• Resumen

  • The Miocene Bateig Stone is a biocalcarenite quarried near Novelda (Alicante). Bioturbation is very intense in most of the sedimentary succession obliterating primary sedimentary structures. The study of the bioturbation has led to the definition of four distinctive ichnofabrics, tus allowing to reconstruct the ichnostratigraphy of the section. Although ichnofabrics, sedimentology and grain size are suggestive of sedimentation in shallow water environments, the abundance of pelagic microfossils seems indicative of a rather deeper setting. Nevertheless, the Bichordites ichnofabric found in Bateig is also known from other Neogene deposits with mixed bathymetric signals, which are interpreted as formed in a relatively deep paleostrait where enhancement of tidal currents took place. A similar setting is here proposed for the deposition of the Bateig Stone.
