摘要:
根据以GRAIL重力场数据和LOLA地形数据计算的月壳厚度,将月球构造格架初步划分为三个构造单元:主要覆盖月球正面风暴洋区域的月海构造单元、主要覆盖月球背面高地的月陆构造单元以及主要位于南半球背面的南极艾肯盆地构造单元。结合最新的研究成果,对各构造单元上的重大地质事件包括岩浆事件、火山事件和撞击事件分别进行了简单的梳理,结果表明月球不同构造单元的演化事件具有明显的差异。

Abstract:
Based on the lunar crust thickness which is inversed from the GRAIL gravity data and LOLA topography data, the lunar tectonic framework can be preliminarily divided into three units: the mare tectonics locates in the region which mainly covers the nearside procellarum, the land tectonics dominately covering the highland in the farside and the south pole aitken basin tectonics. The major geological events including magma processing, volcanism and meteorite impacting have been studied simply, implying that the three kinds of evolution events vary clearly in different tectonic units.
