摘要

Cluster structures of O-16,O-18 and O-20 are investigated using the antisymmetrized molecular dynamics (AMD) plus generator coordinate method (GCM). We have found the K-pi=0(2)(+) and 0(-) rotational bands of 180 that have prominent C-14+alpha cluster structure. The clustering systematics are richer in O-20. We suggest the presence of a K-pi=0(2)(+) band that is a mixture of the C+alpha+4n and C-14+He-6 cluster structures. K-pi=0(3)(+) and 0(-) bands that have prominent C-16+alpha cluster structure are also found.

On the Use of Dissolved Oxygen Isotopologues as Biogeochemical Tracers in the Northeast Pacific Ocean

Boda Li, Huanting Hu, William M. Berelson, Jess F. Adkins, Laurence Y. Yeung

Summary: The isotopic composition of dissolved oxygen can be used as a tracer for respiration and transport in the subsurface ocean. However, uncertainties in transport parameters and isotopic fractionation factors limit its effectiveness. In this study, new data and a model were used to investigate the oxygen isotopologues in the subsurface Pacific. The results suggest that the traditional isotopic fingerprints associated with oxygen consumption in the Pacific Ocean may need to be reexamined.

How 17O excess in clumped isotope reference-frame materials and ETH standards affects reconstructed temperature

Casey P. Saenger, Andrew J. Schauer, Emma O. Heitmann, Katharine W. Huntington, Eric J. Steig

Summary: The study evaluates the assumptions made in Delta(47) measurements by analyzing Delta O-17 in reference frame materials and standards. The results show that assuming Delta O-17 = 0 can lead to overestimation or underestimation of Delta(47) values, depending on the sample's Delta O-17 relative to the working gas. This effect can introduce significant errors in reconstructed temperatures, emphasizing the importance of considering Delta O-17 for accurate Delta(47) thermometry.

Variability and Controls on δ18O, d-excess, and increment ′17O in Southern Peruvian Precipitation

Phoebe G. Aron, Christopher J. Poulsen, Richard P. Fiorella, Naomi E. Levin, Rene P. Acosta, Brian J. Yanites, Elizabeth J. Cassel

Summary: The study presents a three-year record of isotopic variability in central Andean precipitation, highlighting the negative correlation between elevation and delta O-18(p) values. Results show that seasonal variations in delta O-18(p) are influenced by upstream rainout and local convection. Both eastern- and western-derived air masses contribute to precipitation in southern Peru, and seasonal d-excess(p) cycles record moisture recycling and relative humidity at remote moisture sources.

NanoSIMS as an analytical tool for measuring oxygen and hydrogen isotopes in clay minerals from palaeosols: Analytical procedure and preliminary results

Elisa Laita, Maria Angels Subirana, Dirk Schaumloffel, Alfonso Yuste, Blanca Bauluz

Summary: The oxygen and hydrogen isotope composition of neoformed clay minerals in palaeosol samples were analyzed using NanoSIMS. The results showed that the technique is effective in determining the isotopic composition of the minerals and can be used to estimate past climatic conditions. This study demonstrates the potential applicability of NanoSIMS in palaeoclimatic research.

In situ carbon and oxygen isotopes measurements in carbonates by fiber coupled laser diode-induced calcination: A step towards field isotopic characterization

Christophe Thomazo, Pierre Sansjofre, Olivier Musset, Theophile Cocquerez, Stefan Lalonde

Summary: The study introduces a new protocol for carbonates analysis using a laser calcination system, which reduces preparation steps and analysis time significantly while offering spatially resolved analysis at the mm scale. The new method based on a fiber-coupled laser diode device shows accurate and reproducible results for C and O isotopic characterization of natural carbonates. The study also demonstrates that physical effects during calcination do not introduce isotopic fractionation for C and a constant isotopic offset for O within a range of isotopic compositions and mineral matrices.

