UCLA radiocarbon dates IV.

Abstract

Reports of carbon-14 dating are grouped under archeologic-historical dates and under geophysical, geologic, and biologic measurements. Samples studied in the first group came from the United States, Mexico, South America, the Pacific, Europe, Asia, and Africa. The second group included studies of carbon-14 in the atmosphere in California and Galapagos Islands, bomb radiocarbon in human tissues; plants and seaweed from California; seawater off Baja California, Mexico; tree rings from Arizona and California; vegetation and climate, southwestern United States; geologic processes as shown in samples from California and Wisconsin.
