| Brief content | Topolnița Cave (Mehedinți Mountains, SW Romania) is one of the longest and most spectacular karst caves in Romania. It develops on four levels and several galleries with a great variety of speleothems, also hosting a large bat colony. Sediments in caves can offer site-specific data related to bedrock, paleoclimate, geomorphic and diagenetic processes, together with data on anthropic processes outside the cave. The aim of the study was to assess the seasonal variation of the chemistry and mineralogy of this cave sediments. Alluvial pre-Holocene (older than 11,500 y) sediment samples were collected from the cave floor in two sampling stations during a four-season survey in 2019. The mineralogy of samples showed the dominance of silicates over carbonates. The mineralogical association shows allogenic origin of sediments. |
