“…As a special feature the DREAMS-facility has two moveable Faraday cups after the high-energy analysing magnet. They allow the simultaneous measurement of any two stable isotopes, which is important for controlling possible fractionation effects [11], and, moreover, indispensable for the application of isotope dilution AMS [12]. Hence, the detection of 35 Cl and 37 Cl, when using isotope-enriched carrier for chemistry, yield simultaneously the natural chlorine abundance in the investigated sample.…”

“…Isotope dilution (ID) is typically the preferred method for measuring the Cl concentrations because of the better precision at low concentrations compared, for example, to ion-selective electrode method or Prompt Gamma Activation Analysis (PGAA) [9][10][11][12][13]. In addition ID-AMS allows 36 Cl/Cl ratio and Cl concentration to be measured simultaneously from a single AMS target.…”

“…Samples were spiked with 4 mg of 35 Cl before dissolution. The spike method allows measurement of the total Cl concentration with high precision on the same sample material as the 36 Cl concentration (Elmore et al, 1997). Chlorine was then extracted using the method described in Stone et al (1996) Cl ratios were measured at the accelerator mass spectrometry facility of the Paul-Scherrer Institute and the ETH of Zürich, Switzerland.…”

Fluvial bedrock incision in the active mountain belt of Taiwan from in situ‐produced cosmogenic nuclides

The concentration of cosmogenic nuclides in rocks exposed at the Earth's surface is proportional to the total duration of their exposure. This is the basis for bedrock surface exposure dating and has been used to constrain valley lowering rates in the Taroko gorge, eastern Central Range, Taiwan. Taroko gorge contains a uniquely complete geomorphic record of fluvial valley lowering: continuous, fluvially sculpted surfaces are present in the lower 200 m of this marble gorge. Assuming no post-fluvial erosion of the gorge wall, the concentration of in situ-produced cosmogenic 36 Cl measured in gorge wall marbles reveals exposure ages from 0·2 ka in the active channel to 6·5 ka at 165 m above the present river. These ages imply an average fluvial incision rate of 26 ± ± ± ± ± 3 mm a − − − − −1 throughout the middle and late Holocene. Taking into account lateral gorge wall retreat after initial thalweg lowering would give rise to calculated older exposure ages. Without considering gorge wall retreat, our estimates therefore represent maximum incision rates. Estimated maximum Holocene incision rates are higher than the long-term exhumation rates derived from fission track dating. The longterm gorge development governed by tectonic uplift is superimposed by short-term variations in incision rates caused by climatic or regional tectonic changes.
