The Macanal Formation or Macanal Shale (Spanish: (Formación) Lutitas de Macanal, Kilm, K1m) is a fossiliferous geological formation of the Altiplano Cundiboyacense and Tenza Valley in the Eastern Ranges of the Colombian Andes. The predominantly formation dates to the Early Cretaceous period; Berriasian to Valanginian epochs and has a maximum thickness of 2,935 metres (9,629 ft). The Macanal Formation contains numerous levels of fossiliferous abundances. Bivalves, ammonites and fossil flora have been found in the formation.
The formation is a source rock for oil and gas in the Eastern Cordillera Basin and adjacent Llanos Basin foothills and provides emeralds in the vicinity of Macanal, after which the formation is named.
Etymology[]
The formation was defined and named in 1979 by Rodríguez and Ulloa after Macanal, Cundinamarca.[1][2] The name Macanal is either derived from the Muysccubun word Macana, meaning garrote, or from the Macana palm tree.[3][4]
Description[]
Lithologies[]
The Macanal Formation has a maximum thickness of 2,935 metres (9,629 ft), and is characterised by a sequence of micaceous ,[2] with calcite veins and gypsum occurrences intercalated in the formation. The Macanal Formation contains high values of TOC.[5] In the and the adjacent foothills of the Llanos Basin, the Macanal Formation is a source rock for oil and gas.[6] In the vicinity of Macanal, the formation provides emeralds.[7][8]
Stratigraphy and depositional environment[]
The Macanal Formation, a unit of the , concordantly overlies the Guavio, , , and ,[9] and is concordantly overlain by the Las Juntas Formation. The age has been estimated to be Berriasian to Valanginian. Stratigraphically, the formation is time equivalent with the , , Rosablanca, Murca and La Naveta Formations.[10] The formation has been deposited in a shallow marine environment in an enclosed basin,[5] with as provenance areas the Santander High and the Guiana Shield.[11] The Macanal Formation is part of the syn-rift sequence of eastern Colombia.[12]
Fossil content[]
The Macanal Formation contains numerous levels of fossiliferous abundances. Bivalves, ammonites and flora have been found in the formation.[13] Ammonites of , , , , Neocomites cf. wichmanni, Olcostephanus sp., Olcostephanus cf. atherstoni, , Acanthodiscus sp. have been registered in the formation, as well as bivalves of , Trigonia cf. hondana, Trigonia (Buchotrigonia) cf. abrupta, Trigonia (Notoscabrotrigonia) cf. tocaimaana, and Exogyra cf. boussingaulti.[14] Analysis of the deformation registered in ammonite fossils has helped in understanding the tectonic history of the Llanos foothills of the Eastern Ranges.[15]
Outcrops[]
The Macanal Formation is apart from its type locality in the canyon,[16][17] found in the Cravo Sur anticline, east of the Ocetá Páramo,[18] in the Desespero Synclinal in the southern and northern parts of Labranzagrande,[19][20] around Páez and Campohermoso,[17] in the eastern part of Gama, bordering the ,[21] and in the Servitá Synclinal, west of Villavicencio.[22] The Macanal Formation crops out along the road between Bogotá and Villavicencio and is there heavily fractured and folded. The Macanal Formation is the most extensive formation around Cáqueza,[23] and Gachalá, Cundinamarca.[24]
The thrusts the Macanal Formation on top of the Fómeque Formation to the east of Lake Tota,[25] and the thrusts the Macanal Formation on top of the overlying Las Juntas Formation around Chámeza, Casanare.[26] The forms the contact between the Fómeque Formation and the Macanal Formation,[27] while the puts the in contact with the Macanal Formation near Quetame,[28] as does the .[29] The forms the contact between the and the Macanal Formation,[30] and the , part of the same system puts the Macanal Formation in contact with the Tertiary .[31] At this contact, brines are extracted from the formation.[32]
