Zartman, R.E., and Howard, J.M., 1987, Uranium-lead age of large zircon crystals from the Potash Sulfur Springs igneous complex, Garland County, Arkansas, IN Morris, E.M., ed., Mantle metasomatism and alkaline magmatism: Geological Society of America Special Paper, 215, p. 235-240.


Summary:

Age defined by uranium-lead isotope dating of zircon crystals from weathered syenite as 100 +/-2 Ma, near end of Albian. Age agrees with published age of nearby Magnet Cove Complex, attesting to contemporaniety.
