Lunar detecting data,such as topography and gravity,have made it possible to interpret this hemisphere dichotomy. The high-resolution lunar topographic model CLTM-s01 has revealed that there still exist four unknown features,namely,quasi-impact basin Sternfeld-Lewis (20°S,232°E),confirmed impact basin Fitzgerald-Jackson (25°N,191°E),crater Wugang (13°N,189°E) and volcanic deposited highland Yutu (14°N,308°E). Furthermore,we analyzed and identified about eleven large-scale impact basins that have been proposed since 1994,and classified them according to their circular characteristics.展开更多
