COMPARISON OF TERRESTRIAL AND MARINE RECORDS OF CHANGING CLIMATE OF THE LAST 500,000 YEARS

Tzedakis P.C.; Andrieu V.; de Beaulieu J.L.; Crowhurst S.; Follieri M.; Hooghiemstra H.; Magri D.; Reille M.; Sadori L.; Shackleton N.J.; Wijmstra T.A. (1997)

A broad correspondence between long pollen sequences and the deep-sea oxygen isotope record has been noted for some time, but there has been little effort to explore just how similar the two types of evidence are in terms ...
ORIGIN OF MAGNETITE IN OXIDIZED CV CHONDRITES: IN SITU MEASUREMENT OF OXYGEN ISOTOPE COMPOSITIONS OF ALLENDE MAGNETITE AND OLIVINE

Choi B.G.; McKeegan K.D.; Leshin L.A.; Wasson J.T. (1997)

Magnetite in the oxidized CV chondrite Allende mainly occurs as spherical nodules in porphyritic-olivine (PO) chondrules, where it is associated with Ni-rich metal and/or sulfides. To help constrain the origin of the ...
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 ...
