The Cova des Pas de Vallgornera is an important and protected coastal cave, located in the southern part of the island of Mallorca, that outstands due to its length and the complex processes involved in its speleogenesis. Although sediments are not the main topic of interest, their presence as well as their paleontological contents are valuable evidence for paleoclimatic and chronological reconstructions of the cave morphogenesis. The sedimentary infilling is characterized by a scarce presence of clastic sedimentation, mainly composed of silts and clays, which can only be found at some minor passages in the innermost parts of the cave. It corresponds to a clayey sedimentation mainly derived from the soil infiltration that can be found mixed with carbonate particles detached from the cave walls. A particularly different situation occurs in the northernmost end of the cave where an important sequence of silty sands are present, hosting a very rich paleontological deposit. The objective of this paper is to describe the detrital deposits present in the cave by means of the integration of sedimentological, chemical, and mineralogical data, which will aim to provide a better understanding of the processes that have occurred during the system’s speleogenetic evolution.
