| Sumario: | The aims of the present work are: i) the description of the Miocene deposits cropping out in the Nueva Tabarca island; ii) the characterization of the use of these rocks in the local heritage; and iii) the analysis of the rock behaviour during weathering processes. The Miocene stratigraphic succession can be divided into three parts. The first one shows dolomite-rich sandstones interbedded to biocalcarenites rich in corals, red algae, thick-shelled bivalves and clypeasteroids. The second part corresponds to cross-laminated calcirudites whose top is represented by a condensed level rich in large bioclasts and rhodolites, passing upward to fine-grained sandstones. The third part begins with several hardened levels of sandstones followed by fine-grained parallel-laminated sandstones. Ancient quarries were located at every level of the stratigraphic series. Consequently, every lithofacies are observed in the current ashlars of the monuments. These rocks are easily decayed by means of granular disintegration, flakes and/or alveolar weathering |
