These lidites were derived from submarine vents as a consequence of hydrothermal-sedimentary processes. The paper examines the sedimentological characteristics of lidites, studies the different types of associated synsedimentary folds and offers criteria for distinguishing lidites which take root in a vent (first type) from those which were glided through a paleoslope (second type).10 p.application/pdfspa(c) Gimeno Torrente, Domingo, 1986Roques silíciquesPaleozoicSardenya (Itàlia)Siliceous rocksPaleozoicSardinia (Italy)info:eu-repo/semantics/article0247512012-12-03info:eu-repo/semantics/openAccess
