deepest paired yellow arrows) would postdate 200 ka and ongoing tilting would be subtle. This fill is not present in the hanging wall of the northeastern (yellow) strand of the San Pedro Escarpment faults, so there is no simple way to detect ongoing tilting there.
2012GC004616HuenemeUnconformityUTM11NAD83LineTraceXYT.txtplain text document609KDepth-converted migrated Western Geophysical profile M-M', located on Figures 1a and 1d. Displayed with no vertical exaggeration, the anticlinorium is broad and gentle. The thickest interval between Catalina Schist and base Repetto is along the crest of the anticline above the Palos Verdes fault; this is an inverted basin. San Pedro Basin fault is just beyond left edge; Palos Verdes fault is labeled as PVF. The labeled “Repettian,” “Delmontian,” and “Mohnian” are outcrop of Pliocene to middle Miocene benthic foraminiferal stages as sampled in this area by Nardin and Henyey [1978] (Figure 1a).
