In this paper, the recent achivements of shock wave physics applied to Earth and Planetary Sciences are reviewed, including the state and composition of Earth interior, the compositional models of major planets, and the processes of impacting, createring and accreting in the solar system. With the development of shock compression methods for obtaining pressure density Hugoniot curve, it become clear that these can be applied to both determining the equation of state and investigating polymorphic phase changes in silicate minerals of planetary mantles and crusts, as well as the iron alloys of the metallic cores of terrestrial planets. These data, when taken with seismological models of the Earth, yield constraints on the composition of the Earth's mantle and core. Whereas, the data above and other similar data for low temperature condensable gases (H 2, He) and ices (H 2O, CH 4, CO 2, NH 3), combined with solar elements abundance and Jeffrey's number data, have been used to construct compositional models of the major planets (e.g., Jupiter and Saturm). Shock temperature measurements of the possible minerals in the Earth interior could be applied to investigate their melting behaviors , with which a phase diagram at high pressures could be constructed , and could provide a constraint to the quasi-static creep rheology of the mantle that controls convection. Shock compression of molten silicates at upper mantle pressures provides a constraint on the depths in the mantle from which molten lava can reach the surface as a result of its buoyancy relative to the surrounding solid. Application of shock wave data is critical to describe the energy partitioning upon hypervelocity impact on planetary surface, and permits caculation of the melt and vapor produced by impactors as a function of impact velocity, as well as provides a quantitative basis for determining the degree of erosion or accretion upon planetary impact as a function of impact and planetary escape velocity. On the other hand, shock induced devolatization during the impact processes is also addressable using shock wave and other thermodynamic data, and can be used to depict the formation of Earth's primitive atomsphere. Furthermore, giant impacts upon the Earth surface could release plenty of gases, such as CO 2 and SO 2 into the atmosphere that strongly affect the global climate, which appears to have played a major role in the evolution and extinction of species during the Earth's history.

In this paper, the recent achievements of dynamic high-pressure physics applied to Earth and Planetary Sciences are reviewed. This includes the state and composition of Earth's interior, the compositional models of major planets, and processes of impacting, cratering and accreting in the solar system. Shock wave data for iron, combined with other thermodynamic data, yield a uniform melting curve of iron for both dynamic and static high pressure data. The data also indicate that the melting temperature of iron at the inner core boundary (ICB),or the anchor temperature, is about (5 950±100) K. Shock Hugoniot data, in conjuction with seismological models of the Earth, yield constraints on the composition of the Earth’s mantle and core. The sound velocity measurements for silicate such as (Mg_(0.9),Fe_(0.1))SiO_(3 )(perovskite) under shock compression imply that the discontinuity at the depth of 1 770 km is not only a phase transition boundary but also a compositional boundary. Whereas, the shock data and other similar data for low temperature condensable gases (H_2,He) and ices (H_2O, CH_(4), CO_2, NH_3, and N_2), combined with solar elements abundance and Jeffrey's number data, have been used to construct compositional models of the major planets (e. g., Jupiter and Saturn). Shock temperature measurements of the possible minerals in the Earth's interior could be applied to investigate their melting behaviors, with which high pressures phase diagrams could be constructed. This would provide constraints to the quasi-static creep rheology of the mantle that controls convection. Shock compression of molten silicates at upper mantle pressures provides constraints on the depths in the mantle from which melts can reach the surface. Application of shock wave data is critical to describe the energy partitioning upon hypervelocity impacts on planetary surfaces. These data permit calculation of the melt and vapor produced by impactors as a function of impact velocity, and provide a quantitative basis for determining the impact-induced melting of near-surface water ice on Mars. Shock induced devolatilization during the impact processes can also be described using shock wave and other thermodynamic data, and can be used to model the formation of Earth's primitive atmosphere. Furthermore, giant impacts upon the Earth's surface could release abundant gases, such as CO_(2 )and SO_(2 )into the atmosphere that strongly affect the global climate, which appears to have played a major role in the evolution and extinction of species during the Earth's history.

综述了动高压物理应用于地球和行星科学研究中的一些最新进展,包括地球内部的物质组成与热力学状态,巨行星的物质组成模型,太阳系中的碰撞成坑与吸积相互作用等。依据铁的冲击波数据,结合其他热力学数据,可以得到一条统一的铁的熔化曲线,将动高压与静高压数据完全统一,初步解决了长期困扰高压界的动、静压关于铁的熔化温度存在系统偏差的诘难。外推到ICB处(330 GPa),铁的熔化温度(亦称锚定温度)约为(5 950±100) K。冲击Hugoniot 数据,结合地震学模型可以约束地幔与地核的物质组成。冲击压缩下钙钛矿型(Mg0 9,Fe0 1)SiO3的高压声速测量结果表明,1 770 km深度的不连续面不仅是一个相变界面而且是一个化学成分或矿物学分界面。低温可凝聚气体(H2、He)或冰(H2 O, CH4, CO2, NH3 和N2 )的冲击波数据,及Jeffrey 数等其他数据可以用来构建巨行星(如木星和土星)的物质组成模型。地球深部矿物的冲击温度测量可以用来研究它们的高压熔化行为,据此建立的高压相图可以为控制地幔对流的地幔物质的准静态蠕变提供约束条件。熔融硅酸盐在上地幔压力条件下的冲击压缩数据,可以约束地幔熔岩稳定存在...
