Understanding the rheology of the Earth's lower mantle is essential for modelling mantle convection and its consequences for the geodynamical, thermal and chemical evolution of the planet. However, the extreme pressure-temperature condition...
Application of microsublimation for sample purification in compound-specific radiocarbon analysis [0.03%]

IDEFIX, the Martian Moons eXploration (MMX) mission Phobos rover, will be the first of its kind to attempt wheeled-locomotion on a low-gravity surface. The IDEFIX WheelCams, two cameras placed on the underside of the rover looking at the ro...
Effect of bridgmanite-ferropericlase grain size evolution on Earth's average mantle viscosity: implications for mantle convection in early and present-day Earth [0.03%]
桥玄岩-铁尖晶石橄榄岩粒度变化对地幔平均黏度的影响：对早期和现今地球地幔对流的启示
Jyotirmoy Paul,Gregor J Golabek,Antoine B Rozel et al.
Jyotirmoy Paul et al.
Recent experimental investigations of grain size evolution in bridgmanite-ferropericlase assemblages have suggested very slow growth for these bimodal phases. Despite numerous speculations on grain size-dependent viscosity, a comprehensive ...
Regionally extensive ejecta layer of the Australasian tektite strewn field: the MIS 20/19 large meteorite impact in mainland South-East Asia [0.03%]
澳大利亚微玻璃层的区域分布：东南亚地区间期20/19特大型撞击事件
Paul A Carling,Toshihiro Tada,Ryuji Tada et al.
Paul A Carling et al.
Aspects of the Quaternary sedimentary geology of South-East Asia have proven problematic in terms of interpretation as to the origins and relationships of the surface sediment layers. The MIS 20 large meteorite impact (c., 788 to 785 ka) oc...
Near-real-time estimation of fossil fuel CO2 emissions from China based on atmospheric observations on Hateruma and Yonaguni Islands, Japan [0.03%]
基于日本种子岛和与那国岛大气观测的中国化石燃料二氧化碳排放通量的高时空分辨率反演估算研究
Yasunori Tohjima,Yosuke Niwa,Prabir K Patra et al.
Yasunori Tohjima et al.
We developed a near-real-time estimation method for temporal changes in fossil fuel CO2 (FFCO2) emissions from China for 3 months [January, February, March (JFM)] based on atmospheric CO2 and CH4 observations on Hateruma Island (HAT, 24.06...
Capability of airline jets as an observation platform for noctilucent clouds at middle latitudes [0.03%]
民航客机作为中纬度夜光云观测平台的能力评估
Hidehiko Suzuki,Ayako Matsumoto,Peter Dalin et al.
Hidehiko Suzuki et al.
The exact occurrence frequency of noctilucent clouds (NLCs) in middle latitudes is significant information because it is thought to be sensitive to long-term atmospheric change. We conducted NLC observation from airline jets in the Northern...
Formation, preservation and extinction of high-pressure minerals in meteorites: temperature effects in shock metamorphism and shock classification [0.03%]
陨石中的高压矿物的形成、保存及消失：冲击变质作用中的温度效应及其在冲击分类学上的应用
Jinping Hu,Thomas G Sharp
Jinping Hu
The goal of classifying shock metamorphic features in meteorites is to estimate the corresponding shock pressure conditions. However, the temperature variability of shock metamorphism is equally important and can result in a diverse and het...