The role of cave ventilation in the triple oxygen and hydrogen isotope composition of condensation waters in Altamira Cave, northern Spain

Fernando Gazquez, Luis Quindos, Daniel Rabago, Ismael Fuente, Santiago Celaya, Carlos Sainz

Summary: This study investigates the isotopic compositions of condensation water in Altamira Cave and finds that condensation water in the outer cave sectors show higher isotopic values during the cave ventilation period, while condensation water in the inner cave sectors have similar isotopic values with infiltration water and insignificant seasonal variability. These results are important for the management of Altamira Cave and for future investigations on condensation mechanisms in cavities elsewhere.

Male mastodon landscape use changed with maturation Pleistocene, North America)

Joshua H. Miller, Daniel C. Fisher, Brooke E. Crowley, Ross Secord, Bledar A. Konomi

Summary: Under harsh Pleistocene climates, migration and seasonally patterned landscape use were critical for reproductive success of mastodons and other megafauna. Using isotopic analysis of a mastodon tusk, researchers found that the geographic ranges and mobility of the mastodon changed as it matured, with an increase in movement and the development of seasonal landscape use. The mastodon's death in northeast Indiana suggests that this area may have been important for mating and had regional significance for late Pleistocene mastodons.

Significance of 56Fe depletions in late-Archean shales and pyrite

Chadlin M. Ostrander, Silke Severmann, Gwyneth W. Gordon, Brian Kendall, Timothy W. Lyons, Wang Zheng, Moutusi Roy, Ariel D. Anbar

Summary: Research indicates that sedimentary rocks and minerals formed during the late Archean Eon contain lower levels of Fe-56 compared to other periods, possibly due to factors such as very negative seawater delta Fe-56 values, shuttling of light Fe isotopes in redox-stratified environments, and pyrite formation in Fe(II)-rich oceans. These processes, along with evidence of Fe shuttle and pyrite formation, likely played a role in driving strong 56Fe depletions. The connection between severe Fe-56 depletions and distant euxinic settings suggests a persistent presence of a very negative global seawater delta Fe-56 value during the latest Archean, supporting the idea of a prolonged initial oxidation process on Earth.

Triplet Spin-State Capped Deltahedral Structures Rather than Singlet Spin-State Oblatocloso Structures as Energetically Favored Dimanganaborane Structures

Artiom Gaina-Gardiuta, Alexandru Lupan, R. Bruce King

Summary: Density functional theory studies suggest that high-spin triplet and quintet structures are energetically favorable for dimanganaboranes of first-row manganese, while flattened singlet structures are preferred for dimetallaboranes of third-row rhenium. The different peference might be attributed to the ligand field splittings in complexes of manganese and rhenium.

Helium and oxygen isotopic variations in the Iceland plume source controlled by entrainment of recycled oceanic lithosphere

Maja B. Rasmussen, Saemundur A. Halldorsson, Matthew G. Jackson, Ilya N. Bindeman, Martin J. Whitehouse

Summary: Icelandic basalts have low oxygen isotope (δO-18) values, which may be attributed to the combination of crustal assimilation and mantle characteristics, with the latter being more significant. Measurements and analysis of olivine crystals from the Iceland hotspot, covering 16 Ma of activity, reveal that low δO-18 values are related to crustal processes. By filtering out data influenced by crustal assimilation, it is concluded that the low δO-18 values are derived from the Iceland mantle. Additionally, the study finds that the low δO-18 and low He-3/He-4 components have become increasingly apparent in the modern Iceland mantle, possibly due to enhanced mantle melting.

Simultaneous Production and Consumption of Soil N2O Creates Complex Effects on Its Stable Isotope Composition

Ronald Amundson, Jennifer V. Mills, Laura N. Lammers, Matti Barthel, Nora Gallarotti, Johan Six, Gerhard Gebauer, Greg E. Maurer

Summary: The stable isotopes of nitrogen (N) and oxygen (O) in soil and soil-respired N2O are being measured, but there is a lack of theoretical framework to interpret the data. This study uses a diffusion/reaction model to demonstrate how soil processes influence the profiles and fluxes of soil N2O and its isotopes. The results suggest that the isotope composition of soil N2O flux is dependent on the net flux rate and the difference in isotope composition between the atmosphere and the biological source.
