“…Many of these species, from the Island of Car Nicobar, were originally described by Schwager (1867). Miocene to Oligocene faunal assemblages of the Japan Trench sites are also similar to those from the northeast Pacific coast described by White (1956), Pierce (1956), Kleinpell (1938), Mallory (1959), and Sullivan 'N 40°37.79'N 40°37.80'N 40°37.61'N 39°44.13'N 39°44.13'N 39°44.13'N 39°45.05'N 39°45.05'N 39°45.08 1962); to those from the Central Pacific described by Douglas (1973); and to those from the Japan region described by Asano (1953aAsano ( , 1953bAsano ( , 1958. A large number of late Miocene to Pliocene species of the Japan Trench sites appear to be cosmopolitan and have recently been discussed, with respect to paleobathymetry from the Mediterranean El Cuervo section of Andalusia, Spain, by Berggren et al (1976).…”

Deep sea drilling in the Japan Trench area recovered a Late Cretaceous to Pleistocene sedimentary and biostratigraphic record unraveling the tectonic and paleobathymetric history of the convergent margin. Benthic foraminiferal assemblages spanning the Late Cretaceous to the late Pleistocene permit reconstruction of the paleobathymetric history of this area. During the Late Cretaceous a deep bathyal environment persisted, characterized by deposition of finegrained turbidites. Sometime during the early Paleogene, uplift occurred, followed by erosion and deposition of a conglomerate which presumably derived from a nearby volcanic source. A shallow marine sequence consisting of a massive sandstone marked by shallow-water benthic foraminifers, gastropods, and pelecypods was deposited in the late Oligocene. During the early Miocene a fine-grained turbidite-claystone was deposited on a subsiding slope which reached upper middle bathyal depth. Subsidence continued throughout the Miocene and reached lower bathyal depths (2000 m + ) by the late Miocene, accompanied by deposition of a thick hemipelagic sequence. The same depositional environment persisted through the early Pliocene. A gradual shoaling from 2000 meters + to 1500 meters (present depth) is indicated by benthic foraminiferal assemblages of the late Pliocene to Pleistocene.

Insights from low-temperature thermochronometry into transpressional deformation and crustal exhumation along the San Andreas fault in the western Transverse Ranges, California

The San Emigdio Mountains are an example of an archetypical, transpressional structural system, bounded to the south by the San Andreas strike‐slip fault, and to the north by the active Wheeler Ridge thrust. Apatite (U‐Th)/He and apatite and zircon fission track ages were obtained along transects across the range and from wells in and to the north of the range. Apatite (U‐Th)/He ages are 4–6 Ma adjacent to the San Andreas fault, and both (U‐Th)/He and fission track ages grow older with distance to the north from the San Andreas. The young ages north of the San Andreas fault contrast with early Miocene (U‐Th)/He ages from Mount Pinos on the south side of the fault. Restoration of sample paleodepths in the San Emigdio Mountains using a regional unconformity at the base of the Eocene Tejon Formation indicates that the San Emigdio Mountains represent a crustal fragment that has been exhumed more than 5 km along the San Andreas fault since late Miocene time. Marked differences in the timing and rate of exhumation between the northern and southern sides of the San Andreas fault are difficult to reconcile with existing structural models of the western Transverse Ranges as a thin‐skinned thrust system. Instead, these results suggest that rheologic heterogeneities may play a role in localizing deformation along the Big Bend of the San Andreas fault as the San Emigdio Mountains are compressed between the crystalline basement of Mount Pinos and oceanic crust that underlies the southern San Joaquin Valley.

The marine foraminiferal stages assigned to the middle Tertiary system were proposed and defined by Kleinpell (1938), and those assigned to the lower Tertiary were proposed and defined by Mallory (1959). Correlation of the middle Tertiary stages with corresponding mammalian "ages" is adopted from Turner (1970, fig.…”

The upper Mesozoic and Cenozoic sedimentary series within about 20 miles on either side of the San Andreas fault has been mapped and systematically classified. Southwest of the fault, the sedimentary series overlies a Mesozoic crystalline basement of plutonic and metamorphic rocks, is from 5,000 to 40,000 feet thick, and is divided into four lithologic sequences. Northeast of the fault, the sedimentary series overlies a Mesozoic basement of eugeosynclinal rocks (Franciscan rocks and serpentine), is from 25,000 to 40,000 feet thick, and is divided into five lithologic sequences. These sequences are in large part separated by regional unconformities. The Cretaceous and Tertiary sequences are marine and terrestrial southwest of the fault, marine northeast of it. The youngest sequence, mainly of Quaternary age, is composed of lithologically similar valley sediments on each side of the fault. Most of the sedimentary sequences are divided into lithologically distinct formations of large areal extent, some of which in turn are divided into local members. A standardized set of names has been designated for the formations and members for this region, using the existing names that are applicable. On opposite sides of the San Andreas fault, not only are the basement rocks contrasting, but the oldest corresponding sedimentary sequences are dissimilar; the successively younger sequences are progressively less different. This condition appears to be the result of persistent right-lateral movement on the fault since Cretaceous time.
