Which consequence results in potassium-argon dating when closed-system criteria fail?

A)Inaccurate chronological age estimation
B)Precise sample crystallization verification
C)Elevated argon diffusion gradient
D)Enhanced mineral lattice stability

💡 Explanation

Underestimation or overestimation of age estimation occurs because radioactive potassium undergoes beta decay to create argon; this process must be contained, therefore the lack of containment invalidates the radiochronological assumption, rather than altering diffusion which is a different transport phenomenon.
