Dating of the lunar surface plays a key role in understanding and reconstruction of lunar geological evolution, and crater sizefrequency distribution method (CSFD) could get the absolute geological age of a specific geological unit according to crater density of different sizes in the region. This paper extracted the impact craters automatically from the images and terrain data in the area of impact craters with three methods. Basalt of the northern part of Mare Imbrium and in the northeastern Oceanus Procellarum was partitioned by Clementine spectral data, and dating results of each basalt region were obtained by using CSFD. The authors found that there is a certain deviation in the dating results obtained by means of automatic identification comparing with previous dating data in the region, but for each partition the new and old overall trend is basically consistent with the previous research results. The automatic identification dating results show that for the basalt areas, the geochronolgy roughly is as follows: eastern Mare Imbrium (3.56 Ga)Sinus Iridium (3.38 Ga) northeastern Oceanus Procellarum (2.74 Ga)western Mare Imbrium (2.63 Ga) Crater Plato (2.37 Ga).
