This article is about the lunar hotspot. For the Cornell Branch of the Telluride Association also known as "CBTA", see Telluride House.
The Compton–Belkovich Thorium Anomaly is a volcanic complex on the far side of the Moon.[1] It was found by a gamma-ray spectrometer in 1998 and is an area of concentrated thorium, a 'fertile' element.[1][2] 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.[3]
