通过马里纳10号经度0~188半球航空摄影发现,水星表面也象月球表面那样覆盖着无数陨石坑。水星上最大构造为卡罗里斯盆地,呈近圆形,直径1,300km,盆地边缘高出约2km,在这里排列着中央有圆丘状突起的陨石坑(Cfater),并出外伸展着一些山岭和谷地。这些与月球上的雨海极为相似。盆地的底面山条带状的山脊和裂隙形成。盆地的原始形状据 Through aerial photography of the longitude 0 to 188 hemispheres of Marina 11, it was found that the surface of Mercury is also covered with numerous craters like the moon’s surface. Mercury is the largest structure of the Carollis basin, was nearly circular, diameter of 1,300 km, about 2 km above the edge of the basin, where there are arranged in the central dome of craters (Cfater), and out of some stretches of mountains and Valley. These are very similar to the rainy sea on the moon. Ridges and crevasses formed at the base of mountain basins. According to the original shape of the basin
