Gravity aspects from recent gravity field model GRGM1200A of the Moon and analysis of magnetic data

Study of the Buried Basin C-H, Based on the Multi-Source Remote Sensing Data

“…In addition to the intrusive basalts, the ejecta from the Copernicus impact event in about 800 Ma and the weathering processes also cause the disappearance of the C-H basin's rim from the lunar surface. The Bouguer gravity anomaly was formed by the mantle upwelling [20]. However, the lunar dynamo likely ceased sometime between 1.92 Ga-0.80 Ga [52], earlier than the formation of Copernicus.…”

“…The study of Klokočník et al did not focus on the features except the gravity and magnetism. They only pointed out that the diameter of the C-H basin had ahigh gravity anomaly that is about 150-160 km and they did not indicate the center position of the C-H basin [20].…”

Solomon and Head [41] discovered that all of the mascon basins display an associated tectonic feature: the linear rilles or mare ridges tend to be concentric to the mascon.…”

“…The Moon LRO LROC WAC Global Morphology Mosaic (100 m/pixel) and Moon LROC WAC DTM GLD100 In the south-eastern area of the Copernicus crater, a buried basin is present, called C-H [16]. The classification of the basin's type and the diameter is uncertain [13,16,20,24]. Such cases suggest that the current basin catalogs need further correction.…”

“…The GRAIL data also played an important role in clarifying the theory that mascons are caused by an isostatic adjustment, cooling and contraction of a voluminous melt pool [11,[17][18][19]. Klokočník et al used gravity aspects (the gravity disturbance, the Marussi tensor, two gravity invariants, dimensionality ratio, the strike angles, and the virtual deformations) to study the Copernicus area and amended the definition of 'mascon' into: "An object that has dilatation regime of the virtual deformations in the crater center while the rims are in compressional regime [20]". However, most of the above studies were based on the gravitational and topographical data and hardly brought in remote sensing images to try to prove their inference.…”
