Thorium - Wikipedia


Uranium–thorium dating is commonly used to determine the age of calcium carbonate materials such as speleothem or coral, because uranium is more soluble in water than thorium and protactinium, which are selectively precipitated into ocean-floor sediments, where their ratios are measured. The scheme has a range of several hundred thousand years.

Locations of Deposits - Massachusetts Institute of Technology


Other deposits include hematite-breccia complex deposits, magmatic-hydrothermal uranium in iron-oxide Cu-Au deposits and quartz-pebble conglomerate deposits (World Nuclear, 2010). Thorium is mined in conjunction with uranium, so much that estimates of reserves for these elements are made based off of uranium content.
