Chlorine dating dating in cyprus paphos

Isotopically enriched 35Cl was added during dissolution and isotope dilution mass spectrometry (during the accelerator mass spectrometric analysis of the chlorine-36/Cl ratio) was used to determine the Cl content.Complete major element analyses and analyses of B, Gd, U, and Th were used to compute thermal neutron profiles and chlorine-36 production from radiogenic neutrons which are produced from radioactive decay within the rock. For each sample the apparent age was calculated as a function of erosion rate for rock erosion rates varying from 0 to 5 mm per thousand years.Bleach/Liquid Chlorine starts decomposing after it is manufactured.Check this link (scroll down) to see the half-life table (half-life means half of the original strength).Laboratory methods followed those described by Zedra and Phillips (2000).In brief, the samples were dissolved in a mixture of HF and HNO3 and the Cl was extracted as Ag Cl.The chlorine-36/Cl ratio was measured by accelerator mass spectrometry at PRIME Lab, . Uncertainties related to analytical factors and parameter values are probably on the order of 10%.

Note: Further down I show an easy way to measure the strength of your bleach/liquid chlorine.

The rate of chlorine-36 production by cosmic rays (thermal and fast neutrons) depends on the concentrations of potassium (K), Calcium (Ca) and chlorine (Cl), the elevation of the rock, surface orientation, and geomagnetic latitude.

The rate of accumulation of chlorine-36 depends on the balance between the production rate of chlorine-36 and on the rate of erosion of the rock surface.

Samples were collected from nine erratics over a distance of about 200 km (Table 1).

Samples were taken from upper 4 cm of the rock as fragments from hammer and chisel, from thin beds that were pried loose, or closely spaced diamond drill cores.

Six of the ages clearly fall within the age range of the Late Wisconsinan Glaciation (ca. The range in ages likely reflect events during the history of each rock that could affect its exposure to cosmic radiation such as rotation of the rock due to settlement which could have changed its orientation with the sky.
