Oxygen isotopes in shergotty

Geochimica et Cosmochimica Acta, 1986
Abstract Oxygen isotopic fractionation among the major mineral phases of Shergotty corresponds to a temperature of last equilibration of about 1100°C. There are no large departures from equilibrium due to metamorphism, shock, or retrograde exchange.

Cenozoic Climate – Oxygen Isotope Evidence

2001
Discoveries of fossil remains of 50 million year old alligators on Ellesmere Island and 30}40 million year-old forests on Antarctica contrast sharply with our present vision of polar climates. These are not isolated discoveries or quirks of nature. An evergrowing body of faunal, Soral, and geochemical evidence shows that the Rrst half of the Cenozoic ...
