📌 概要

研究人员借助月球样本方法，通过二氧化硅（SiO2）丰度分析水星地壳成因，发现远古水星地壳由极端火山活动形成。基于NASA信使号数据的假彩色图像显示，水星表面存在大面积熔岩平原与富暗色矿物区域，揭示了其岩浆演化与火山喷发历史。

⚡ 关键要点

▸新研究利用月球样本类比方法解析水星火山活动
▸二氧化硅丰度是判断岩浆性质与火山活动的关键指标
▸MESSENGER假彩色图像显示水星存在熔岩平原和富暗色矿物区

This false-color image of Mercury was created with images from NASA's MESSENGER spacecraft. The colors enhance different features on Mercury, including its chemical and mineralogical composition. The tan areas are lava plains and the blue areas are rich in darker minerals. Image Credit: NASA/(NASA PIA16853).

Researchers have figured out how to use lunar samples to determine the nature of volcanic activity on ancient Mercury. It's all based on SiO2, or silicon dioxide. Its abundance in a planet's crust reveals a lot about magma and volcanic activity.
