国际空间站第75远征队的宇航员于2026年8月28日拍摄到马达加斯加南部的一处特殊地质构造——萨里里亚基斜长岩地体1。这一岩石区域面积约100平方公里，其矿物组成与月球表面明亮高地的主要成分相同1。
该斜长岩构造距今至少6亿年，其周围岩石保存了冈瓦纳超大陆形成期间古陆块碰撞的证据1。相比之下，月球的亮色高地主要由年代超过40亿年的斜长岩组成1。这一发现对研究月球早期形成和演化具有重要科学价值1。地球上其他地区如蒙大拿州比尔托斯山脉也存在成分与月球斜长岩相近的地质构造1。
Astronauts aboard the International Space Station photographed a vast anorthosite formation in southern Madagascar on August 28, 2026, revealing a geological structure strikingly similar to the Moon's bright highlands.1 The Saririakie anorthosite body spans approximately 100 square kilometers and consists of rock material composed of the same mineral as the Moon's luminous highland regions.1
The formation dates back at least 600 million years and preserves evidence of ancient continental collisions that occurred during the assembly of the supercontinent Gondwana.1 Scientists regard this discovery as particularly valuable for understanding the Moon's early formation and evolution, as the bright highlands covering much of the lunar surface are primarily composed of anorthosite and are over 4 billion years old.1 Similar anorthosite deposits have been identified in Montana's Beartooth Mountains, with anorthosite compositions comparable to lunar anorthosite.1
