Geochronology of the Arkanas Alkaline Province, Southeastern United States [PDF]
, 2009 The Arkansas alkaline province (AAP) consists of intrusive bodies ranging in lithology from carbonatite and lamproite through nepheline syenite. Apatite and titanite fission-track ages fall into two groups-101-94 Ma and ∼88 Ma.

Local Phenomena in meta-mict Titanite
Acta Physica Polonica A, 2010 Pure titanite is a mineral with chemical composition CaTiSiO5. Its structure consists of corner linked TiO6-octahedra, SiO4-tetrahedra and sevenfold coordinated Ca positions. In nature various impurities like U and Th can be incorporated in the structure showing alpha and beta radiation.
