Multiple sediment proxies from Jaraguá cave, Brazil
2019
Multiple paleoclimate, paleovegetation and paleoenvironmental records from Jaraguá cave, located at center of South America. In this dataset that covers the last 28,000 year is included δ13C and δ18O values and 87Sr/86Sr ratios in stalagmites combined with XRF-derived elemental chemistry, δ13Corg, total organic carbon and total inorganic carbon (carbonate) in a sedimentary profile from the same cave.
Effects of glaciation on karst hydrology and sedimentology during the Last Glacial Cycle: The case of Granito cave, Central Pyrenees (Spain)
2021
In Alpine regions, speleothem development on karst systems largely occurs during warm interglacial or interstadial phases due to their limited growth during cold stages. Still, recent attention has been given to the role of clastic sediments in caves, less dependent on temperature conditions. Yet, only a small number of caves worldwide preserve both speleothems and detrital deposits. Here we present an outstanding record of fine-grain laminated sediments and carbonate speleothems from the Granito cave (South Central Pyrenees, Spain) associated with seasonal to annual hydroclimatic pulses through the Last Glacial Cycle (LGC). Analysis of cave clastic facies together with new absolute dates o…
