Science：龙宫小行星为CI型碳质球粒陨石（图）
龙宫小行星 CI型 碳质球粒陨石
2023/1/14
在宏观研究前沿，我们所有的终极问题，可以总结为“一黑两暗三起源”。 “一黑”就是黑洞；“两暗”就是暗物质和暗能量；“三起源”就是指宇宙的起源、生命的起源和意识的起源。小行星作为太阳系形成和演化的“化石”，是揭示太阳系起源的重要窗口。在百万计的小行星中，有一类C型小行星（parent bodies of carbonaceous chondrites），它们富含碳、水等挥发分，以及丰富的氨基酸等有机...
Science：卤水破坏了火星盖尔陨石坑沉积岩中的粘土矿物（图）
卤水 火星盖尔陨石坑 沉积岩 粘土矿物
2023/1/14
火星的沉积岩记录保存了数十亿年前发生在这个星球上的地质学和潜在的天体生物学过程的信息。盖尔陨石坑形成于36亿年前，曾经是一个湖泊。轨道和好奇号探测显示，盖尔陨石坑的沉积岩垂直厚度可达几百米，这些沉积岩中含有大量粘土矿物——蒙脱石。蒙脱石族矿物是一类表面积大、负静电电荷高的粘土矿物，可吸附有机质，因此蒙脱石的存在有利于有机质在地质记录中保存。以前人们一般倾向于认为，陨石坑底部的蒙脱石形成后基本上没有...
