Thorium - World Nuclear Association

The most common source of thorium is the rare earth phosphate mineral, monazite, which contains up to about 12% thorium phosphate, but 6-7% on average. Monazite is found in igneous and other rocks but the richest concentrations are in placer deposits, concentrated by wave and current action with other heavy minerals.

Occurrence of thorium - Wikipedia

Present knowledge of the distribution of thorium resources is poor because of the relatively low-key exploration efforts arising out of insignificant demand. There are two sets of estimates that define world thorium reserves, one set by the United States Geological Survey (USGS) and the other supported by reports from the OECD and the International Atomic Energy Agency (the IAEA).
