About me:
A technique based on cold argon and oxygen plasmas permits radiocarbon dates to be obtained on paintings that contain inorganic pigments. To listen to a podcast about this feature, please go to the Analytical Chemistry website at http: Marvin W. He applies his research to archaeological problems, specifically radiocarbon radiocarbon dating of ancient rock paintings of ancient rock paintings, the development of nondestructive radiocarbon dating of perishable artifacts, and the use of nondestructive portable X-ray fluorescence to analyze pigments in rock paintings and on ceramic decorations. Radiocarbon dates have been taken on rock paintings that have no organic pigments.

A new dating method finally is allowing archaeologists to incorporate rock paintings — some of the most mysterious and personalized remnants of ancient cultures — into the tapestry of evidence radiocarbon dating of ancient rock paintings to study life in prehistoric times. In the study, Marvin W. Rowe points out that rock paintings, or pictographs, are among the most difficult archaeological artifacts to date. They lack the high levels of organic material needed to assess a pictograph's age using radiocarbon dating, the standard archaeological technique for more than a half-century. Rowe describes a new, highly sensitive dating method, called accelerator mass spectrometry, that requires only 0. That's much less than the several grams of carbon needed with radiocarbon dating.
