The Metallogenic Age of the Ovor Bayan Molybdenum Deposit in Southeastern Mongolia: Constraints from SHRIMP Zircon U-Pb and Molybdenite Re-Os Geochronology

Applied Sciences
The Ovor Bayan molybdenum deposit in Mongolia is located within the western segment of the Nukhetdavaa–Erlianhot–Dongwuzhumuqin–Aershan Mo–Pb–Zn–W–Cu–Sn–Cr–Fe metallogenic belt in the Mongolia–Daxing’anling Metallogenic Province.

Basinal restriction, black shales, Re‐Os dating, and the Early Toarcian (Jurassic) oceanic anoxic event [PDF]

Paleoceanography, 2008
Profiles of Mo/total organic carbon (TOC) through the Lower Toarcian black shales of the Cleveland Basin, Yorkshire, United Kingdom, and the Posidonia shale of Germany and Switzerland reveal water mass restriction during the interval from late tenuicostatum Zone times to early bifrons Zone times, times which include that of the putative Early Toarcian ...

Neuropsychological and Educational Outcomes in Shwachman–Diamond Syndrome—A Report From the North American Shwachman–Diamond Syndrome Registry

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Shwachman–Diamond syndrome (SDS) is a rare autosomal recessive ribosomopathy characterized by bone marrow failure and multisystem involvement, with emerging evidence of associated neurocognitive impairment. Methods We conducted a retrospective study of 240 individuals with biallelic Shwachman–Bodian–Diamond syndrome (SBDS) mutations

Re-Os Chronology and Systematics of Graphite

, 2023
Graphite-forming events occurred throughout Earth history and extend up to solar and pre-solar contexts. However, a comprehensive understanding of the timeline of these events has been hindered by a lack of chronological information for graphite. Here we

Beyond the Document: A Single‐Center Qualitative Study of Survivorship Care Plan Barriers and Opportunities Across Pediatric Oncology Stakeholders

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survivorship care plans (SCPs) summarize cancer treatment and guide risk‐based follow‐up for cancer survivors, yet remain difficult to create, share, and use. Stakeholder perspectives are needed to inform usable approaches.

Origin and Geochronology of Chang'anpu Mo-Cu Deposit in Jilin Province: Constraints from Molybdenite Re-Os Isotope Systematics

Yankuang ceshi, 2016
The east-central part of Jilin Province, located on the continental margin of northeast China along the eastern Xing-Meng orogenic belt, hosts more than 10 large-and medium-scale Mo deposits. The major types of mineralization include porphyry, skarn, and

The Implications of HClO₄ for Dissolving Large Masses of Low Level Os in Metal Sulfides and Factors that Influence Re-Os Dating

Applied Sciences, 2020
In general, no more than 1 g of metal sulfide can be completely digested in 20 mL of inverse aqua regia using the Carius tube technique. In this study, the sample weight increased after adding HClO4 to inverse aqua regia while the volume of acid ...

Re‐Os isotope systematics in carbonates from Serpent Mound, Ohio: Implications for Re‐Os dating of crustal rocks and the osmium isotopic composition of Ordovician seawater [PDF]

Geochemistry, Geophysics, Geosystems, 2004
Eleven core samples of Ordovician carbonates and shale from within and nearby the Serpent Mound (Ohio) cryptoexplosion structure were analyzed for Re‐Os isotopes. Whole‐rock samples span a large range in measured 187Os/188Os (0.714 to 6.083), and exhibit a linear correlation of 187Os/188Os with 187Re/188Os.
