“…The radiocarbon ages are inverted in several boreholes, which we attribute to reworking of older sediments. Studies of deltaic sequences elsewhere have shown that the youngest age, 4.3 ka in the case Downloaded by [University of North Dakota] at 05:03 20 December 2014 of the younger alluvium in the Santa Maria River valley, best indicates the time of burial by fluvio-deltaic facies (Stanley and Hait, 2000). This inference is confirmed by the 3.5 ka age 0.75 m above the upper alluvium/dune sheet contact.…”

“…We attribute the age inversions to reworking of older materials in the fluvio-deltaic system of the Santa Maria River, a common feature in such settings elsewhere (Stanley and Hait, 2000). Based on these anomalies, Stanley and Hait (2000) recommend using the youngest radiocarbon age as an indicator of burial age of the underlying deposit, which for our data set is 4360 ± 70 yr B.P.…”

Late Quaternary deposition in many terrestrial basins along the California coast consists of interbedded fluvial, estuarine, and dune facies deposited in response to relative sea level changes. Radiocarbon dating of sediments retrieved from boreholes drilled through the Guadalupe dune sheet at the mouth of the Santa Maria River, where uplift rates are zero or less, indicate that estuarine deposition began locally around 9-11 ka in response to rising sea level. The estuarine deposits were then buried by dune sands around 3.5-4.3 ka, perhaps in response to sea-level regression during mid-Holocene (~4.5 ka) glaciation and not the earlier glacial periods, as previously inferred by others.

“…However, we can manage this difficulty by analysing colluvial wedges and regarding the derived rates as minimum values. Radiocarbon dating of dispersed carbon and charcoal in delta environments often leads to increments as large as several thousand years in the apparent ages of deposition (Stanley and Hait, 2000). However, if the age determinations in this paper are reliable, we can draw three main conclusions.…”

Palaeoseismological and archaeological analysis of a trench enabled us to estimate the Holocene slip rates on the East Helike Fault, flanking the south-western Gulf of Corinth. We recognized two major fault strands within the trench: the 'north fault' controls a succession of three colluvial wedges and the deposition of a 2.7 m thick sedimentary sequence. The 'south fault' controls the deposition of a 2.9-m thick brownishred colluvium. Based on colluvial stratigraphy, radiocarbon dating of the sediments suggests that the slip rate was c. 0.3 mm yr )1 from 10 250 to c. 1400 BP, when it increased dramatically to c. 2.0 mm yr )1 after a strong earthquake event near 1400 BP. The faster slip rate evidently increased the sedimentation rate.

“…Obtaining age control from fluvial deposits, however, has been difficult due to limited organic material for radiocarbon dating and problems with reworking of old carbon in many fluvial sediments (e.g. Blong & Gillespie 1978; Gillespie et al 1992; Stanley & Hait 2000). Other techniques, such as cosmogenic nuclide dating of terrace surfaces and U‐series dating of pedogenic carbonate, provide minimum ages on sediment deposition and landform abandonment (e.g.…”

Luminescence dating of fluvial deposits: applications to geomorphic, palaeoseismic and archaeological research

Fluvial deposits and landforms are important archives of river response to climate, tectonics and base level change and are commonly associated with archaeological sites. Unlike radiocarbon dating, the target material for optically stimulated luminescence (OSL) dating (sands and silts) is nearly ubiquitous in fluvial deposits and the age range for OSL spans the last glacial-interglacial cycle, a time period of interest to many Quaternary scientists. Recent advances in OSL techniques and the development of single-grain dating capabilities have now allowed fluvial deposits, and other deposits commonly afflicted with incomplete zeroing of the luminescence signal, to be dated. The application of OSL dating to fluvial deposits is discussed with respect to its potential to provide important contributions to research in the fields of geomorphology, palaeoseismology and archaeology. Examples are given from each research field.
