Can carbon dating be used for lava flows

Radiocarbon dating can really only be used in applications of dating organic compounds, which is why it's so good in things like archaeology. It's interesting that isochrons depend on chemical fractionation for their validity. At equilibrium, which should be attained inyears for this decay series, we should expect to have 3 million times as much U as radium to equalize the amount of daughter produced. After perhaps 10 or 20 times the half-life, the remaining amount of carbon will be insignificant, and can't be accurately measured. Thus we need to have an uneven distribution of D relative to N at the start.

Can carbon 14 be used for dating lava flows

This radium cannot be the result of decay of uranium, since there is far too much of it. This is not necessarily a problem for radiometric dating, because it can be taken into account. These substances will then fall to the lower portion of the magma chamber, where it is hotter, and remelt. Perhaps magma that is uranium rich tends to be lighter than other magma. Helens, Vulcanello, and Lipari and other volcanic sites. This can happen, for example, if the earlier formed minerals are heavier than the liquid portion and settle to the bottom of the magma chamber as shown in Figure 3.
