Gatun Locks [upper Gatun Fm] (Miocene of Panama)

Where: Panama (9.3° N, 79.9° W: paleocoordinates 9.1° N, 78.5° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: upper Gatun Member (Gatun Formation), Tortonian (11.6 - 7.2 Ma)

• STRATIGRAPHIC RELATIONS: From the Gatun Fm, which regionally overlies the Caimito Fm or Mesozoic basement. AGE: Late Miocene. STRATIGRAPHIC POSITION: From middle-upper member of the Gatun Formation according to the author; the enterer considers this to be the upper member of the Gatun Formation.
