| Outline of Final Research Achievements |
The current lunar global geological map was generated in 1980’s. It has been used widely and contributed greatly to the lunar science. The goal of this study is to generate new global lunar geological map, which includes new rock types we found from recent lunar exploration data, and to understand the lunar evolution history based on that.
Firstly, we generated a geological unit map based on the SELENE (Kaguya) Spectral Profiler data by applying mathematical analyses method. Then, we evaluated and gave geologic interpretations to the units and generated the global lunar geologic map. And from the map, we found that total surface area of the old mare hidden under the surface layer (or crustal intrusion of basaltic composition) is significantly (max. 2 times) higher than the previous estimation. This finding is very important to understand volcanic history of the Moon. We submitted a paper discussing our results and it is currently under the revision.
