Definition

Amino acid racemization. The phenomenon of conversion of “left-handed” (l or “levo”) amino acids to their “right-handed” (d or “dextro”) form. In most living systems, 100 % of the amino acids are of the L form, and the conversion results in an equal mixture of d and l when the racemization reaction is complete.

Marine Sediment. Material that accumulates in the marine environment. This article focuses on material collected in cores from deep-sea settings.

Among the wide range of applications of amino acid geochronology, this technique is especially well suited for dating deep-sea sediments using foraminifera. Foraminifera inhabit most of the World Ocean and they contain relatively high concentrations of amino acids that are well retained by their carbonate test. The stable thermal environment of deep-sea sites minimizes the often-complicating effect of variable temperature on the long-term rate of racemization. Some of the earliest research on amino acid geochronology took...
