Ages reported in this date list are calculated using the Libby half life of 5568 ± 30 years with 1950 as the standard year of reference; results are quoted in years b.p. and on the a.d./b.c. time scale.

The Radiocarbon Dating Laboratory of Tehran University Nuclear Centre began operation in autumn 1970. Benzene synthesis and liquid scintillation counting was chosen as the best method for processing a large number of archaeologic specimens most of whose ages are less than twice the half-life of C 14 . Advantage of benzene synthesis; ease of chemical processing light transfer properties, lack of isotopie fractionation and radioactive contamination, removal of radon, and improbability of cross-contamination, have been discussed (Noakes et al. , 1964; Noakes, Stipp, and Hood, 1964; Kowalski, 1965).
... The upper altitudes of the southern slope have a Mediterranean climate which becomes more of a desert climate on the lower slopes (Noroozi and Körner, 2018). Bovington and Masoumi (1972) and Bovington et al. (1973) determined the age of several components of soils and rocks at different points on the Alborz Mountain using 14 C dating. For example, they measured the age of carbonate concretions at 40-80 cm depth in a Calciorthid (Calcid) pedon located on Qazvin-Rasht road (15 km north of Qazvin) and determined a value of 10,380 ± 310 years before the year 1950 as a reference year. ...
