Zusammenfassung
The Castañar de Ibor Cave comprises a wide variety of speleothems which are undergoing recent diagenetic processes. Dissolution, micritization, inversion, cementation and dolomitization are the main ones. These processes are occurring now and in recent times and their study is a good model to understand ancient diagenetic processes in meteoric environments. The vadose waters are richin Mg because of the dissolution of Precambrian dolostones, favoring so the formation of aragonite and dolomitization. Changes in the water composition of the vadose fluids caused by possible variations in the climatic regime could control the diagenetic path.
