Abstract To better constrain the evolution of Mongol‐Okhotsk suture, we carried out new paleomagnetic studies on Sharilyn Formation (~155 Ma) and Tsagantsav (~130 in southern Mongolia, Amuria Block (AMU), Tuchengzi (~140 Dadianzi/Yixian Yanshan belt, North China (NCB). A total 719 collected samples (from 100 sites) were subjected to stepwise thermal demagnetization. After a low‐temperature component viscous magnetic remanence acquired recent field was removed, stable high‐temperature...
Abstract We have conducted an extensive towed-magnetic-sled survey during the period 2023 June 14–28, over seafloor about 85 km north of Manus Island, Papua New Guinea, centered around calculated path bolide CNEOS 2014 January 8 (IM1). found 850 spherules diameter 0.05–1.3 mm in our samples. They were analyzed by microXRF, Electron Probe Microanalyzer and ICP Mass spectrometry. identified 22% as product planetary igneous differentiation labeled them D-type spherules. A small portion...
Abstract Mass-dependent stable isotopic variations recorded in lunar samples provide novel resolution to the formation and differentiation history of Moon. In this study, we report new high-precision Ca-isotope measurements for rocks minerals. data modeling magma ocean together demonstrate indistinguishable mass-dependent Ca compositions bulk silicate Earth This implied Earth-Moon isotope equilibration is consistent with Moon’s high-energy giant-impact (Synestia) origin not readily...
Abstract The Tonian supercontinent Rodinia is hypothesized to have included almost all Proterozoic continental blocks. Competing models variably place South China at the core or periphery of separated from it entirely. paleogeographic also vary in whether they incorporate large and rapid oscillatory true polar wander associated with ca. 810–795 Ma Bitter Springs Stage. Here, we present paleomagnetic data paired U‐Pb chemical abrasion isotope dilution thermal ionization mass spectrometry...
The rate of movement Earth's solid shell relative to its spin axis, or true polar wander, depends on variations in mantle convection and viscosity. We report paleomagnetic geochronologic data from South China that constrain the rapid wander (>5° per million years) between 832 years 821 ago. Analysis database demonstrates secular change related cooling thermal structure across supercontinent cycles. True rates are relatively muted with a partially insulated during assembly accelerate as...
We have conducted an extensive towed-magnetic-sled survey during the period 14-28 June, 2023, over seafloor centered around calculated path of bolide CNEOS 2014-01-08 (IM1) about 85 km north Manus Island, Papua New Guinea. found 700 spherules diameter 0.05-1.3 millimeters in our samples, which 57 were analyzed so far. The significantly concentrated along expected meteor path. Mass spectrometry 47 near high-yield regions IM1's reveals a distinct extra-solar abundance pattern for 5 them, while...
We have conducted an extensive towed-magnetic-sled survey during the period of June 14-28, 2023, over seafloor about 85 km north Manus Island, Papua New Guinea, centered around calculated path bolide CNEOS 2014-01-08 (IM1). found 850 spherules diameter 0.1-1.3 millimeters in our samples. The samples were analyzed by micro-XRF, Electron Probe Microanalyzer and ICP Mass spectrometry. Here we report major trace element compositions classify based on that analysis. identified 78% as primitive,...
Abstract Stable isotopic variations recorded in lunar samples provide novel and crucial resolution to the differentiation history of Moon. We report new high-precision Ca-isotope measurements for rocks minerals. data modeling magma ocean together demonstrate indistinguishable Ca compositions between bulk silicate Earth Moon, consistent with isotope equilibration Moon preceding differentiation. This is also high-energy giant impact (Synestia) origin Earth-Moon system. Moreover,...
The rate of movement Earth’s solid shell relative to its spin axis, or true polar wander, depends on variations in mantle convection and viscosity. We report paleomagnetic geochronologic data from South China that constrain the rapid wander (>5° Myr-1) 832–821 million years ago. Analysis database demonstrates secular change related cooling thermal structure across supercontinent cycles.
