Franklin Island is a 2 x 7.6 km remnant of a shield volcano whose vent was located to the east. IAVCEI (1973) assigns a Quaternary age. The only radiometric date available is a Potassium-Argon date of 4.8 +/- 2.0 Ma (LeMasurier and Thomson 1990). Bathymetric mapping in 2004 identified the Franklin Volcanic Field, a regional high with clusters of submarine cones extending 80 km long and up to 40 km wide (Smith, 2004).
