The exploration of the surface geology of Venus has been hampered by its inhospitable conditions and thick and opaque atmosphere. Fundamental properties, such as crustal composition and heterogeneity remain poorly constrained. Multiple analytical techniques are required to better understand its geology. A spectroscopy‐based study laboratory study of the emissivity properties of Venus‐relevant igneous rocks, measured at 440 °C by Dyar et al. (2020b; https://doi.org/10.1029/2020GL090497) shows that the use of multiple atmospheric windows in the 1‐µm region can provide strong constraints on the FeO content of Venus‐relevant igneous rocks, and by extension, the type of igneous rock. These results will improve our ability to map the surface geology of Venus remotely.

透过金星的气氛看：表面上有什么？

金星的地表地质条件受其恶劣的条件以及浓密而不透明的大气所阻碍。诸如地壳组成和非均质性之类的基本属性仍然受到严格限制。需要多种分析技术来更好地了解其地质状况。Dyar等人在440°C下对金星相关火成岩的发射率特性进行了基于光谱的研究实验室研究。（2020b; https://doi.org/10.1029/2020GL090497）显示，在1 µm区域中使用多个大气窗口可以对金星相关火成岩的FeO含量提供严格的限制，并由此扩展其类型。火成岩。这些结果将提高我们远程绘制金星表面地质图的能力。
