| Research Abstract |
Based on geological survey of Lonar crater, India, we revealed hydrological cycles surrounding the crater, especially responses to Asian monsonn. We also discussed formation processes of lake sediments on ancient Mars, based on the knowledge of formation and modification processes occurring on the Lonar crater. In addition, we investigated the surface ages from the cosmogenic species contained in the rocks surrounding the crater. We discussed the erosion rate and its timescales on the Earth and ancient Mars.
