Resumen
Samples of siliceous speleothems, deposited in small rock shelters featuring a high availability of quartz, have been taken from a total of seven outcrops located in Extremadura and western Andalusia. The study of these deposits is currently generating important and relevant information about the first stages of formation of this type of speleothem, as well as other related aspects of the unique ecosystem that develops within them. Of note is the presence of photosynthetic diatoms, which, unlike in speleothems deposited in large caves, constitute the pioneer phase of their development. Also worthy of mention is a type of testate amoebae with xenogenous test, which seems to be characteristic of these deposits originally made by polimineralic clasts.
