Cesium dating

Developed in the 1950s, it was important in developing the theory of plate tectonics and in calibrating the geologic time scale.

In the three Connecticut, USA, lakes studied, sediment accumulation rates changed abruptly to higher values between 40-50 yrs ago (increasing by factors of 2.2, 2.9, and 3.0).

Lava flows that lie above and below rock beds with ancient human fossils are a good—and true—example.

The mineral sanidine, the high-temperature form of potassium feldspar, is the most desirable.

The depth of sharp peaks in concentrations of trace metals also matched.

In general, this evidence supports the idea that sediments in these lakes have simply been buried, without significant diagenetic remobilization of Pb and trace metals .
