The latter are of particular concern, especially in estuarine environments. Some of the problems associated with K-Ar dating are Excess argon.

Radiocarbon Dating and Calibration, in I. Shennan, A. Horton Eds. Marine Science Faculty Publications. Minerals should not contain any excess Ar because Ar should not enter the crystal structure of a mineral when it crystallizes.

Thus, it always better to date minerals that have high K contents, such as sanidine or biotite. Radiocarbon Dating and Calibration. Elsevier - Digital Commons. Advanced Search.
