Caracterización de la Formación Villar del Arzobispo al sur de Zaragoza (Titónico, Cordillera Ibérica)
The Villar del Arzobispo Formation (middle Tithonian–lowermost Berriasian) has been recognized for the first time in the two classical outcrops of Villanueva de Huerva and Aguilón (Zaragoza, nor thern Iberian Chain). It consists of a 40-70 m thick detritial succession, with scarce carbonate levels (...

| Sumario: | The Villar del Arzobispo Formation (middle Tithonian–lowermost Berriasian) has been recognized for the first time in the two classical outcrops of Villanueva de Huerva and Aguilón (Zaragoza, nor thern Iberian Chain). It consists of a 40-70 m thick detritial succession, with scarce carbonate levels (ooidal and skeletal packstone with echinoderms, miliolids and other marine fossils). In previous works, this uppermost Jurassic unit was considered to form the lower part of the Villanueva de Huerva Formation (late Valanginian- Hauterivian). However, a low-angle angular unconformity between the Villar del Arzobispo and Villanueva de Huerva formations is described here. The new interpretation gives an explanation to the occasional marine influence observed in the nearby Cameros basin (i.e., Matute Formation, middle–upper Tithonian) |
