Abstract

Rull cave is placed in Vall d’Ebo (Alicante, SE Spain). It is a shallow karstic cavity which host rock is constituted by a Miocene limestone conglomerate unit, related to the Vall d´Ebo basin. The central room of the cavity is defined by a star-shaped dome and reaches nearly 30 m from de entrance door. The cave presents different kinds of carbonated speleothems: stalactites, stalagmites, flowstones, coralloidal speleothems, curtains and helictites. The most recent speleothems are related to: (i) “soda-straw” stalactites with more than 1m length; (ii) helictites and ‘frostwork’ speleothems with small size (0.5-5 cm) which cover irregularly other kind of speleothems, including curtains, stalactites, etc; and (iii) stalagmites and stalagmitic flowstones. Coralloidal are the most extended speleothems inside the cavity. They present a wide textural variability as: (i) botryoidal forms, covering stalagmitic flowstones or the gours bottom; (ii) globulites with different diameter, which cover zenital and parietal speleothems; (iii) branched speleothems developed over columns and stalagmitic flowstones. Predominant speleothems inside the cavity have a vadose origin. Their formation was driven by different mechanisms as drip water, capillarity, water flux, etc. All of the studied speleothems are calcitic (LMC) and they present textural variability. They change from white to almost red depending on their situation inside the cave as well as the host rock properties. Speleothems’ distribution and kind are totally influenced by the presence of karstic waters, their mineral composition and microclimatic conditions. These parameters are controlled by the host rock type and structure, external climate conditions and the distance to the surface.
