对木卫三和木卫四上的环形山和逆冲断层的形态特征进行了观测，并对这两颗卫星的地壳性质及其演化进行了研究。分别描述了木卫四上的碗状陨石坑、光滑的红色陨石坑、无中心峰的陨石坑、有中心坑的陨石坑、链式陨石坑、木卫三上的吉尔伽美什盆地和西赤道盆地、陨石坑的palimpsests和penepalimpsests、木卫四上的多环结构以及木卫三上的Galileo Regio边缘沟系统。地壳演化是通过研究伽利略地区系统的发展，陨石坑保留年龄的分布，射线团的记录，木卫三岩石圈的热历史，和中央坑的起源。有人建议，作为岩石圈的每个卫星冷却和增厚，陨石坑的滞留传播作为一个波从极地地区和antapex向顶点，在任何给定的位置，随着时间的推移，逐渐较大的陨石坑被保留。
The morphologic characteristics of craters and palimpsests on Ganymede and Callisto are surveyed, and the crustal properties of these satellites and the evolution of the properties are studied. The morphology of bowl-shaped craters, smooth-floored craters, craters without central peaks, craters with central pits, chain craters on Callisto, the Gilgamesh and Western Equatorial Basins on Ganymede, crater palimpsests and penepalimpsests, multiring structures on Callisto, and the Galileo Regio rimmed furrow system on Ganymede are described individually. The crustal evolution is addressed by examining the development of the Galileo Regio system, the distribution of crater retention ages, the record of ray clusters, the thermal history of the lithosphere of Ganymede, and the origin of the central pits. It is suggested that as the lithosphere of each satellite cooled and thickened, crater retentivity spread as a wave from the polar regions and the antapex toward the apex; at any given location, progressively larger craters were retained with the passage of time.
