Stratigraphy comments: The Caimito Formation in Madden Basin includes both Oligocene and lower Miocene deposits. The thickness in the basin appears to be 450 m. The deposits now referred to the Caimito Formation were initially designated the Culebra Formation, Emperaqdor Limestone, Caimito Formation, and Gatun Formation. Five members are tentatively recognized in the Caimito Formation. Two members are grouped as the lower part, the upper three members form the upper part. In stratigraphic order these include: basal calcareous sandstone-siltstone member (200 m) overlies the Bohio Formation, or laps onto the Gatuncillo Formation; the pyroclastic-clay member (50 m); Chilibrillo Limestone member (150 m); calcareous sandstone member (30 m); Alhajuela Sandstone member (85 m). The lower part of the Caimito Fm (2 basal members) is late Oligocene, the upper part (3 upper members) is early Miocene; Alhajuela Sandstone revised to formation rank in subsequent publications. |
