Uranium occurs in most rocks in concentrations of 2 to 4 parts per million and is as common in the Earth's crust as tin, tungsten and molybdenum.

36Cl has seen use in other areas of the geological sciences, including dating ice and live sex chat without registering.. Uranium occurs in seawater, and can be recovered from the oceans.
