title:
Ionium–thorium dating
text:
Ionium-thorium dating is a technique for determining the age of marine sediments based upon the quantities present of nearly stable thorium-232 and more radioactive thorium-230. Uranium is soluble in water. However, when it decays into thorium, the latter element is insoluble and so precipitates out to become part of the sediment. Thorium-232 has a half-life of 14.5 billion years, but thorium-230 has a half-life of only 75,200 years, so the ratio is useful for dating sediments up to 400,000 year
