    • Characterization and Correction of Evaporative Artifacts in Speleothem Fluid Inclusion Isotope Analyses as Applied to a Stalagmite From Borneo 

      Fernandez, A; Loeland, Marit Holten; Maccali, Jenny; Krüger, Yves Stephan; Vonhof, Hubert; Sodemann, Harald; Meckler, Anna Nele (Journal article; Peer reviewed, 2023)
      Fluid inclusion water isotope measurements in speleothems have great potential for paleoclimate studies as they enable the reconstruction of precipitation dynamics and land temperatures. Several previous observations, ...

    • Evolution of tropical land temperature across the last glacial termination 

      Løland, Marit Holten; Krüger, Yves Stephan; Fernandez, Alvaro; Buckingham, Frances; Carolin, Stacy A.; Sodemann, Harald; Adkins, Jess F.; Cobb, Kim M.; Meckler, Anna Nele (Journal article; Peer reviewed, 2022)
      The tropical West Pacific hosts the warmest part of the surface ocean and has a considerable impact on the global climate system. Reconstructions of past temperature in this region can elucidate climate connections between ...

    • Geothermometry of calcite spar at 10–50 °C 

      Koltai, Gabriella; Kluge, Tobias; Krüger, Yves Stephan; Spötl, Christoph; Rinyu, László; Audra, Philippe; Honiat, Charlotte; Leél-Őssy, Szabolcs; Dublyansky, Yuri (Journal article; Peer reviewed, 2024)
      Carbonate geothermometry is a fundamental tool for quantitative assessment of the geothermal and geochemical evolution of diagenetic and hydrothermal systems, but it remains difficult to obtain accurate and precise formation ...

    • Late-stage evolution of hypogene caves at Tyuya-Muyun (Kyrgyzstan): Quantitative insights from mineral deposits 

      Koltai, Gabriella; Spötl, Christoph; Rinyu, László; Honiat, Charlotte; Racine, Tanguy; Zhang, Haiwei; Krüger, Yves Stephan; Dublyansky, Yuri (Journal article; Peer reviewed, 2024)
      The Tyuya-Muyun massif in SW Kyrgyzstan hosts a number of caves some of which contain Ra- and U-bearing minerals that were extensively mined in the early 20th century. Previous studies have suggested that the caves of the ...

    • Multi-proxy speleothem-based reconstruction of mid-MIS 3 climate in South Africa 

      Maccali, Jenny Marianne; Meckler, Anna Nele; Lauritzen, Stein Erik; Brekken, Torill; Rokkan, Helen Aase; Bremer, Alvaro Fernandez; Krüger, Yves Stephan; Adigun, Jane; Affolter, Stéphane; Leuenberger, Markus (Journal article; Peer reviewed, 2023)
      The southern coast of South Africa displays a highly dynamical climate as it is at the convergence of the Atlantic and Indian oceans, and it is located near the subtropical/temperate zone boundary with seasonal influence ...

    • Nucleation-assisted microthermometry: A novel application to fluid inclusions in halite 

      Arnuk, William D.; Guillerm, Emmanuel; Lowenstein, Tim K.; Krüger, Yves Stephan; Olson, Kristian J.; Lensky, Nadav G.; Brauer, Achim (Journal article; Peer reviewed, 2024)
      Halite deposits have long been utilized for interrogating past climate conditions. Microthermometry on halite fluid inclusions has been used to determine ancient water temperatures. One notable obstacle in performing ...

    • World-class amethyst-agate geodes from Los Catalanes, Northern Uruguay: genetic implications from fluid inclusions and stable isotopes 

      Arduin-Rode, Fiorella; Sosa, Graciela; van den Kerkhof, Alfons; Krüger, Yves Stephan; Bajnai, David; Pack, Andreas; Di Rocco, Tommaso; Oyhantçabal, Pedro; Wemmer, Klaus; Herwartz, Daniel; Klipsch, Swea; Wiegand, Bettina; Siegesmund, Siegfried; Hueck, Mathias (Journal article; Peer reviewed, 2024)
      The amethyst and agate geodes from the Los Catalanes Gemmological District in Uruguay represent one of the main deposits of its kind worldwide. The geometry of the deposit is horizontal, with an irregular distribution of ...
