嫦娥六号月球样品研究新进展发布 中国科学家研究发现月球背面月幔有点“冷”

Core Findings - The research reveals that the lunar mantle on the far side of the Moon is cooler compared to the near side, enhancing the understanding of the Moon's "bipolarity" phenomenon [1][9] - This study provides critical scientific data for understanding the evolution of the Moon and its distinct characteristics [1] Research Methodology - Scientists conducted a detailed analysis of basalt samples brought back by the Chang'e 6 mission, utilizing various methods to determine the crystallization temperature and pressure of minerals such as clinopyroxene and plagioclase [4] - The crystallization temperature of the Chang'e 6 basalt samples was found to be approximately 1100°C, which is about 100°C lower than samples from the Chang'e 5 mission on the near side [4][6] Temperature Findings - The potential temperature of the lunar mantle on the far side is estimated to be around 1400°C, which is lower than the near side's estimated 1500°C [6] - Remote sensing data corroborated these findings, indicating that the potential temperature of the lunar mantle on the far side is approximately 70°C lower than that of the near side [6] Lunar Characteristics - The study highlights significant differences between the near and far sides of the Moon in terms of topography, elemental distribution, and geological features, which are collectively referred to as the "bipolarity" phenomenon [9] - The near side is characterized by a relatively flat terrain with extensive basaltic plains, while the far side features a more rugged landscape with fewer basaltic areas [9]
