摘要
月球的起源与演化以及月球正面与背面的差异性一直是科学研究的热点问题,月球正面和背面的差异性说明两个半球的演化过程存在不对称性。通过分析月球正面与背面的物理特征、岩石矿物特征和构造特征分布差异,研究形成月球正面和背面差异性的动力过程,进而解释月球正面与背面地质演化差异。结果表明:月球正面和背面的物理特征、岩石矿物特征和构造特征都存在很大的不同;月球正面和背面的地质演化可以划分为以内动力地质作用为主的阶段,内、外动力地质作用并存阶段和以外动力地质作用为主的阶段;以内动力地质作用为主的阶段和内、外动力地质作用并存阶段是造成月球正面和背面地质演化差异的两个主要阶段,而以外动力地质作用为主的阶段对月球正面和背面地质演化差异的形成影响较小。
The origin and evolution of Moon and the difference between lunar nearside and farside are hot topics.The difference between lunar nearside and farside shows the asymmetry evolution of the two hemispheres.Based on the analysis of the physical properties,rock mineral properties and structural characteristics of lunar nearside and farside,the difference of their geological evolution and the dynamic process of their formations were discussed.The results show that the physical properties,rock mineral properties and structural characteristics of lunar nearside and farside are different;the geological evolution history of Moon can be divided into three stages,including the stage of endogenic geological process,the stage of both endogenic and exogenicgeological processes and the stage of exogenic geological process;the differences between lunar nearside and farside are mainly affected by the stage of endogenic geological process and the stage of both endogenic and exogenic geological processes,while the stage of exogenic geological process only takes little effect on lunar nearside and farside.
