Advancing Cave Survey Methods
Cave floor mapping plays a vital role across various scientific disciplines by enabling the identification and interpretation of features shaped by both natural processes and human activity. In cave archaeology, floor mapping is crucial to decode and reconstruct human‐induced morphological features. However, the field has long faced significant challenges in accurately mapping the complexity of cave systems. Conventional methods often fail to cap…
Isotope and trace element evolution of the naica aquifer (Chihuahua, Mexico) over the past 60,000 yr revealed by speleothems
The “espada” speleothems of Cueva de las Espadas (Naica Mine, Chihuahua, Mexico) comprise a high-purity selenite core overlain by successive deposits of calcite, gypsum and aragonite. Gypsum precipitated under water from a hydrothermal solution (~ 58°C) when the water table was above the cave level ca. 57 ka, during the last glaciation, and some intervals during deglaciation and the Holocene. Aragonite was deposited at lower temperatures (~ 26°C)…
Glacier advances during the last 400ka as evidenced in St. Beatus Caves (BE, Switzerland)
Late Quaternary environmental and human Events at En Gedi, reflected by the geology and archaeology of the Moringa Cave (Dead Sea area, Israel)
The Moringa Cave within Pleistocene sediments in the En Gedi area of the Dead Sea Fault Escarpment contains a sequence of various Pleistocene lacustrine deposits associated with higher-than-today lake levels at the Dead Sea basin. In addition it contains Chalcolithic remains and 5th century BC burials attributed to the Persian period, cemented and covered by Late Holocene travertine flowstone. These deposits represent a chain of Late Pleistocene …
Stable isotope variations in stalagmites from northwestern Sweden document climate and environmental changes during the early Holocene
This paper presents two early Holocene (9.6-5.9 ka BP) high-resolution stable isotope records of stalagmites from two caves in northwestern Sweden (Korallgrottan and Labyrintgrottan). Close similarities between the Swedish records and a previously presented Norwegian stalagmite oxygen isotope record emphasize the potential of Scandinavian stalagmites to provide high-resolution regional palaeoclimatic information. The stable oxygen isotope records…
Uranium series dates from Qesem Cave, Israel, and the end of the Lower Palaeolithic
Comparison of the Climate during Marine Isotope Stage 9 and 11 Inferred from a Speleothem Isotope Record from Northern Norway
A stalagmite from northern Norway is dated with 12 thermal ionization mass spectrometry U-Th dates, and at least four separate growth periods are identified that correspond with marine isotope stages 9, 11, 13, and probably 15. The calcite is tested for isotopic equilibrium with the Hendy test. Oxygen isotope measurements on 231 subsamples on a vertical transect are used as a paleotemperature proxy. The detailed isotopic record from MIS 9 show ap…
Stable Isotope Stratigraphy of a Late Last Interglacial Speleothem from Rana, Northern Norway
A stalagmite from Rana, northern Norway, dated by the TIMS uranium-series technique, yields records of stable oxygen and carbon isotopes covering the period from late marine oxygen isotope substages (MIS) 5e to 5a, that is, 123,350 to 73,300 yr ago. Rapid growth (∼46 μm/yr) between 123,350 and 119,500 yr ago reflects climatic conditions favorable for speleothem growth. This period is characterized by century- to millennial-scale oscillations in b…
Calibration of the speleothem delta function
The speleothem delta function (SDF) provides a new transfer function between the d 18 O signal of speleothem calcite and surface ground temperature. The function is based on physical principles, relating d 18 O of the calcite to thermodynamic fractionation, and to the dripwater function, which in turn relates d 18 O of dripwaters to that of the local precipitation and thus to the modification of source water in relationship to the geographical po…
A 3000-year high-resolution stalagmitebased record of palaeoclimate for northeastern South Africa
High-resolution stable isotope variations and growth structure analyses of the last three millennia of a 6600-year stalagmite record at Cold Air Cave, Makapansgat Valley, South Africa, are presented. Growth layers, which are measurable over the last 250 years, are shown to be annual. The correlation between the width of growth layers and precipitation is strongly positive. Changes inδ 18 O andδ 13 C are positively correlated and inversely correla…
Speleothems and climate
Speleothems (cave dripstones) are formed as a part of the meteoric water cycle and therefore vari ations in their growth rate and composition reflect environmental changes on the land surface above the cave. Since they are continental deposits, and possess a remarkably accurate dating potential, using TIMS U-series techniques, speleothems are important palaeoclimatic archives for the terrestrial environment, complementing the marine and ice-core …
High-Resolution Paleotemperature Proxy Record for the Last Interglaciation Based on Norwegian Speleothems
Two speleothems from a coastal lowland and an alpine cave site in northern Norway grew in isotopic equilibrium during Termination II and marine isotope stage 5 (150,000-80,000 yr B.P.), as dated by the U-series technique. The stable isotope record (δ 18 O, δ 13 C) displays a time resolution down to ∼20 yr. The δ 18 O c signal in the two speleothems appears to be mainly dominated by the meteoric signal; i.e., there is a positive relationship betwe…

Geochronological Potential of Isoleucine Epimerization in Calcite Speleothems
The extent of isoleucine epimerization in a calcite speleothem was determined to evaluate the amino acid racemization method in abiotic calcite. A 5.5-cm-thick flowstone slab from Hamarnesgrotta, northern Norway, was analyzed for amino acid concentration, composition, and isoleucine epimerization at 26 levels through the sequence. U-series dates provide an independent chronologic control. Epimerization increases monotonically with stratigraphic d…
Paleoclimate Deduced from a Multidisciplinary Study of a Half-Million-Year-Old Stalagmite from Rana, Northern Norway
A 7-cm-thick flowstone sequence has been dated by extended Uranium series techniques to less than 1.25 myr, with a probable growth interval of ≥350,000–≤730,000 yr B.P. The time span is in accordance with paleomagnetic results revealing normal polarity for the whole sequence, i.e., a depositional age of
