BIOGEOCHEMICAL DATA FROM WELL PRESERVED 200 KA COLLAGEN AND SKELETAL REMAINS

Jones A.M.; O'Connell T.C.; Young E.D.; Scott K.; Buckingham C.M.; Iacumin P.; Brasier M.D. (2001)

Data presented herein form part of a pilot study to reconstruct palaeoenvironment using isotopic data from 200 ka collagen and skeletal remains. To date such a study has only been possible on materials of up to 120 ka, due ...
HIGH-RESOLUTION δ18O ANALYSIS OF TOOTH ENAMEL PHOSPHATE BY ISOTOPE RATIO MONITORING GAS CHROMATOGRAPHY MASS SPECTROMETRY AND ULTRAVIOLET LASER FLUORINATION

Jones A.M.; Iacumin P.; Young E.D. (1999)

The viability of oxygen isotope analysis of tooth enamel by UV laser ablation and fluorination has been demonstrated by comparison with the Ag3PO4 extraction method. In-situ analyses by UV laser fluorination using both ...
MODERN REINDEER AND MICE: REVISED PHOSPHATE-WATER ISOTOPE EQUATIONS

Longinelli A.; Iacumin P.; Davanzo S.; Nikolaev V. (2003)

The oxygen isotope composition of bone and tooth phosphate of 34 mice specimens (Pitymus sp., Microtus arvalis and Arvicola terrestris) coming from seven different locations in Italy, Germany and Switzerland was measured ...
OXYGEN ISOTOPE ANALYSES OF CO-EXISTING CARBONATE AND PHOSPHATE IN BIOGENIC APATITE: A WAY TO MONITOR DIAGENETIC ALTERATION OF BONE PHOSPHATE?

Iacumin P.; Bocherens H.; Mariotti A.; Longinelli A. (1996)

The oxygen isotopic composition of phosphate (δ18Op) and structural carbonate (δ18Oc) of hydroxylapatite was determined in 31 bone and tooth samples of modern mammals from different countries. These two variables are highly ...
OXYGEN ISOTOPE MEASUREMENTS OF MAMMOTH AND REINDEER SKELETAL REMAINS: AN ARCHIVE OF LATE PLEISTOCENE ENVIRONMENTAL CONDITIONS IN EURASIAN ARCTIC

Genoni L.; Iacumin P.; Longinelli A.; Nikolaev V.; Gribchenko Yu. (1998)

58 samples of fossil mammoth and reindeer teeth and bones of various ages and coming from different locations were studied for the oxygen isotopic composition of their phosphate. Samples from Siberia have interstadial ...
RELATIONSHIP BETWEEN δ18O VALUES FOR SKELETAL APATITE FROM REINDEER AND FOXES AND YEARLY MEAN δ18O VALUES OF ENVIRONMENTAL WATER

Iacumin P.; Longinelli A. (2002)

The oxygen isotope composition of bone and tooth phosphate of 50 fox specimens and 30 reindeer specimens from various locations with different climatic and environmental conditions was measured. The existing relationship ...
SPATIAL AND TEMPORAL VARIATIONS IN THE 13C / 12C AND 15N / 14N RATIOS OF MAMMOTH HAIRS: PALAEODIET AND PALAEOCLIMATIC IMPLICATIONS

Iacumin P.; Davanzo S.; Nikolaev V. (2006)

Four sets of C and N stable isotope analyses carried out on mammoth hairs of different radiocarbon age from four different sites in northern Siberia are reported here. Another set of analyses from the same region, published ...
δ18O OF CARBONATE, QUARTZ AND PHOSPHATE FROM BELEMNITE GUARDS: IMPLICATIONS FOR THE ISOTOPIC RECORD OF OLD FOSSILS AND THE ISOTOPIC COMPOSITION OF ANCIENT SEAWATER

Longinelli A.; Iacumin P.; Ramigni M. (2002)

Belemnite guards of Cretaceous and Jurassic age were found to contain varying amounts of quartz deposited both on the external surface and inside the rostrum. The oxygen isotopic composition of coexisting carbonate, quartz ...
