title: Elements 112 to 119: were they present in meteorites?
abstract: Chondrites contain a small fission xenon component of unexplained origin. Evidence on the geochemical behavior of this component suggests that it was not derived from an actinide element (Z = 89 to 103), or from a transition metal between Z = 104 and 111, but from a more volatile progenitor. The most likely candidates are the superheavy elements between Z = 112 and 119, whose lighter congeners (mercury, tellurium, lead, and the like) are known to be strongly fractionated in meteorites.
