Abstract:
Lunar lineaments within 50° north and south latitudes of lunar nearside have been mapped based on the Chang'E-1 CCD image data and other lunar scientific data. Landform features and spatial distribution of mare ridges and lunar grabens have been analyzed. Mare subsidence model was used to analyze the genetic mechanism of mare ridges and lunar grabens, and Digital Elevation Model (DEM) data and gravity data were used to predict the distribution of mare ridges. In mascon basins, the genetic connection between mare ridges and lunar grabens was mainly caused by the local stress of mare subsidence. The geometry of the load and the pre-mare isostatic state of the basin probably influenced the distribution of concentric and radial mare ridges.
