Radiocarbon Age of a Nevada Mummy
Science, 1965Skin tissue, bone collagen, and vegetal clothing from a well-preserved Indian mummy from a dry cave in Nevada have been analyzed radiochemically. The age is about 2500 years; the ages obtained for the various samples were in close agreement.

The Radiocarbon Method of Age Determination
American Antiquity, 1956Five years after the first publication of age measurements by the radiocarbon method (Arnold and Libby 1951) the method has been established as a powerful technique in the study of archaeology. Lists of radiocarbon dates have been published by a number of laboratories (Libby 1951, 1952, 1954, 1955; Kulp 1951, 1952; Broecker and Kulp 1956; Suess 1954 ...

Radiocarbon-calendar age relationship
Earth and Planetary Science Letters, 1971Abstract Radiocarbon dated tree-rings from eight laboratories were analyzed by multiple regression and 250 yr means to determine the relationship between radiocarbon dates reduced to a common base and tree-ring (calendar) dates for the last 7100 yr.

Radiocarbon ages of humic substances in chernozems
Eurasian Soil Science, 2008Data on radiocarbon ages of different fractions of humus (humic acids, fulvic acids, and humin) in the profiles of chernozems are analyzed. A chronoecological grouping of humus in modern and buried (fossil) soils is suggested. An increase in the radiocarbon age of humic substances down the soil profile has a stepwise character. It is shown that the 14C

Radiocarbon Age-Determinations From Lignotubers
Australian Journal of Botany, 1988Large plate-like lignotubers formed by Eucalyptus botryoides Sm. were examined at a site on the south coast of New South Wales. Circumstantial evidence suggests that they are of great antiquity, yet 14C activity measurements of samples taken from lignotubers or associated stump wood corresponded to young ages, and it is clear that low durability of ...

Radiocarbon Age of the Damariscotta Shell Heaps
American Antiquity, 1957The large oyster shell heaps on both sides of the Damariscotta River, just north of the towns of Damariscotta and Newcastle, Maine, have been known for many years and both geologists and archaeologists have speculated about their age. During the summer of 1955 I made 2 collections of Mya shells from the largest shell heap on the west side of the river (

Radiocarbon, 2017
AbstractA radiocarbon (14C) dating technique with accelerator mass spectrometry (AMS) was applied to estimate the year of death and the year of birth of unidentified human remains. Because many of the samples have been preserved in formaldehyde, it was necessary to evaluate the influence of formaldehyde on carbon ages.

Age determination by the radiocarbon method
1999Radioaktivni izotop ugljika, 14C, nastaje u atmosferi međudjelovanjem neutrona iz kozmičkog zračenja i jezgara 14N. Nastali 14C atomi se oksidiraju u 14CO2, koji se s oksidima drugih ugljikovih izotopa jednoliko raspodjeljuje po cijeloj atmosferi, hidrosferi i biosferi, te tako ulazi u životni ciklus biljaka, životinja i ljudi.

Radiocarbon Dates and the Scottish Iron Age
Antiquity, 1969Within the past two years the chronology of the later prehistoric period in Scotland has been given a new precision by no less than 24 C14 dates obtained from nine different sites, most of which are conventionally assigned to the pre- Roman Iron Age. Previously the identification and dating of the cultures and sites of this period had depended almost ...
