We use the triple oxygen isotope composition (O-17/O-16, O-18/O-16) of Proterozoic rocks to reconstruct the O-18/O-16 ratio of ancient meteoric waters. Some of these waters have originated from snowball Earth glaciers and thus give insight into the climate and hydrology of these critical intervals in Earth history. For a Paleoproterozoic [similar to 2.3-2.4 gigayears ago (Ga)] snowball Earth, delta O-18 = -43 +/- 3 parts per thousand is estimated for pristine meteoric waters that precipitated at low paleo-latitudes (<= 35 degrees N). Today, such low O-18/O-16 values are only observed in central Antarctica, where long distillation trajectories in combination with low condensation temperatures promote extreme O-18 depletion. For a Neoproterozoic (similar to 0.6-0.7 Ga) snowball Earth, higher meltwater delta O-18 estimates of -21 +/- 3% imply less extreme climate conditions at similar paleolatitudes (<= 35 degrees N). Both estimates are single snapshots of ancient water samples and may not represent peak snowball Earth conditions. We demonstrate how O-17/O-16 measurements provide information beyond traditional O-18/O-16 measurements, even though all fractionation processes are purely mass dependent."],["dc.identifier.doi","10.1073/pnas.1422887112"],["dc.identifier.isi","000353554000040"],["dc.identifier.pmid","25870269"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/37341"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.relation.issn","0027-8424"],["dc.title","Revealing the climate of snowball Earth from Delta O-17 systematics of hydrothermal rocks"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dspace.entity.type","Publication"]]

This includes asteroids that are not otherwise represented in our meteorite collections. In this work we obtained 3D images of micrometeorite interiors using tomography before collecting destructive high-precision oxygen isotope measurements. These data allow us to link textures in unmelted micrometeorites to known chondrite groups. In addition to identifying particles from ordinary chondrites, CR and CM chondrites we report two micrometeorites derived from an anomalous 16O-poor source (δ17O: +16.4‰, δ18O: +28.4‰, and Δ17O: +1.4‰). Their compositions overlap with a previously reported micrometeorite (TAM50-25) from Suttle et al. (2020), https://doi.org/10.1016/j.epsl.2020.116444 (EPSL: 546:116444). These particles represent hydrated carbonaceous chondrite material derived either from a new group or from the CY chondrites (thereby extending the isotopic range of this group). In either scenario they demonstrate close petrographic and isotopic connections to the CO-CM chondrite clan. Furthermore, their position in O-isotope space makes them the most likely candidate for the parent body of the anomalous “group 4” cosmic spherules previously reported by Suavet et al. (2010), https://doi.org/10.1016/j.epsl.2010.02.046 (EPSL: 293:313-320) and several subsequent isotopic studies.

The silicate melt-H2O vapor exchange experiments were carried out in a vertical gas-mixing furnace using the metal loop technique at 1500 degrees C. The duration ranged from 5 to 1440 min and fO(2) was set between IW - 3.8 and IW - 1.3 using the H2O/H-2 buffer. Our experiments show that 50% exchange between H2O gas and silicate melt occurs in similar to 4 h at fO(2) = IW -3.8 and in similar to 1 h at fO(2) = IW - 1.3. At solar nebula conditions, significant exchange occurs only if chondrule-melting times were several hours. (C) 2015 Elsevier Ltd.

We report the detection of all major presolar grain types with O- and C-anomalous isotopic compositions typically identified in carbonaceous chondrite meteorites: 1 silicate, 1 oxide, 1 O-anomalous supernova grain of ambiguous phase, 38 SiC, and 16 carbonaceous grains. At least two of the carbonaceous grains are presolar graphites, whereas several grains with moderate C isotopic anomalies are probably organics. The presolar silicate was located in a clast with a less altered lithology than the typical extensively aqueously altered Ryugu matrix. The matrix-normalized presolar grain abundances in Ryugu are \r\n \r\n\r\n\r\n 4.8−2.6+4.7\r\n \r\n ppm for O-anomalous grains, \r\n \r\n\r\n\r\n 25−5+6\r\n \r\n ppm for SiC grains, and \r\n \r\n\r\n\r\n 11−3+5\r\n \r\n ppm for carbonaceous grains. Ryugu is isotopically and petrologically similar to carbonaceous Ivuna-type (CI) chondrites. To compare the in situ presolar grain abundances of Ryugu with CI chondrites, we also mapped Ivuna and Orgueil samples and found a total of 15 SiC grains and 6 carbonaceous grains. No O-anomalous grains were detected. The matrix-normalized presolar grain abundances in the CI chondrites are similar to those in Ryugu: \r\n \r\n\r\n\r\n 23−6+7\r\n \r\n ppm SiC and \r\n \r\n\r\n\r\n 9.0−3.6+5.4\r\n \r\n ppm carbonaceous grains. Thus, our results provide further evidence in support of the Ryugu–CI connection. They also reveal intriguing hints of small-scale heterogeneities in the Ryugu samples, such as locally distinct degrees of alteration that allowed the preservation of delicate presolar material."],["dc.description.sponsorship","NASA"],["dc.description.sponsorship","NASA"],["dc.identifier.doi","10.3847/2041-8213/ac83bd"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/112750"],["dc.language.iso","en"],["dc.relation.eissn","2041-8213"],["dc.relation.issn","2041-8205"],["dc.rights","CC BY 4.0"],["dc.rights.uri","http://creativecommons.org/licenses/by/4.0/"],["dc.title","Presolar Stardust in Asteroid Ryugu"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
