Interactions between magma oceans and overlying atmospheres on young rocky planets leads to an evolving feedback of outgassing, greenhouse forcing, and mantle melt fraction. Previous studies have predominantly focused on the solidification ...
Mapping of Western Valles Marineris Light-Toned Layered Deposits and Newly Classified Rim Deposits [0.03%]
西方水手号谷浅色层状沉积物及新归类的边缘沉积物分布图测绘
Ivan G Mishev,Isaac B Smith,Cathy Quantin et al.
Ivan G Mishev et al.
Layered deposits are found on the plateaus surrounding the western portion of Valles Marineris, mantling the chasmata rims. These rim deposits exhibit intricate layering and are described as light-toned layered deposits (LLDs) in previous s...
Extensive Secondary Cratering From the InSight Sol 1034a Impact Event [0.03%]
洞察号探测器Sol 1034a火星表面撞击事件诱发的次级坑系

P M Grindrod et al.
Impact cratering is one of the fundamental processes throughout the history of the Solar System. The formation of new impact craters on planetary bodies has been observed with repeat images from orbiting satellites. However, the time gap be...
Using the Melosh Model of Acoustic Fluidization to Simulate Impact Crater Collapse on the Earth and Moon [0.03%]
利用Melosh声学流化模型模拟地球和月球撞击坑的崩塌现象
A Rajšić,B C Johnson,G S Collins et al.
A Rajšić et al.
The formation of complex craters requires some form of transient weakening of target rocks. Acoustic fluidization is one proposed mechanism applied in many numerical simulations of large crater formation. In a companion paper, we describe i...
Complex Crater Collapse: A Comparison of the Block and Melosh Acoustic Fluidization Models of Transient Target Weakening [0.03%]
复杂撞击坑退化的研究：块体模型与梅洛声致流化模型的对比分析

Hamish C F C Hay et al.
The collapse of large impact craters requires a temporary reduction in the resistance to shear deformation of the target rocks. One explanation for such weakening is acoustic fluidization, where impact-generated pressure fluctuations tempor...
Characterizing the Modulation and Activation-Triggering Mechanisms of Main-Belt Comets via 3D Thermophysical Modeling of an Ellipsoidal Body [0.03%]

The diversity and abundance of diagenetic textures observed in sedimentary rocks of the clay-sulfate transition recorded in the stratigraphic record of Gale crater are distinctive within the rover's traverse. This study catalogs all texture...
Environmental Changes Recorded in Sedimentary Rocks in the Clay-Sulfate Transition Region in Gale Crater, Mars: Results From the Sample Analysis at Mars-Evolved Gas Analysis Instrument Onboard the Mars Science Laboratory Curiosity Rover [0.03%]
火星盖尔陨石坑粘土-硫酸盐过渡区记录的环境变化：来自好奇号上的样本分析在火星- evolved gas analysis仪器的结果

J V Clark et al.
The Curiosity rover explored the region between the orbitally defined phyllosilicate-bearing Glen Torridon trough and the overlying layered sulfate-bearing unit, called the "clay-sulfate transition region." Samples were drilled from the top...
High Pressure Melting Curve of Fe-Si: Implication for the Thermal Properties in Mercury's Core [0.03%]
高压下Fe-Si熔点曲线：对水星核心热性质的启示

Innocent C Ezenwa et al.
The motion of liquid iron (Fe) alloy materials in the outer core drives the dynamo, which generates Mercury's magnetic field. The assessment of core models requires laboratory measurements of the melting temperature of Fe alloys at high pre...
