Abstract:

The Petavius quadrangle (LQ-21) is located at the junction of the near and far sides of the Moon in the transition zone between the mare and highland terrain. Large impact basins such as Nectaris, Foecunditatis, and Smythii basins are developed around this region. Understanding the geological development of this area is helpful for understanding the development and evolutionary history of the Moon. Accordingly, this area is a key area in the digital geological mapping of the Moon. This work combines the Chang’E-1(CE-1) CCD image data, interference imaging spectrometer(IIM) data, laser altimeter (LAM) data, Chang’E-2(CE-2) CCD image data, as well as other lunar geological data, to study the material composition, structural elements, and geochronology of the lunar surface, and to compile the lunar geological map using the ArcGIS platform. So far, we have completed the geological map of the Petavius quadrangle at 1: 2.5 million scale, summarized the regional geological evolutionary history, and established a spatial database for the geological map of this region.

Key words: Moon, Petavius, Langrenus, geological evolution, digital geological mapping
