Neptunian dikes along submarine escarpments : examples from the Jurassic of Monte Kumeta (Sicily)
  • Neptunian dikes along submarine escarpments : examples from the Jurassic of Monte Kumeta (Sicily)
  • Biostratigraphy ; Dyke ; Italy ; Jurassic ; Mesozoic ; Regional geology ; Sicilia ; Tectonics
  • Along the Jurassic escarpment of Monte Kumeta (western Sicily), the opening of neptunian dikes is related either to extensional tectonics or to dilatation due to down-slope sliding. Crosscutting relationships coupled with biostratigraphic data
  • indicate that at least three generations of fractures formed Early to Middle Jurassic times. - (NF)
Early development of Tethys and Jurassic ophiolite displacement
  • Early development of Tethys and Jurassic ophiolite displacement
  • The apparent ages (Ar-Ar) suggest that initial oceanic plate disruption and tectonic emplacement of the Zagros and Makran ophiolites occurred in the middle Jurassic (170 Myr ago) with further displacements in the late Cretaceous (97 Myr and 89 Myr
  • ago). The similarity of the Jurassic age with ophiolite emplacement ages in Yugoslavia and Greece is possible evidence of a middle Jurassic collision of an early Mesozoic Tethyan ridge system with both eastern Europe and central Asia.
Jurassic carbonate depositional systems of the Mt. Catria-Mt. Acuto area (Umbria-Marche Apennines, Italy)

  • A geologic survey, integrated with sedimentalogic observations and macrofacies analysis, has been carried out for the Jurassic deposits outcropping in the Mt. Catria - Mt. Acuto area. The study area is located within the northern Umbria-Marche
  • Apennines and is characterized by the presence of Jurassic different type successions that reflect depositional environment variability. The aim of this paper is to reconstruct the Jurassic paleographic structural setting and the paleotectonic evolution
  • of the area. The data obtained allowed for the identification of two isolated, uplifted blocks of the carbonate platform (Corno di Catria and Mt. Acuto), reduced in size, bounded by escarpments of tectonic origin and separated by a narrow Jurassic basinal area

Dinosaur tracks in a marginal marine environment : the Coste dell’Anglone ichnosite (Early Jurassic, Trento Platform, NE Italy)

  • Bipedal tridactyl dinosaur footprints dominate the Early Jurassic Coste dell’Anglone tracksite, located on the eastern slope of the Mt. Biaina-Mt. Brento chain (Trentino Alto-Adige, NE Italy). The site yielded 544 tridactyl footprints, arranged
  • deposited in a marginal area of the Trento carbonate Platform, which has so far been considered fully marine (subtidal) in origin. The Coste dell’Anglone outcrop represents one of the most extensive Early Jurassic dinosaur tracksites in the Southern Alps
  • and is probably the last dinosaur occurrence on the Trento Platform. This new discovery therefore supports calls for a re-examination of the palaeogeographic reconstruction of the Southern Alps during the Early Jurassic. - (NF)

The protection potential of soils and post-Jurassic covers against nitrate seepage (Southern Franconian Jura, Germany)
  • The protection potential of soils and post-Jurassic covers against nitrate seepage (Southern Franconian Jura, Germany)
  • The mid-mountain plateau of the Southern Franconian Jura exhibits base rocks of bedded and massive Upper Jurassic (Malm) carbonate rocks. These only provide a low protection potential against nitrate seepage. Hence, post-Jurassic covers may play
