PPP# 1306 - Cativa [lower Gatun Fm] (Miocene of Panama)

Also known as NMB Loc. 18390

Where: Colon, Panama (9.4° N, 79.8° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: lower 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 member of the Gatun Formatio according to the author; the enterer considers this to be the lower member of the Gatun Formation.

• bed-level stratigraphic resolution

Environment/lithology: coastal; unlithified, gray siltstone and unlithified, bioturbated sandstone

• ENVIRONMENT: from Collins et al. (1999), open, inner neritic.
• GENERAL LITHOLOGY: The lower 5m of the lower Gatun Formation consists of volcanic conglomerate, with 1-5cm clasts and a tuffaceous, arkoskic matrix, cross-bedded, laminated, tuffaceous siltstone and alternating laminated sandstone and siltstone, mostly deeply weathered. The overlying 40m (Section 1) consists of massive, grey-green, clayey siltstone, with minor claystone and fine sandstone units. zones of densely packed large concretions, pervasive bioturbation, and extensive thalassinoid burrow systems, as well as simple vertical and lateral hash-filled burrows. Shell hash of varying grain size and density is almost ubiquitous, as are units packed with diverse, whole mollusks.

Size class: macrofossils
