The crystallization age of an Apollo 15 anorthosite rock, 15415,9, returned from the lunar highlands has been measured to be (4.09 +/- 0.19) x 10(9) years. The primitive lunar crust must have been formed in the first 300 to 400 x 10(6) years. The results give some credence to the hypothesis that the primitive lunar surface was molten and large-scale fractional crystallization occurred in the early history of the moon.
从月球高地返回的一块编号为15415,9的阿波罗15号斜长岩的结晶年龄经测定为(4.09±0.19)×10⁹年。原始月壳必定是在最初的30亿至40亿年中形成的。这些结果为原始月球表面处于熔融状态且在月球早期历史中发生了大规模分离结晶这一假说提供了一定可信度。
