Radiometric dating volcanic rock
Link: >>> http://exfindfiles.ru/dt <<< General stratigraphic relations and isotopic ages are the principal means of correlating intrusive igneous bodies. So a number of applications of the thorium-230 method are based on this chemical partition between uranium and thorium. For igneous rocks the event is usually its cooling and hardening from magma or lava. Without fail, carbon-dating confirms the biblical timescale. This is conclusive evidence that the solar system was created longer ago than the span of these half lives! This happens quite fast, yet so much helium is still in some rocks that it has not had time to escape���certainly not billions of years. Several hundred laboratories around the world are active in radiometric dating.
