Ratiometric dating

As a bonus, this can separate the excitation voltage for each channel, so that e.g.

a short circuit in one transducer won't interfere with excitation of the others.

Of course, there are many problems with such dating methods, such as parent or daughter substances entering or leaving the rock, as well as daughter product being present at the beginning.

Here I want to concentrate on another source of error, namely, processes that take place within magma chambers.

Those radimetric dating techniques have been invaluable in a recent study.

Here researchers showed that Zircons can form in the upper mantle and persist there for millions of years before entering the Earth's crust through volcanic processes.

Is it feasible to, for example, reduce the reference voltage and then use a non-inverting op-amp with 4x gain to supply the transducer excitation voltage?

Desmond Clark (1979) wrote that were it not for radiocarbon dating, "we would still be foundering in a sea of imprecisions sometime bred of inspired guesswork but more often of imaginative speculation" (Clark, 1979:7).

Writing of the European Upper Palaeolithic, Movius (1960) concluded that "time alone is the lens that can throw it into focus".

"Everything which has come down to us from heathendom is wrapped in a thick fog; it belongs to a space of time we cannot measure.

We know that it is older than Christendom, but whether by a couple of years or a couple of centuries, or even by more than a millenium, we can do no more than guess." [Rasmus Nyerup, (Danish antiquarian), 1802 (in Trigger, 19)].
