The Compton–Belkovich Thorium Anomaly is a hotspot (volcanic complex) on the Moon. It is on the far side of the Moon and was found by a gamma-ray spectrometer in 1998. It is an area of concentrated thorium, a 'fertile' element. Lunar rock samples from the Apollo missions reveal that most lunar volcanism occurred around 3 to 4 billion years ago, but this feature could have formed as recently as 1 billion years ago due to the unknown history of the moon's far side.
